Custodianship
Hi Mike. Thanks for mentoring. My probationary period is over and there's a vote on me for full custodianship. --AFriedman (talk) 18:39, 5 February 2010 (UTC)

Thanks man
Hi, well im pretty much a newbie here, not to mention that Im from Costa Rica so my english is not the best, but I'll try. Im a software engineer so maybe I try contributing in that topic. --Keylor 14:08, 20 February 2010 (UTC)

Wikiversity Nomic - Call for judgement
Hi! I entered as a player in the Nomic, and then when I saw the possibility there did a rather boring bid for winning. I won't say I won't be happiest if it is judged as valid, and I actually think it looks legit (if perhaps, a bit boring), but I'm also interested to see how it will be handled - and however it goes, perhaps it turns out it was what was needed to get the game going? So, will you take a look and comment at Talk:Nomic? I'll also post on User:Kennercat's talk page. Anyone else who should be contacted? Ever wonder 11:50, 9 April 2010 (UTC)

Tools
Hi Mike. There are some interesting things going on here lately, some of them not so good. If you don't mind, please restore my tools, which I had relinquished a while ago thinking that I would not want to use them again. Things are a bit out of balance, and I'd like to perform a few actions in the interests of restoring that balance. I'll probably not keep them for more than a month or so, but we'll see. --SB_Johnny talk 23:39, 11 August 2010 (UTC)

 * I've undone your voluntary relinquishment of the tools. Good luck with the mop!  --mikeu talk 23:49, 11 August 2010 (UTC)

 * This is not good Mikeu. We have a procedure. Do you know why? Why you should be that only one who say, this user I like so he/she can take back his rights, while this user I dont like... It is up to community if they want such a custodian or not--Juan de Vojníkov 06:00, 12 August 2010 (UTC)

 * Thanks! I'll figure out what to do with them tomorrow... farm chores to do! --SB_Johnny talk 23:57, 11 August 2010 (UTC)

 * It wasn't a voluntary relinquishment. He was regranted it by whim of Jimbo after SB Johnny promised to stop the drama. Instead, SB Johnny redid the drama. We do not have a policy stating that those who give it up for any reason can be granted the tools upon request regardless. Mike, it is also troubling that you would do this without discussion especially without having any active role in this community for a while. Ottava Rima (talk) 00:46, 12 August 2010 (UTC)
 * Did SB Johnny retire amidst a drama? If not, he can request the tools back whenever he want(ed). Diego Grez 00:54, 12 August 2010 (UTC)
 * No. He cannot. That is Wikipedia. We are not Wikipedia. But he did retire amongst drama, drama he created when he decided to wheel war and openly attack the Foundation through his use of ops that made it necessary to remove his ops. Ottava Rima (talk) 00:55, 12 August 2010 (UTC)

 * This argument has been made by Ottava and answered by me elsewhere. He didn't listen. The history is clear. SB_Johhny did "wheel-war" (by a special definition, perhaps not realizing that it wasn't really proper under the circumstances) with Jimbo. Jimbo did remove the tools. But Jimbo then restored them. There was no further hazard to the tools, no process filed here or on meta, no complaint here or on meta that was likely to result in process, therefore no "cloud." Basically, the cloud had passed and the sun had come out. Therefore no reason not to restore the tools. The request and restoration was proper. It is not true that he "attack[ed] the Foundation." But even if he did, that would be completely irrelevant. The Foundation representative, Jimbo, was content to leave the tools in place, appears to have no beef with SBJ. SBJ apparently felt that, at that time, he could not continue, so he went to meta and resigned the tools. It is traditional under those circumstances, volutary resignation, to restore them on request, I have never seen an exception, even with some pretty shaky cases. The restoration of tools leaves the case as it would have been if the sysop simply went away for a while. No drama. No debate.
 * Ottava, as you know, Mike cannot remove the tools. If you believe there has been some violation here, you are free to go to meta and request removal. I do not recommend it at all, you are already in quite enough hot water. --Abd 01:11, 12 August 2010 (UTC)
 * Jimbo restored based on a promise to end the drama. SB Johnny gave them up in order to make the ultimate point, thus breaking his promise to Jimbo. There was a strong cloud. Regardless, we are not Wikipedia and we do not have the "not under cloud" allowance to give custodianship back. Crats here can only act under clear consensus. P.S., if you paid attention I already went to those who can remove the status and requested it. Ottava Rima (talk) 01:13, 12 August 2010 (UTC)

 * Abd - why can't Mike remove tools from other accounts here? Is there no process for requesting such action?
 * Ottava - I hope you don't mean your comment on my talk page. Even if it were appropriate for a steward to get involved, it would not be appropriate for me as I edit here and participate in the community.  But this discussion is the sort of matter that can and should be resolved here.
 * SBJ - re: "a few actions in the interests of restoring that balance." -- hopefully only actions supported by community consensus. :-)  –SJ + > 02:18, 12 August 2010 (UTC)
 * Within policy, and with prior consensus, of course :-). I think the most important and meaningful "action" was just taking up the tools again, tbh... there's been a bit too much of the "custodians are in charge" mentality lately, so having an old-school "no big deal" guy returning to the flock (tools and all) seems to have already shifted the dynamic a bit.
 * I think it's also just a very awkward position for Jtniell to be the only "active" 'crat. Jtniell took a huge leap of faith a couple years ago and invited his students and assistants to come here and share in the creation of and participation in a true OER effort. As the "man in power", he's also been the focus of what must be some rather uncomfortable attention finding himself in the middle of a drama he did not create or contribute to. He's starting a new semester, with new students and new assistants, and if I were him I'd be rather uncomfortable. Wouldn't you?
 * Good to see you here, of course. Could you maybe pop in once a day or so for a while? Wikiversity needs at least one reality check per day, and you seem like you have the skills to provide that :-). --SB_Johnny talk 03:19, 12 August 2010 (UTC)
 * Bureaucrats here cannot lift a bit, they can only promote, not demote, if I understand the restrictions correctly. To remove a custodian bit or a bureaucrat bit takes a steward. It's looking like Ottava is trying to get stewards to act (I haven't looked) without an attempt to find local consensus, which I understand would only happen in some kind of emergency situation, and there is no emergency. Yeah, I'm a little concerned about that comment from SBJ, but I'd suggest taking it straight. I see that SBJ is seeking community consensus on the one issue that's come up, explicitly. Thanks for your concern, Sj. --Abd 02:58, 12 August 2010 (UTC)
 * I was told by two Stewards to mention it to other Stewards. You were easier to contact over talk page than over IRC. More of a "heads up". Ottava Rima (talk) 02:48, 12 August 2010 (UTC)

The process for removing a bit is that a custodian can voluntarily resign or the community can demonstrate consensus and make a request at meta. In either case it is only a steward who has the technical means to flip the bit off, but they will only do it in one of the two cases listed above or due to an extreme emergency. When I go to the Special:UserRights page the check boxes for custodian or crat are grayed out under a column heading titled "Groups you cannot change."

This is not the first time that this has come up. See and. At no point did anyone say "Whoah, mike, what are you doing?" If someone gains the trust of the community and then chooses to resign or take a break I don't see any reason to not reinstate at their request. It would be very different if someone had the tools removed through a community decision. But there never was any community discussion on removing the bits from SBJ. The removal and reinstatement were done unilaterally by Jimbo Wales and his actions did not reflect the wishes of the community. --mikeu talk 14:41, 12 August 2010 (UTC)
 * Mike, I wish you were on IRC at the time because then you would have seen that SB Johnny's actions did not have the support of the community and that Jimbo's actions did have quite a bit of support. SB Johnny's approach caused a lot of headaches and unnecessary drama that took weeks to clean up. Ottava Rima (talk) 18:11, 12 August 2010 (UTC)
 * We can see some of the problem revealed here. Ottava and a few friends had a problem with SBJ's action, others not, but perhaps the latter were not on IRC. (However, I've written a policy proposal that would prohibit what SBJ did, as to the future.)
 * I commented in a few places during that time, here and on meta, and I've never used the WV IRC, and many of us don't use it. ::SB_Johnny and some users had a problem with Jimbo's action, and others did not. From what I can see, the majority of users who commented felt it was inappropriate. Ironically, I don't necessarily agree.
 * Ottava argues that SB_Johnny "caused" a lot of problems. That's irrelevant, not to mention not true. The basic problem was that Jimbo intervened rather clumsily, and not just with SBJ, and these interventions, it must be remembered, were part of what led to his resignation of some of his Founder tools. That was under a cloud, by the way, because at that point the !vote was about 4:1, with roughly 500 comments, as I recall, to remove the founder bit. And I didn't and don't necessarily agree with that removal, I'm just pointing out that there was a whole lot going on besides SBJ. What Mu301 has written is simply correct. And we can see it in the current consensus. What happened on IRC is irrelevant, and for good reason. Thanks, Mike.
 * "Resignation under a cloud" has never been taken to mean "Some users didn't like what the sysop or 'crat did." It means actual process under way, or removal by complaint. I.e., someone complains to a steward, and, before the steward responds, the user resigns the tools. Indeed, Ottava, with no evidence, has elsewhere described this situation that way, "You can't fire me, I quit!" Under those conditions, a steward might consider the situation much more carefully, as would a 'crat. That is not at all what happened. --Abd 19:17, 12 August 2010 (UTC)
 * We aren't Wikipedia. There is no "under a cloud" distinction here. Ottava Rima (talk) 12:18, 13 August 2010 (UTC)
 * We are not Wikipedia. We are not Wikipedia. We are not Wikipedia. Now. There is an "under a cloud" distinction here because it is common sense and 'crats will follow it unless they have a damn good reason not to. And if you don't like that, Ottava, propose policy to the contrary, or propose policy that provides that custodians and 'crats cannot do anything that they are not specifically allowed to do by policy. I don't recommend that. At all. Do you? --Abd 13:48, 13 August 2010 (UTC)
 * Crats can only act through community consensus. Ottava Rima (talk) 17:17, 13 August 2010 (UTC)
 * Bureaucratship is a proposed policy. Claiming that a Bureaucrat may only use tools after a community consensus is established is denying common practice. The exception, promotion discussions, is being mistaken for the general rule. In fact, in almost all actions, the 'crat is exercising discretion, and some actions are done with no discussion at all, beyond, typically, a request and a response. Beware of attachment to outcome, beware of claiming that reality is this or that because it suits what you want at the moment. Absolutely, a 'crat is obligated to respect consensus, and to avoid acting against consensus, that's true. But a 'crat may act in expectation of consensus, in advance of an explicit formation, and the rules are really the same for custodians. As the proposed policy states. --Abd 00:17, 15 August 2010 (UTC)

Hi, I used to be AFriedman and have submitted a username change request. May I please have my custodian privileges moved to my new primary account, User:La comadreja? Thanks, La comadreja formerly AFriedman RESEARCH (talk) 03:15, 23 August 2010 (UTC)

Done Sample Edit
Hi there! As requested, I have completed a sample edit with my bot. See Bots/Status. Sorry for the delay, I could swear I had the page watchlisted, but apparently I did not. - EdoDodo talk 19:28, 12 September 2010 (UTC)

Violation of community trust
Mikeu, you closed the CR section when this motion was passing. That motion shuts down all previous votes and declares them as void. The CR procedures also do not allow voting to happen, especially when voting preceded discussion and was done through canvassing people who were not part of the community.

The review was also closed in four days, which directly defies all norms.

This is an egregious violation, and compounded by your readding SB Johnny's sysops and Crat status without community consensus. Ottava Rima (talk) 01:37, 27 November 2010 (UTC)

Wikiversity:Community Review/Mikeu
Community Review/Mikeu. There will be more added, but I will be consulting with JWS and Moulton about abuses relating to your use of ops regarding them and lacking consensus to do so. Ottava Rima (talk) 01:59, 27 November 2010 (UTC)

 * Mike, the CR filed, cited above, was filed prematurely and, in my view, abusively. I do not believe that there are any issues raised by Ottava there that require a response from you in the CR, but, of course any other user might think differently and request that you respond. I was a bit concerned, and I expressed it there, about the following:
 * The close with less than the seven days provided in custodian policy for desysopping. I do believe that in an emergency, where there is present and ongoing damage, a 'crat may request desysopping at any time, even without discussion, so this might be moot, but you did not declare such an emergency, i.e., a need to act more quickly than the 7 day period, so you might possibly comment on this.
 * You may also have felt that the conclusion was obvious, and that some damage would result from the discussion staying open. Again, if this were explicitly stated, then it might help.
 * Or, you forgot about the 7-day period, in which case an "oops!" might be in order. However, I don't believe that harm is done by the error, the conclusion was forgone, and an "oops!" would simply avoid establishing a precedent. Much of the "support" discussion may have shut down when Ottava appeared to "resign," but then oppose !votes started appearing from "new users," so it's a bit of a mess, complicated with possible canvassing -- which does not need to be decided -- and the misdirection, intended or not, of a false resignation. Nobody wanted to kick a man while he was down.
 * Reviewing your closing statement, just now, I do feel that it was adequate, focusing on the basic issue, the widespread loss of confidence by long-term users, which sidesteps so many of the issues raised in objection. However, if you do wish to comment more thoroughly on your close, either here or in the CR, it might possibly help.
 * Your review and close with this unfortunate incident is appreciated. Thanks. --Abd 21:22, 27 November 2010 (UTC)

Thanks, you made me smile
(Cheering!)

(My WP topic ban would theoretically allow me to comment on your talk page there, but I'd rather not push it.)

The Cold fusion article process is totally crazy. It's claimed ''There are no reports from "secondary peer reviewed publications about the excess heat-helium correlation and x-rays". We cover the subject adequately.'' There are plenty of such reports, I won't list them here, but you can find heat/helium reports at Cold_fusion/Excess_heat_correlated_with_helium/Sources. I'm not expecting that you intervene in editing there, but it might help in understanding to know that the editor who made that claim has specifically removed at least one of these sources, so he knows they exist.

For a long time, the main library (by far) of by-permission preprints of most papers in the field, lenr-canr.org, was globally blacklisted, by request of one of the set of editors who have been sitting on the Wikipedia article, and the renewal of my topic ban on Wikipedia was based on my successful request at meta to lift that blacklisting. (I was allegedly too argumentative, though, in fact, it's quite obvious that if I hadn't been, the request would not have been granted. I was laying out the evidence, so I could then file a meta RfC if necessary. The blacklist admins knew that, and don't want an RfC, it would crimp their style, they are basically allowed to do Whatever They Please otherwise. I've worked on the blacklist problem for years, I know these admins and can sometimes cooperate with them....) Attempts to link to that library as an external link from Cold fusion, it clearly satisfies external link policy, were eventually removed (it was there for years), and an attempt to link to the Wikiversity resource was likewise recently reverted. "Self-published" was claimed -- which wouldn't be a reason for an EL! If, however, WV resources are "self-published", then every link on Wikipedia to another Wikipedia article would be to a "self-published" page. They were applying sourcing standards to external and inter-wiki links. Whatever it takes to keep it out.

It's very clear: there are editors on WP who do not want Wikipedia guidelines on sourcing and the ArbComm decision on fringe science to be implemented with cold fusion. The editor in question was topic banned on anything to do with fringe science in that decision, and Cold fusion is under discretionary sanctions as a result of my later case, but AE is useless if nobody is left who both understands the situation and is allowed to intervene.

I abandoned the effort and have not appealed the ban simply because it had all become too much work. One article isn't worth it. I can build resources on Wikiversity, and can work with skeptics, etc., without all the huge conflict. Some argument, for sure, but not the total waste of time that is Wikipedia process, slogging back and forth.

Anyway, thanks for making me smile. Ura Ursa may or may not be a sock, but these people will assert it and act on it without proof, they've done it many times, basing sock ID on POV, which then becomes a POV ban. Very similar to the whole Climate Change mess there, and some of the same people have been involved. --Abd 04:17, 27 December 2010 (UTC)
 * What a mess. —Caprice 05:38, 27 December 2010 (UTC)

Noob Question on Classification
Thank you for your welcome and invitation to ask questions, which I belatedly found today. Hope you don't regret it.

I'm working on a collection of lessons, currently linked from my user page (in the nav box at the bottom--the link is "What the Bible Says"), in a field where a similar resource already exists (Bible survey). My stuff is aimed at a secondary or adult education audience, and the existing material seems decidedly post-secondary. Is there room for both, and when the time comes how will I integrate my lessons?

Thanks again. Exfilia 18:57, 2 October 2010 (UTC)

How to Add Categories
Hi, I'm writing to you as a custodian (I think that's the term). I would like to add a category to the non-formal learning hierarchy, and possibly a sub-category. The major category would be 'careers and employment.' Obviously once I've done that I need to be able to mark articles so that they appear in the new category. Would you please point me in the right direction or towards someone else who might have the time to do so? Thanks! BillBell 18:21, 15 December 2010 (UTC)

Please ignore my request. I think I've found what I need. Thanks anyway. --BillBell 20:23, 15 December 2010 (UTC)

And thanks for the welcome! BillBell 16:19, 16 December 2010 (UTC)

[[media: Egm6341.s10.mtg35.djvu | Page 35-1]]

OPTIMAL CONTROL : Hermite-Simpson Algorithm: Local coordinate for $$\displaystyle [t_i,t_{i+1}]: $$ s such that

$$\displaystyle t(s)= (1-s)t_i + st_{i+1} $$ $$\displaystyle (Eq. 1) $$

$$\displaystyle s=0\; \Rightarrow \; t(0)=t_i $$ $$\displaystyle s=1\; \Rightarrow \; t(1)=t_{i+1} $$

$$\displaystyle z(s)= c_0 + c_1s + c_2s^2 +c_3s^3 \;\; s\in [0,1] $$ $$\displaystyle (Eq. 2) $$

At the end points, $$\displaystyle t_i\; and\; t_{i+1} $$ enforce compliance with the differential equation.

Collocation:

$$\displaystyle \dot{(z_i)} = f_i:= f(z_i,t_i)$$ $$\displaystyle (Eq. 3) $$

$$\displaystyle \dot{(z_{i+1})} = f_{i+1}:= f(z_{i+1},t_{i+1})$$ $$\displaystyle (Eq. 4) $$

Question: What happened at other points in $$\displaystyle [t_i,t_{i+1}] $$

[[media: Egm6341.s10.mtg35.djvu | Page 35-2]]

In general, $$\displaystyle \dot{z_t} \neq f_t \;\; t\in (t_i,t_{i+1}) $$ $$\displaystyle (Eq. 1) $$

Recall that z(t) is an approximation and not an exact solution. i.e, z(t) does not satisfy the differential equation at all points but only at certain discrete points.

Continuing from [[media: Egm6341.s10.mtg34.djvu | Page 34-4]], $$\displaystyle z(s) = \sum_{i=0}^{3} c_i s^i = \sum_{i=0}^{3}\underbrace{N_i(s)}_{Basis function} \underbrace{d_i}_{DOF}$$ $$\displaystyle (Eq. 2) $$

$$\displaystyle d_1=z_i\;\; d_2=\dot{z_i}\;\; d_3=z_{i+1}\;\; d_4=\dot{z_{i+1}}$$ $$\displaystyle (Eq. 3) $$

$$\displaystyle \dot{z} = \frac{dz}{dt} = \underbrace{\frac{dz}{ds}}_{z^'} \frac{ds}{dt}$$ $$\displaystyle (Eq. 4) $$

From (Eq.1) of [[media: Egm6341.s10.mtg35.djvu | Page 35-1]] , $$\displaystyle \frac{dt}{ds} = t_{i+1}-t_i = \underbrace{h}_{Step-size} $$ $$\displaystyle (Eq. 5) $$

$$\displaystyle \therefore \frac{ds}{dt} = \frac{1}{h} $$

[[media: Egm6341.s10.mtg35.djvu | Page 35-3]]  Goal: To find $$\displaystyle {[c_i]} $$ in terms of $$\displaystyle {[d_i]} $$

Using (Eq.2) and (Eq.3) in [[media: Egm6341.s10.mtg35.djvu | Page 35-2]], $$\displaystyle d_1 = z_i = z(s=0) = c_0$$ $$\displaystyle (Eq. 1) $$

$$\displaystyle d_2 = \dot{z_i} = \dot{z}(t=0) = {z_i}^' \frac{1}{h} = z^'(s=0)\frac{1}{h}$$ $$\displaystyle (Eq. 2) $$

$$\displaystyle z^'(s) = \sum_{i=1}^{3} ic_is^{i-1}$$
$$\displaystyle (Eq. 3) $$

$$\displaystyle z^'(s=0) = c_1$$
$$\displaystyle (Eq. 4) $$

Similarly,

$$\displaystyle d_3 = z_{i+1} = z(s=1) $$
$$\displaystyle (Eq. 5) $$

$$\displaystyle d_4 = {z_{i+1}}^' \frac{1}{h} = z^'(s=1)\frac{1}{h} $$
$$\displaystyle (Eq. 6) $$

$$\displaystyle \begin{bmatrix} 1 &0 &0  &0 \\ 0 &1  &0  &0 \\ 1 &1  &1  &1 \\ 0 &1  &2  &3 \end{bmatrix}

Using (Eq.5) on [[media: Egm6341.s10.mtg36.djvu | Page 36-3]] and Simpson's rule, we obtain (Eq.3) on [[media: Egm6341.s10.mtg36.djvu | Page 36-3]]

Assume $$\displaystyle z_i $$ is known. Hence find $$\displaystyle z_{i+1} $$ using (Eq.3) on [[media: Egm6341.s10.mtg36.djvu | Page 36-3]]

1. $$\displaystyle f_i = f(z_i,t_i) \; \rightarrow $$ Can be computed.

2. $$\displaystyle f_{i+1} = f(\underbrace{z_{i+1}}_{unknown},\underbrace{t_{i+1}}_{known}) \; \rightarrow \;Unknown\;\;(t_{i+1} = t_i + h). $$

3. $$\displaystyle f_{i+\frac{1}{2}} = f(\underbrace{z_{i+\frac{1}{2}}}_{unknown},\underbrace{t_{i+\frac{1}{2}}}_{known}) \; \rightarrow \;Unknown\;\;(t_{i+\frac{1}{2}} = t_i + \frac{h}{2}) $$.

Time-stepping algorithm: $$\displaystyle z_{i+\frac{1}{2}} = z(s=\frac{1}{2}) = g(z_i,z_{i+1}) \rightarrow $$ $$\displaystyle (Eq. 1) $$

$$\displaystyle z_{i+1} = z_i + \underbrace{\frac{h/2}{3} \bigg[f_i + f(g(z_i,z_{i+1}),t_{i+\frac{1}{2}}) + f_{i+1} \bigg]}_{Non-linear function in z_{i+1}}$$ $$\displaystyle (Eq. 2) $$

$$\displaystyle \Rightarrow F(z_{i+1}) = 0 \rightarrow $$ Non-linear algebraic equation in $$\displaystyle z_{i+1} $$ $$\displaystyle (Eq. 3) $$

The installation problems of Inkscape and TexText under Windows 7 and Windows XP, and their solutions, are documented here.

= Install Inkscape =

Go to the inkscape official download Page to download the Official Release Packages.

Update on 2012.12.30: The installation of Inkscape (e.g., under Windows 7) is very easy. Just download Inkscape version 0.48.4 for Windows 32 bit and install. The installation will take a few minutes, be patient... That's it. On the other hand, this installation does not have TexText (latex equation fragments in svg figures) yet; see further below.

What is Inkscape?
Inkscape is a vector graphics editor application.
 * Inkscape (wikipedia)
 * An Inkscape introduction and tutorial video; see also further below for more turorials

What is the SVG format ?
Scalable Vector Graphics (SVG) is a family of specifications of an XML-based file format for describing two-dimensional vector graphics.
 * SVG (wikipedia)
 * Understanding SVG with Inkscape (video, 1hr)

= Install Textext =

To use textext on Inkscape, some Latex programs are needed. Just follow directions on the below tutorial webpage.

http://pav.iki.fi/software/textext/

or a newer version

https://bitbucket.org/pitgarbe/textext

These instructions have been tested for the installation of Inkscape 0.48 (current stable version as of Jan. 2011) with MikTex 2.9 and Textext on a Windows XP OS, and work beautifully.

For an installation of Inkscape and Textext using Windows 7, see below.

Note

A Latex program is already installed?
 * Any Latex program can work with Inkscape. (2012.12.30: Need to check this statement; we only tested with MikTeX 2.8 and 2.9)

A different version of the Inkscape?
 * There is NO big difference for textext between textext version 0.4.4 and the previous version of textext, see the textext webpage.

= Known working versions under Windows XP =

Below is a known working combination of versions of Inkscape and Textext under Windows XP.

 * Operating System: Window XP Professional 2002
 * Inkscape 0.47 (old version; the current version as of 06/11/2011 is 0.48.1-2; see the section below of the installation issues of this version)
 * Textext-0.4.4.exe from http://pav.iki.fi/software/textext/
 * Installed MikTex, Pstoedit, Ghostscript, and the Textext installer (textext-0.4.3.exe) (works for Inkscape 0.46 and 0.47) as documented in http://pav.iki.fi/software/textext/

= Install Inkscape 0.48.1-2 and Textext 0.4.4 under Windows 7/XP (Jun 2011) =

 Update on 2012.12.30:  See also the installation guide textext.pdf, which can be accessed through the web site Designing Attractive Presentations by James Davis.

Under Windows 7/XP, after a "regular" installation of Inkscape and Textext as shown above, you may encounter the following error message:

From the info in the Textext discussion on "textext.py:55:", the above warning message is usually found in Windows 7 environment. The same error also occurred under Windows XP for Inkscape 0.48.1-2 and Textext 0.4.4.

If you want to use Inkscape 0.48.1-2 and Textext 0.4.4 together in Windows 7/XP, you need to go through a few more steps to install Textext 0.4.4 than with older versions of Inkscape (e.g., 0.46, 0.47) under Windows XP.

The 11 steps below are recommended as a solution; follow the steps in numerical order (the first 10 steps were originally published in the Textext discussion on "textext.py:55:"); you need to have Administrator privilege.

 * 1. Install the Latex distribution for Windows MiKTeX 2.8 or 2.9. Sometimes, it is better to install MiKTeX 2.8, instead of the newer version 2.9, so that other software that works with MiKTeX 2.8, but not with 2.9, can be used (e.g. latexeqedit-0.4 worked with MikTeX 2.8, but not MikTeX 2.9, even though more recent version of this software may work with MikTeX 2.9).

 * 2. Install Inkscape, e.g., inkscape-0.48.1-2.exe.

 * 3. Install pstoedit; download the [setup binary pstoeditsetup350.exe]; during the set up, click to select to install all components

 * Note that if you installed pstoedit in a drive different from the default drive C:, you need to include the path to pstoedit in the PATH environment varialble; see further below.

 * 4. Install GPL Ghostscript for 32-bit machine, i.e., gs900w32.exe, for pstoedit to find this binary automatically without having to change the PATH environment. With the version for 64-bit machine, you may need to change the PATH environment for pstoedit to find the binary. This advice / warning was given in TeXPPT.

 * Note that if you installed the 32-bit version of gs9.02 in a drive different from the default drive C:, you need to include the path to gs9.02 in the PATH environment varialble; see further below.

 * 5. Install TeXtext extension for Inkscape (textext-0.4.4.exe)

 * 6. Download the zip file libxml2-2.7.7.win32.zip, extract (right click on zip file, select "Extract All...", the folder C:\Users\your_username\Downloads\libxml2-2.7.7.win32\ will be created), and copy the contents to the folder C:\Program Files (x86)\Inkscape\libxml2-2.7.7.win32\. Another way without extracting the zip file is to double click at the zip file to enter the contents of the zip file to copy the folfer libxml2-2.7.7.win32\ to copy to C:\Program Files (x86)\Inkscape\libxml2-2.7.7.win32\.

 * 7. Go to Fixing textext on Inkscape for Windows to download the zip file site-packages.zip - THIS LINK DOES NOT WORK!. Extract the folder site-packages\ from the zip file site-packages.zip (right-click on the zip file, select "Extract All..."), then copy the contents of the folder site-packages\ to the folder C:\Program Files (x86)\Inkscape\python\Lib\ (it is fine if some files were overwritten -> OK!). If there is the folder C:\Program Files (x86)\Inkscape\python\Lib\site-packages\, then just copy the contents of the new folder site-packages\ into this existing folder.  Under Windows 7, if the folder C:\Program Files (x86)\Inkscape\python\Lib\site-packages\ does not exist, it is possible to create this folder by moving the new folder site-packages\ into C:\Program Files (x86)\Inkscape\python\Lib\; it is also possible to copy the contents of the new folder site-packages\ to the folder C:\Program Files\Inkscape\python\Lib\.  Alternatively, if one does not have access to the zip file site-packages.zip, as mentioned at the beginning of this paragraph, one can perform the following steps ("dirty fix"):
 * 7.1. Download Python 2.6: python-2.6.msi. Then install it.
 * 7.2. Rename C:\Program Files\Inkscape\python to C:\Program Files\Inkscape\python_backup
 * 7.3. Copy your C:\Python26 to C:\Program Files\Inkscape
 * 7.4. Rename C:\Program Files\Inkscape\Python26 to C:\Program Files\Inkscape\python
 * 7.5. Restart Inkscape This is a very dirty fix, though, and is the same as Solution 2 in Step 11 below.

 * 8. Install GraphicsMagick-1.3.12-Q8-windows-dll.exe. Search and copy the files CORE_RL_magick_.dll and CORE_RL_Magick++_.dll files (in the folder C:\Program Files (x86)\GraphicsMagick-1.3.12-Q8\) into your pstoedit folder C:\Program Files (x86)\pstoedit\.

 * 9. Edit the file C:\Program Files (x86)\Inkscape\share\extensions\textext.py.

 * -> It is much easier to use an editor with syntax highlighting and with line numbers listed; go to the Notepad2 web page to download notepad2 4.2.25 (x86) editor for editing *.py file.

 * -> Change line 55 to "import os, sys, tempfile, traceback, glob, re, copy" without the quotes, i.e., remove "md5" between "re" and "copy".

 * -> Add line 56 "import hashlib" without the quotes

 * 10. Ensure that the PATH environment variable contains the following paths:

 * C:\Program Files\Inkscape\libxml2-2.7.7.win32;C:\program files\GraphicsMagick-1.3.12-Q8;C:\Program Files\MiKTeX 2.9\miktex\bin

 * Under Windows 7, there are two ways to access and edit the PATH environment variable. The simplest way is to click Start, then type "environment variable" in the search box, then select "Edit the system environment variables" to bring up the "System Properties" window.  Another way to access the "System Properties" window is click at Start, then right click at the link "Computer" on the right column, then select "Properties" to bring up the Control Panel, "System and Security", and "System"; click at the link "Advanced system settings" on the left column to bring up the "System Properties" window.  To access the environment variables, select the "Advanced" tab (which shows up by default), click at the button "Environment Variables" (at the bottom) to bring up the "Environment variables" window; there are two subwindows, one for the user, and one for the "System variables".  In the "System variables" subwindow, scroll down to find the "PATH" or "path" environment variable; click to highlight the PATH environment variable, then click Edit to begin to edit this environment variable.
 * In my Windows 7 installation, the PATH environment variable looks as follows:

 * C:\Program Files\Inkscape\libxml2-2.7.7.win32;C:\program files (x86)\graphicsmagick-1.3.12-q8;C:\Program Files (x86)\MiKTeX 2.8\miktex\bin;C:\Program Files (x86)\Common Files\ArcSoft\Bin;C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\Windows\System32\WindowsPowerShell\v1.0\;C:\Program Files (x86)\Common Files\Roxio Shared\DLLShared\

 * Under Windows XP, open the Control Panel, click Performance and Maintenance, then System to bring up the System Properties window; click at the Advanced tab, then click at the "Environment Variables" at the bottom; in the "System Variables" box, highlight the variable "Path", then click Edit.

 * In my Windows XP installation, the PATH environment variable looks as follows:

 * F:\Program Files\pstoedit;F:\Program Files\gs\gs9.02\bin;F:\Program Files\Inkscape\libxml2-2.7.7.win32;f:\program files\graphicsmagick-1.3.12-q8;F:\Program Files\MiKTeX 2.8\miktex\bin;C:\Program Files\Common Files\ArcSoft\Bin;C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem;C:\Program Files\Common Files\Roxio Shared\DLLShared;F:\Program Files\MATLAB\R2009a\bin;F:\Program Files\MATLAB\R2009a\bin\win32

 * Note that I installed all additional programs (Inkscape, pstoedit, gs, GraphicsMagick, MiKTeX) in drive F:, instead of in drive C:, and thus I needed to add to the PATH environment variable the paths to these programs, in particular the paths to pstoedit and to gs. Without adding the paths to pstoedit and to gs as done above, I got the following error message:

 * 11.In Inkscape, to have latex formulas, invoke the TeX text feature by clicking at the link "Extensions" in the top taskbar, then select "Tex Text".

 * -> You may then see the error message below:

Even though there may pop up this error message, you still can see the typed formula shown in your Inkscape edit area. In order to get rid of this problem, there exists two solutions: Solution 1: Simpler than Solution 2 below. Found this solution in this web page as follows:
 * -> Remove the drvmagick.dll file from the pstoedit directory, i.e.,C:\Program Files (x86)\pstoedit\

Solution 2: See the "dirty fix" in Step 7 above.
 * -> Download the setup binary for python version 2.6 (python-2.6.msi), and execute this setup binary to install python 2.6 in the default folder C:\Python26\.

 * -> next, copy all files from the folder C:\Python26\ to the folder C:\Program Files (x86)\Inkscape\python\ (overwrite existing files).

= Install Inkscape 0.48.1-2 and Textext 0.4.4 under Windows 8/7/XP (Jan 2016) =

These instructions have been tested with Inkscape 0.48 for Windows. Install every program either in 32 bit version or 64 bit.

1. Install a Latex distribution, eg. MikTex

2. Install Pstoedit. Remove or rename the drvmagick.dll file from the pstoedit directory.

3. Install Ghostscript

4. Download and run GraphicsMagick installer, try Q16 version, if doesn't work then Q8.

5. Download and run Textext installer v0.4.4. The installer will install necessary library files from PyGTK in addition to the Inkscape extension. The library files go under python\Lib\site-packages in the Inkscape directory.

6. The TexText inkscape extension has to be updated manually by a fixed version because of a library issue. Go to "C:\Program Files\Inkscape\share\extensions" and change the textext.py file according to these instructions.

7. Check also that you can run pdflatex.exe (from Miktex) and pstoedit.exe on the command prompt (cmd.exe). If not, add the directories where these files reside to your PATH environment variable.

8. If so far you used a 32 bit version of all software, then download and install PyGTK (like pygtk-all-in-one-2.24.2.win32-py2.7.msi).

9. If so far you used a 64 bit version of all software, there is no pre-built pygtk 64 bit package. The simplest solution is to replace the python installation used by Inkscape with another more complete one like Anaconda Python. Download it and install it in C:\. Then go to your Inkscape installation folder and change "C:\...\Inkscape\python" to "C:\...\Inkscape\python_bak". The last step, it to make in the command line (cmd.exe called with the administrator privileges) a hard link to your python installation with the MKLINK command. Example: mklink /h /j "C:\Program Files\Inkscape\python" C:\Anaconda

= Install Inkscape 0.91 and Textext 0.5 under Windows 8/7/XP (Jan 2016) =

These instructions have been tested with Inkscape 0.91 for Windows. Install every program either in 32 bit version or 64 bit.

1. Install a Latex distribution, eg. MikTex

2. Install Pstoedit. Remove or rename the drvmagick.dll file from the pstoedit directory.

3. Install Ghostscript

4. Download and run GraphicsMagick installer, try Q16 version, if doesn't work then Q8.

5. Download and run Textext installer v0.5. The installer will install necessary library files from PyGTK in addition to the Inkscape extension. The library files go under python\Lib\site-packages in the Inkscape directory.

6. The TexText inkscape extension has to be updated manually because of a library issue. Go to "C:\Program Files\Inkscape\share\extensions" and update the code of textext.py to handle the change introduced in Inkscape 0.91. According to this note, replace the call to inkex.unittouu with self.unittouu. This affects lines 299 and 300 of the source code, as described here. Then it works for inkscape 0.91, even 64 bit.

7. Check also that you can run pdflatex.exe (from Miktex) and pstoedit.exe on the command prompt (cmd.exe). If not, add the directories where these files reside to your PATH environment variable.

8. If so far you used a 32 bit version of all software, then download and install PyGTK (like pygtk-all-in-one-2.24.2.win32-py2.7.msi)

9. If so far you used a 64 bit version of all software, there is no pre-built 64 bit pygtk package. The simplest solution is to replace the python installation used by Inkscape with another more complete one like Anaconda Python. Download it and install it in C:\. Then go to your Inkscape installation folder and change "C:\...\Inkscape\python" to "C:\...\Inkscape\python_bak". The last step is to make in the command line (cmd.exe called with the administrator privileges) a hard link to your python installation with the MKLINK command. Example: mklink /h /j "C:\Program Files\Inkscape\python" C:\Anaconda

I wrote a personal inkscape manual when I started to learn inkscape back in Jan 2008; some of the procedures documented there may be no longer valid, e.g., the use of textext.

Tips on using Inkscape
$$\Rightarrow$$ Change the color of different features: Use arrow tool on the left tool bar to select the feature you want the color of which to be change,using shortcut"Shift+Ctrl+F" or in the "Object" menu choose the "Fill and Stroke", then a user interface will pop out on the right of text area in Inkscape. You can change the color of filling and stroke or the stroke style.

$$\Rightarrow$$ Change the size of the drawing canvas: In the "File" menu, select the "Document Properties" or use shortcut "Shift+Ctrl+D", then a user interface will pop out. You can modify the page size by selecting the default size, A1, A4 etc., or inputting the width and height by yourself.

$$\Rightarrow$$ Use grid to help you draw: While drawing, you can turn on the "Grid" in the "Edit" menu to help you manage the scale of different features.

$$\Rightarrow$$ Use snap to assist you to select input point: While drawing, you can turn on the "Snap" in the "Edit" menu to assist you to choose input point.

For more tips, you also can see Basic Tutorial or Advanced Tutorial.

= Using textext within Inkscape =

If textext was installed well, Tex Text menu item is on the Inkscape

Input statements are the same with Wiki. Only difference is math and /math comments. $ is using instead of math and /math comments on the Inkscape

Setting the preamble file for textext
In the above figure, you see that there was no preamble file. What is the preamble, and what is it used for ?

For example, if you want to have the boldface Greek symbol omega, e.g., in [[media: EGM6341.s11.TEAM1.WILKS_EC23_3.vql.svg | this figure]], you would use the following latex code

and the command  requires the latex package   to be loaded into latex via the preamble.

To create the preamble file, e.g., named "textext.preamble.tex", you can use a text editor (e.g. notepad++, gvim) to create a text file with that name, and containing the following lines:

When the textext window pops up (as shown in the previous section), click at the "Preamble file" bar to search for the path to the preamble file "textext.preamble.tex".

After the above, the boldface Greek symbol omega should come out correctly in inkscape.

Using the above method, you can add more packages into the preamble file for textext, depending on your need.

Actually, in [[media: EGM6341.s11.TEAM1.WILKS_EC23_3.vql.svg | the figure]] mentioned above, I also used the txfonts package in addition to the above two packages so to create a slightly different font (darker, with thicker lines) than the default latex Computer Modern font:

=More on SVG file= Import "SVG" file into Word2007 document (The quote sign means the file isn't svg file anymore after you insert it into Word document)

In Microsoft Office Word, we can insert pictures of varies kind of format, like jpeg, bmp, jif, png, etc. Unfortunately, the SVG file can't be directly imported into Word document. There are two ways we can manage this issue.

Solution 1: Drag and Drop

Firstly, Open the SVG file in Internet Explorer (I also have tried Firefox, it doesn't work as in Internet Explorer), and the Word document which you want to add this SVG file to. Drag the SVG file and drop it at the location where you want to put this file in the Word document. Then everything is done. You can modify the "inserted" figure as what you can do for other normally inserted files. The picture may be changed to some other acceptable format after the drag and drop, since the picture isn't scalable anymore.

This method is only tested on the 2007 version of Word. For older or newer version, you may also try this method to see whether it works.

Solution 2: Converting file format

Method 1: Open svg file in Inkscape, use "Save as..." in the "File" to save the picture in png format. You also can save it as .ps, .emf, .wmf formats that the Word document accepts.

Method 2: Open svg file in Inkscape, use "Export Bitmap" in the "File" to store the picture in bmp format.

After converting the svg format into any format that Word can accept directly, you can follow the routine we usually do to insert pictures into Word document.

Export SVG file in MATLAB

Usually, we can export the plot in MATLAB by using "Save..." or "Save as..." command into varies kind of picture format, like jpeg, bmp, jif, png, etc, but not SVG. How can we save the image drawn in MATLAB as SVG file?

Solution:

Go to this website SVG Export of Figures, and download the plot2svg.m file first on the right column. (You also can download other related files on this page which are unnecessary here.) Put this plot2svg.m file into the folder where you installed MATLAB, like C:\Program Files\MATLAB\ in my computer. Or, you can save this .m file wherever you want, then in the MATLAB interface select "File"$$\rightarrow$$ "Set Path" $$\rightarrow$$ "Add Folder" $$\rightarrow$$ (Select the folder where you have put your downloaded plot2svg.m file) $$\rightarrow$$ "Save" $$\rightarrow$$ (the folder containing the .m file is added to the MATLAB path) $$\rightarrow$$ "Close".

Every time you want to save your figure as SVG file, you need to use plot2svg function at the end of your plot function. The format is as following: Figure(...); title('...'); xlable('...'); . . . plot(...); plot2svg('put the name of the svg file here');

After running the MATLAB code, the svg file is automatically saved in the default MATLAB directory in the "Documentation" folder if you have never changed the "Start in" path. On windows system, you can find your "start in" path of your MATLAB by right click the MATLAB icon, select "Properties" (Last one), then the property interface will pop out, and you can find the "start in" path. Follow this start in path, you can find where the svg file is stored.

Question: Why did Simpson's rule pop-out in HS algorithm? (Why not some other rules) Ans: Recall that Simpson's rule can integrate exactly polynomial less than or equal to 3. Refer the theorem on [[media: Egm6341.s10.mtg14.djvu | Page 14-1]] and it's geometric interpretation on [[media: Egm6341.s10.mtg13.djvu | Page 13-3]].

HS Algorithm: Collocation(enforcing compliance with the differential equation at 2 end-points and mid-point);Use cubic Hermitian interpolation Upon enforcing compliance with the differential equation at mid-point (closing gap), then Simpson's rule naturally pops out since it can exactly integrate a cubic polynomial with 3 points.

Sindarin Lesson 1

"Quotes" are English [Brackets] are Sindarin

The Definate and Indefinate Articles
There is no actual word that explicitly means "A" or "An", instead the words are implied. [edhel] means "elf" or "an elf" [aran] means "king" or "a king" To say "the" the word is [i] before singular nouns or [in] before plural nouns. Before consonants, the article changes the sound, but this will not be discussed until Chapter 3. [i edhel] "the elf" [in edhil] "the elfs" [i ion]   "the son" [in ion]  "the sons"

The Genitive
To say that A owns B you can simply juxtapose the two words, [B A]. This is often done with names, but can always be done even with no names. [aran Gondor]  "king of Gondor" [hîr Imladris] "lord of Rivendell (Imladris)" [ion aran]     "son of a king" [ion in erain] "son of the kings" [cabed i aras] "leap of the deer" You can also insert the word [en] before singular nouns or [enan] before plural nouns. They are often definate, so "the" can be implied. It CAN be used with names, but this is rare. [cabed en aras] "leap of the deer" [ion en aran]  "son of the king" [aran en noeg] "king of the dwarves" [aran Ennorath] "king of Middle Earth" (Ennorath is grammatically plural) [nan] and [nia] can be used instead of [en] and [enan] respectively, but this is rare. Before consonants, [nan] and [nia] change the sound, but this will not be discussed until Chapter 3.

Your account will be renamed
Hello,

The developer team at Wikimedia is making some changes to how accounts work, as part of our on-going efforts to provide new and better tools for our users like cross-wiki notifications. These changes will mean you have the same account name everywhere. This will let us give you new features that will help you edit and discuss better, and allow more flexible user permissions for tools. One of the side-effects of this is that user accounts will now have to be unique across all 900 Wikimedia wikis. See the announcement for more information.

Unfortunately, your account clashes with another account also called KingElessar. To make sure that both of you can use all Wikimedia projects in future, we have reserved the name KingElessar~enwikiversity that only you will have. If you like it, you don't have to do anything. If you do not like it, you can pick out a different name.

Your account will still work as before, and you will be credited for all your edits made so far, but you will have to use the new account name when you log in.

Sorry for the inconvenience.

Yours, Keegan Peterzell Community Liaison, Wikimedia Foundation 23:41, 17 March 2015 (UTC)

 * Thanks for your message, Michelle. I see now what you want - a separate page for your e-portfolio. Wiki convention is that this would go into a user sub-page. Harrypotter's suggested link above is spot on - I've also adjusted the e-portfolio link on your user page to go to a subpage. Hope this makes sense. -- Jtneill - Talk - c 03:12, 27 August 2010 (UTC)

Image:Thaipusam&me.jpg
Hi! I noticed that you uploaded Image:Thaipusam&me.jpg for your ePortfolio - I hope that you got a good grade for your work. :) However, I noticed that when you uploaded it you did so with a license that prohibits commercial use. Unfortunately, on Wikiversity, such images are fine, but only if they are used in articles with a fair use rationale. I'm not sure if you still want to use the image in your portfolio, but as that isn't an article, technically the photo can't be left there. On those grounds I've had to remove that photo for now and nominate it to be deleted, along with the picture of Peter Ekman, but if you would like to change the license or otherwise provide a reason for keeping it that would be fine. If you need any assistance just ask - I'm very happy to help out in any way that I can. - Bilby 17:00, 19 October 2011 (UTC)

Wikiversity:Request custodian action/Archive/7

Vandalism tools
I, and it looks like other custodians, haven't quite as present around here lately. I've noticed that anonymous IP vandals seem to be doing more editing before we are responding. One today made 30 (?) or so edits. Fortunately Adambro was around to mop up. S/he makes some excellent suggestions here User_talk:Adambro, basically (paraphrasing): -- Jtneill - Talk - c 13:30, 2 July 2009 (UTC)
 * 1) Non-admin rollback scripts: How can we get one of the non-admin rollback scripts to use here because it is a bit tedious having to go through all the diffs clicking undoing after checking I'm not reverting back to another edit by the vandal.
 * 2) AbuseFilter: It doesn't appear that WV has the AbuseFilter extension installed. That might help with the vandalism. Obviously not going to stop everything, or you risk inconveincing genuine users, but could perhaps be a useful tool.

 * Any reason not to just give him the whole kit and kaboodle? He's an admin on several other projects, so shouldn't need much in the way of mentoring. If we have trustworthy folks around doing RC patrolling, seems easy enough to just give them the tools -- especially since most of the sysops here aren't around much any more (me included). Not much sense playing whack-a-mole endlessly when a block button would be more efficient. --SB_Johnny talk 14:57, 2 July 2009 (UTC)

 * I'd support Adambro for tools. But, we might also want to look into opening rollback to more people the way that wp did a while back.  --mikeu talk 15:13, 2 July 2009 (UTC)

 * I've nominated Adambro: Candidates for Custodianship. -- Jtneill - Talk - c 17:56, 2 July 2009 (UTC)

Removing explicit content
Some of the spam recently was the "insert explicit image from commons" type e.g., on talk pages. At least one user has contacted me about that. What's the process for requesting oversight of such edits? And could we perhaps add that to Vandalism and/or Managing vandalism? -- Jtneill - Talk - c 07:01, 5 July 2009 (UTC)

 * As a result of the recent repeat vandalism I added a couple of images to MediaWiki:Bad image list. This prevents them from appearing in the page history. (see  for example) For oversight you can go to irc channel #wikimedia-stewards on freenode.  (requests are not made on wiki to prevent vandals from evading the response and to limit the number of people who notice the edit)  Type "@steward oversight request" (again, don't post links to a page needing oversight in the channel itself, wait for a steward to private message you)  I'm not sure that I would request oversight of a large number of pages with just an explicit image.  This is more for someone posting personal information, threats, etc.  You could also delete the page, and then restore all versions except the one with the image edit.  This would hide the edit from anyone who does not have tools. For urgent advice, drop by #wikiversity-en and there will probably be someone there who can offer some solutions or workarounds.  --mikeu talk 11:51, 5 July 2009 (UTC)

 * I doubt this would qualify for oversight... generally that's only used for cases when private information is improperly disclosed and needs to be hidden from all users (including sysops). You could delete that version instead.
 * Last time I got oversight for something the steward mentioned that it causes slight problems with the database. Darkcode would probably know more about that.
 * BTW, there are a lot of explicit images on commons, so trying to badlist them all would take quite some effort :-). --SB_Johnny talk 12:27, 5 July 2009 (UTC)

 * Agree, I would not ask for oversight for something that is only vandalism. Jtneill, the guidelines at Oversight list "non-public personal information" and "potentially libellous information" as approved use for oversight.  Another use might be to hide a username that contains libel.  Deleting the individual edits from the revision history that contain the image is better, but can be a pain if there are many pages.  That is why I Bad_image'd those two that were used by a serial vandal.  --mikeu talk 15:31, 5 July 2009 (UTC)

Advanced Projects in Chemistry
I have quite a few questions - 1.I have submitted 3 other Chem Projects on Wikiversity AP Chem projects and now they are lost 2. What criteria should my writing conform to to get Wikified-I have quite a few projects of use to contribute 3.Where do I submit my writing each time? Sincerely Anjali (anjali@podar.net) recently registered the account "Anjali" on Wikiversity from the IP address 202.159.225.252.

 * It looks like you have made contributions to the page Category:Advanced Placement and Pre-AP Chemistry projects. Are these the lost projects that you are talking about?  The material at that page should get moved a new name, because the Category: pages are use to organize materials and text should go to pages with names in main space like Advanced Placement and Pre-AP Chemistry projects.  --mikeu talk 12:39, 25 October 2009 (UTC)

Advanced Projects in Chemistry
Yes that is the lost content-is it wikified? What is thequality check for it to be wikified? I know that JTNeill moved my content to Advanced Projects in Chemistry- how do those link with this sitehe created? But I am still at loss or thoroughly confused on the entire logical process of how this is working. Cud u please explain? My main goal is to contribute content/publish towards the Wikiversity After content is uploaded -editing- section wise delegation of content-uploading of content how is all this process happening? SincerelyAnjali 14:55, 28 October 2009 (UTC)Anjali
 * Dear Anjali! Just a few quick points that might help you to get a clearer picture:

 * Go through FAQ/Editing, at least the first part. It explains how to use links within Wikiversity.
 * About the previous remarak of mikeu: Just compare the category Category:Advanced Placement and Pre-AP Chemistry projects and Category:Chemistry. The latter one is, how the category pages should look like: minimum text and listing all relevant categories and pages.
 * Next time you just hit "edit" link near the sub-heading, you dont need to create another section for the same thing. --Gbaor 13:51, 29 October 2009 (UTC)

There are unfortunately other users "Ocj" please change mine to Epid, thank you, regards Ocj 18:41, 5 December 2009 (UTC)

"Founder" actions probably need to be undone
See the log for details. I don't see any prior discussion of either the deletion or the block. Unless I'm missing something or there are strong objections, I intend to undo both. The project doesn't seem to actually be out of scope, and I don't see anything "disruptive" in the user's contributions. --SB_Johnny talk 10:52, 13 March 2010 (UTC)
 * I'd strongly advise against anyone undoing these actions. Jimbo isn't daft. He knows exactly what he is doing. Suggest discussing it with him before taking any action as he has requested; "please do not unblock without consulting with me". The reason he has the "Founder" status is to allow him to retain a degree of control over the WMF projects so he can, as he considers appropriate, use those rights if he feels it is in the interests of the project or WMF projects more broadly. Adambro 12:46, 13 March 2010 (UTC)
 * Sorry, but after looking further into it, both the deletion and the block were completely inappropriate. I'll open a discussion about it on WV:CR, but for now I'm undoing the actions for the following reasons:
 * The project does seem to fall within Wikiversity's scope, as established by precedent in numerous and exhaustive discussions surrounding most of the other pages in the Wikimedia Ethics project. As this page was primarily simply an investigation into breaching projects that have taken place on Wikipedia, it is clearly within the scope of Wikipedia studies.
 * Unlike the materials in that project that were found to be objectionable, this was because they were perceived to be attacks or inappropriate criticism of individual Wikipedia editors. This page does not do that.
 * Since the page seems within scope and I didn't see anything in User:Privatemusings' other contributions, the block was inappropriate as well.
 * The only "background" to this seems to be this note on Jimbo's WP talk page, which is insufficient reason for the actions he performed here.
 * Again, I will open a community review in a few minutes and link to it here and on his talk. --SB_Johnny talk 12:57, 13 March 2010 (UTC)
 * So have you discussed this with Jimbo first? If not I feel you've made a mistake here to reverse his actions. Jimbo is a member of the Board and so has the power to take actions such as this as he feels appropriate. I appreciate your significant concerns that he has taken these actions but discussing these concerns with him would be the right course of action. Adambro 13:17, 13 March 2010 (UTC)
 * I'll leave him a note on his WP talk and hopefully he'll join us on Wikiversity:Community Review/Wikimedia Ethics:Ethical Breaching Experiments. It can't reasonably be discussed if the page is deleted, and the main contributor is unable to participate. --SB_Johnny talk 13:19, 13 March 2010 (UTC)
 * I previously gutted the main content of the project and warned Privatemusings about continuing down that path. I don't really see any need for the Founder's actions or any need to undo it as the the problematic aspects of the project were already discontinued. I made it clear that discussions on breaching and the rest would be okay as long as there was no advocacy towards or aiding of violations. Ottava Rima (talk) 20:02, 13 March 2010 (UTC)
 * Understood, and thanks for your efforts thus far. Jimbo kinda upped the ante though, so we need to deal with the hand we're dealt at this point. --SB_Johnny talk 22:49, 13 March 2010 (UTC)

Problems in creating account
I tried signing up with a new account, but the system tells me the two usernames I tried are already taken (so I assume that I have a username already). But if I try to get a new password it says "no such username", which is weird. It can't be both!

Error on Main page
Turns out you don't have a editprotected so I guess I just post here. Problem outlined at Talk:Educational Picture of the Day. Rambo's Revenge 23:22, 30 March 2010 (UTC)
 * Thx and was fixed, Erkan Yilmaz uses the Chat (try) 11:26, 31 March 2010 (UTC)
 * I've imported editprotected from WP so we now have a template for such requests. It will add the page to Category:Wikiversity protected edit requests which perhaps should be listed somewhere prominently for custodians to be aware of. I'm not sure where though. Adambro 12:52, 31 March 2010 (UTC)

 * This wasn't set up right so I've fixed the categorisation. As for listing it prominently I've put it at the top of this page and it will turn red when there are oustanding requests. Feel free to move it, but this seemed the most logical place to put it. Thanks, Rambo's Revenge 13:34, 13 June 2010 (UTC)

Page doesn't exist text
Where is the text that appears if a page doesn't exist stored? There is an extra square bracket to be removed - e.g. see any redlink - Help:Gallery2... Actually, the text I'm talking about only appears if you type a non-existent page in directly - try http://en.wikiversity.org/wiki/Help:Gallery2 - it doesn't appear when clicking on a red link. Not sure why. It's good info that appears when putting in a page name - how could we make it appear when clicking on any red link? -- Jtneill - Talk - c 01:16, 10 April 2010 (UTC)

 * I am glad you like it :-)
 * I have removed the extra square bracket.
 * I can make red links display the same or similar text too, if that is wanted. Using the same amount of space though will push the textbox down.
 * -- dark lama  01:30, 10 April 2010 (UTC)

 * Yes, I think it would be worth adding. On Wikibooks they have a lot of text when clicking on a red link, but it does go straight to the edit box, with the standard text above. Not sure if this is default or something they've done. -- Jtneill - Talk - c 01:50, 10 April 2010 (UTC)

 * The textbox has focus, in my web browser at least I still have to scroll down to bring the entire textbox into view. -- dark lama  02:01, 10 April 2010 (UTC)

 * Looks good I think. Was wondering about the sister project links though - they are generic. What do you think about customising them to search each sister project for PAGENAME? -- Jtneill - Talk - c 02:23, 10 April 2010 (UTC)

 * What's focus? In WB using firefox I get taken straight to the edit box when clicking on a red link. On WV I start at the top of the page. Not a big deal since even the new WV text is quite short, but I'm curious. -- Jtneill - Talk - c 02:26, 10 April 2010 (UTC)

 * Focus in the context of a textbox means the textbox is ready to receive any text you type without having to press the tab key to cycle through or click the mouse button over the textbox first. -- dark lama  02:32, 10 April 2010 (UTC)

 * Aha, yes, I see. So, how is focus controlled? -- Jtneill - Talk - c 02:38, 10 April 2010 (UTC)

 * I cannot see anything that Wikibooks could be doing to make that happen. -- dark lama  02:44, 10 April 2010 (UTC)

check your site
I was able to modify the text on your site...may want to look into that. There are (edit) links that allowed me to make changes and save.....
 * That's correct - you can edit - its a wiki. -- Jtneill - Talk - c 22:05, 12 May 2010 (UTC)

creating a new account
I'm trying to create an account. The "fuzzy" code letters pop up and I type them in, but I keep getting a message that there is missing information or incorrect code. I don't get it, I'm sure I'm spelling the words right. What am I doing wrong? 68.225.14.236 02:43, 13 May 2010 (UTC)
 * Were your letters the right case? Sometimes a capital "i" looks like a lowercase "L". You can refresh and get another set. Ottava Rima (talk) 03:38, 13 May 2010 (UTC)

Rollback request
Did some Recent Changes Patrol here and found the lack of rollback quite irritating, took much more work to go back through six IP vandalisms in sequence. I'd appreciate having the rollback privilege, I have it on en.wiki. One more question: this was a short IP range, where would I request a temporary rangeblock? Thanks. (For reference, see, all edits were vandalism.) --Abd 01:31, 24 May 2010 (UTC)
 * Looking around, it seems that rollback may not be a separated privilege here, as on en.wiki, it's only given with custodianship? I could be helpful, I suppose, with custodianship, I doubt I'd wreck the place.... --Abd 01:47, 24 May 2010 (UTC)
 * If you want custodianship, apply and I'll vouch for you if no one else will. Ottava Rima (talk) 03:42, 24 May 2010 (UTC)
 * Thanks, Ottava. I'll go for it. I cannot promise to be always active, but at least I can contribute. The process here of allowing adminship on a trial basis is a great idea, if removal is easy, as it should be, especially for admins in a trial period. --Abd 16:41, 24 May 2010 (UTC)
 * Resolved. I was granted probationary custodianship, see Candidates for Custodianship/Abd. Thanks, Ottava. --Abd 16:48, 13 June 2010 (UTC)
