[edit] P-T Extinctions

In relation to your recent additions to Permian-Triassic extinction event, it may be useful to review Wikipedia:Neutral point of view which explains how Wikipedia articles should be written on subjects which may be disputed. Overall you did a very good job with the hydrogen sulfide material, but it would be useful to identify which parts of the chain of events are likely to be disputed by other scientists. Also, the tone of your writing skews a little bit towards saying "this is the truth" rather than "this is new plausible idea that has not yet been adopted by the scientific community as a whole".

Of course, these issues can occur even in the writing of experienced editors, so don't feel bad, but it is important to think about the best way to frame the scientific debate without trying to unfairly take sides in issues that the scientific community has yet to resolve.

Dragons flight 09:54, Jun 12, 2005 (UTC)

Thanks :) I am new here, and not a native English speaker (hence some rather rough formulations). Also, my historical expertise is not too high, I just found this when doing research for another article and found this theory missing here. If you are more familiar with the criticism of this theory, please do the edits. --Shaddack 11:04, 12 Jun 2005 (UTC)

[edit] Hydride

Hi Shaddack, thanks a lot for your work in the chemistry articles, excellent work! Would you mind having a look at the first paragraph of hydride? The definition there is confusing and seem self-contradictory. Cheers, AxelBoldt 23:13, 13 Jun 2005 (UTC)

[edit] SEU

Thanks for your contribs to the SEU stub. I haven't worked in the field for over a decade, so I appreciate others coming in and touching things up and/or fleshing out details. John Elder 3 July 2005 18:29 (UTC)

[edit] Depletion region and depletion zone

It might be more appropriate to put the merged version of these articles under depletion region, as that's by far the version I've seen most commonly (ref: Sedra and Smith, "Microelectronic Circuits", or check random papers at IEEE Xplore). It's also the term used most at p-n junction (though both are used there). --Christopher Thomas 19:38, 12 July 2005 (UTC)

Done as requested. Good idea. --Shaddack 20:39, 13 July 2005 (UTC)

[edit] Edit summaries

Hi Shaddack, I have noticed that you put a lot of work in enhancing chemistry-related pages. It would be a great help for other users watching those pages if you could provide a short summary of your edits, e.g. something like "+ [[Category:Solvents]]". Keep on, Cacycle 21:55, 23 July 2005 (UTC)

[edit] Red links

Thank you for your message about red links. I won't delete any more. Pintele Yid 09:50, 26 July 2005 (UTC)

[edit] Combat Information Center

Thanks for adding the article on Combat Information Center. It's been on my to do list for a while. You might try digging for a photo to add to the article at www.navy.mil in the photos section. I'll add some to the article later, when I have more time. I was once an OS and worked in CIC. --Durin 14:44, 27 July 2005 (UTC)

[edit]  :CueCat

Apologies... the one I got at RadioShack, the one which was mailed to me as a subscriber to Wired, and the one which was mailed to my wife for reasons that neither of us were able to determine all USB so I jumped to an inaccurate conclusion.

Pursuant to something or other in the licensing agreement, I forget what, I mailed one back to Digital Convergence with a polite demand that they pay for the cost of shipping it to them, and rather to my surprise they actually mailed me a check for the about-$2 shipping cost... Dpbsmith (talk) 19:34, 16 October 2005 (UTC)

[edit] CIC/NTDS images

Images a great. You tagged and sourced them properly. Nice work! For CIC, you might want to find a more current image of a CIC, not to replace the image that is on the article but to include a photo from 30 years on. There are many differences, and many similarities, as I suspect you know :) --Durin 15:14, 17 October 2005 (UTC)

[edit] Admin Nomination

You have been nominated for a admin position.

Please visit Wikipedia:Requests_for_adminship/Shaddack to indicate whether you choose to accept.  Ian13  19:35, 30 October 2005 (UTC)

[edit] Kraft vs. kraft

Shaddack, Thanks for adding a bit to the Kraft process article. I learnt a bit about this when I was working on sodium sulfate, but I wanted your opinion- should it be kraft or Kraft? I have seen both in the literature, do you have any idea which is the "correct" name? Thanks, Walkerma 04:29, 1 November 2005 (UTC)

I saw both versions as well. I do not have a solid opinion about this, nor I think it really matters at the end. I added a mention of this issue to the name paragraph of the article. Is it good enough to resolve or at least postpone the issue?

--Shaddack 05:20, 1 November 2005 (UTC)

That looks good now, thanks. Walkerma 20:39, 3 November 2005 (UTC)

[edit] Retene

That's a good picture you made for the retene article. -- Kjkolb 05:32, 6 November 2005 (UTC)

Thanks! If you want any other structure, let me know and I'll make it. --Shaddack 01:59, 10 November 2005 (UTC)

[edit] ethylene dichloride

Hi Shaddack, just to inform you: ethylene dichloride is always '1,2-dichloroethane. The 1,1-dichloroethane would be called ethylidene dichloride. As you were editing ethylene and not ethene, the use of the (in itself correct) systematic name could be considered inconsistent. Your choice. Wim van Dorst 11:10, 9 November 2005 (UTC).

Objection addressed, change deployed. Trivial name used as a link, systematic name mentioned in a bracket. Ethylene dichloride article amended with a link to ethylidene dichloride, with a mention it is a 1,1-dichloroethane. This should help non-native English speakers to cope better with English chem terminology. --Shaddack 02:01, 10 November 2005 (UTC)

• Good work, shaddack. Considering your interest and active contributions to chemical compound pages, perhaps you'd care to participate in the Chemicals wikiproject? We're working on getting a now fairly stable worklist to a higher standard (A-Class). That's where acetic acid, now up as featured article candidate (please support) also comes from. I'll pose a question there about the naming of these ethane derived articles, btw. Wim van Dorst 08:41, 10 November 2005 (UTC).

[edit] Your RFA

Hi! As you know, your RFA bid did not receive the required level of support and as a result I had to fail it. This does not mean that you cannot be an admin, you can try again later and see what went wrong in this RFA. Regards, =Nichalp «Talk»= 18:53, 9 November 2005 (UTC)

[edit] Relative Time

Hi,

I just thought I'd let you know that timezones are customizable on WIKIPEDIA, so when you quote a time, it doesn't necessarily mean anything... It might be better to refer to username or IP address instead of time... For example, this is how your revision line looked in my browser...

22:45, 15 November 2005 Shaddack (Rvv to version as of 00:09, 16 November 2005)

Which is to say "On November 15th at 10:45pm, I reverted the version to the one created on November 16th at 12:09am)

Because I have my timezone set to something other than yours, it just doesn't jive.

Thought you might like to know :O)

RickyWiki

P.S. I'm not an expert at time so if I'm wrong and just misunderstood your comment, please forgive me. I can't balance my chequebook either.

Argh. Good comment. However this may be a slight problem, as I date the reverts via a greasemonkey script that takes the date/time from the page, and there is no info about the editor name on the old-version-edit page. I think there is a solution, but let me think of it for a while... --Shaddack 05:11, 16 November 2005 (UTC)

Do you know the monkey who wrote the script? It would be enough to just have it append the editor's timezone to give a recourse for someone really wanting to figure out the stamp... just as in your paragraph above... :O)

Good idea. (Yes, I know that monkey pretty intimately, it's me.) Done so. Passing the version author name from history page to edit page still remains on my pending tasks list. --Shaddack 17:56, 22 November 2005 (UTC)

[edit] Acrylamide

Shaddack, I would be very grateful if you could please give an intelligent, rational and mature justification for reverting this page back to its old version. Please address the points I have mentioned in the Talk page. As you know, Wikipedia is freely editable so you do have to accept having improvements made to pages you may have written. Please put your rely on the Talk:Acrylamide Talk page. Thanks very much. Droid.

As per page history, I did not do any revert you seem to be complaining about. Please check the differences between the versions and see what I mean, as per talk page. --Shaddack 13:48, 20 November 2005 (UTC)

[edit] Ion implantation

I don't believe this falls under the category of thin film deposition, so I'm removing the category marker. If you disagree, feel free to leave a note on my talk page.--Joel 17:21, 20 November 2005 (UTC)

[edit] Terpenes

Hi Shaddack. I've noticed that you've added a couple of terpenes. I've been doing the same, in preparation for writing a much more complete article for terpene. I'll hopefully get to it soon. Perhaps this weekend. If you have any suggestions, please let me know. Edgar181 00:34, 24 November 2005 (UTC)

[edit] SiC, MoSi2

Do these really have a highly nonlinear PTC response? I thought that SiC, as a traditional semiconductor, was NTC. Only the titanates were mentioned in the class I took, but please correct me if I'm wrong. I'm also surprised to see SiC listed as a commercial heating element, and especially MoSi2: aren't these reserved for scientific/industrial furnaces?--Joel 05:38, 3 December 2005 (UTC)

Good question. Greenwood-Earnshaw: Chemistry of Elements specifies SiC as PTC, at least in my translation, however I won't bet my neck on it. --Shaddack 06:01, 3 December 2005 (UTC)

[edit] Corrosion in arc welding

Hi Shaddack, thanks for your contribution to arc welding. I have a few welding books but I couldn't find the information you added in any of them, so I thought I'd ask to see where you got it. References are really important, because at some point I'd like to make this article featured, and when that happens, all the parts of the article will need to be referenced. So if you could tell me the publication information of the book (as well as the page numbers) from which you got the information, that would be great, or you could add it yourself to the references section of the article. Thanks! --Spangineer^es (háblame) 16:23, 3 December 2005 (UTC)

Sensitivization of stainless steels: William Callister, Material science and engineering, page 569-571. Hydrogen embrittlement, I loaned out that book; I remember that electrodes for welding of stainless steels have to be moisture-proof packed, and have to be kept dry at all cases because of they otherwise tend to release hydrogen. I added some URLs referencing these. --Shaddack 16:59, 3 December 2005 (UTC)

[edit] pitting corrosion

I saw your additions to the article and it seems very good! Thanks, Sammo 21:07, 10 December 2005 (UTC)

[edit] Isotope geochemistry

Now that was weird. I made a couple of links to Isotope geochemistry and was looking at the article thinking about shifting the superscripts where they belonged. Wham - my browser crashed! And when I get back to the article they've shifted - magic! Thanks for reading my mind :-) Seems there's quite a bit more to do there ... always more to do. Vsmith 05:18, 18 December 2005 (UTC)

[edit] Yikes! I18N failures

You are correct! I have been using a Java tool called WikiLink [1] (that web site is down at the moment) to do some category renames where I need to do bulk updates. It works on almost everything else, but I will investigate. -- Fplay 17:19, 20 December 2005 (UTC)

[edit] Orphaned category

Hi there. I've been going through Special:Uncategorizedcategories, and I noticed you recently removed the category Palm oil from all of its parent categories, leaving it an orphan. In the future, can you please nominate unneded categories for deletion at Wikipedia:Categories for deletion or request that they be speedy deleted using the {{db}} template, whichever is appropriate? Thanks, SCZenz 03:53, 23 December 2005 (UTC)

Thanks, should do that next time. --Shaddack 03:55, 23 December 2005 (UTC)

Cool, thanks. This time, I went ahead and deleted it. ;-) -- SCZenz 03:57, 23 December 2005 (UTC)

[edit] Image:Photo-Polyswitch.jpg

Thank you for providing images to the commons. Please keep in mind that images and other files on the commons must be under a free license... (rest of image tagging request commented out for brevity) ... Thank you. -- gildemax 16:53, 24 December 2005 (UTC) --

Corrected. Please check. Any more outstanding problems? --Shaddack 18:03, 24 December 2005 (UTC)

Every thing is fine. Thanks a lot. ---- gildemax 20:59, 28 December 2005 (UTC)

[edit] dirty dozen

Hi Shaddack,

recently you drew structures of Aldrin, Dieldrin and other chemicals that belong to the "dirty dozen" of the Stockholm Convention. They are fine and I use them in de:Aldrin, de:Dieldrin, and de:Heptachlor. May I ask you to draw also the structures of Chlordan (1,2,4,5,6,7,8,8-Octachlor-3a,4,7,7a-tetrahydro-4,7-methano-indan), which has just one chlorine more than Heptachlor (1,4,5,6,7,8,8-Heptachlor-3a,4,7,7a-tetrahydro-4,7-methanoinden)?

Dieldrin (1,2,3,4,10,10-Hexachlor-6,7-epoxy-1,4,4a,5,6,7,8,8a-octahydro-1,4-endo-5,8-exo-dimethanonaphthalin) has got a stereoisomer called Endrin (1,2,3,4,10,10-Hexachlor-6,7-epoxy-1,4,4a,5,6,7,8,8a-octahydro-1,4-endo-5,8-endo-dimethanonaphthalin). Could you also draw that?

Thanks anyhow, de:User:Blech

Chlordane and endrin are drawn and uploaded to Commons. Article for endrin was written as it was missing. Please check if everything is correct? --Shaddack 21:48, 2 January 2006 (UTC)

Chlordane is correct, I am sure. Endrin and Dieldrin do have a slightly different spatial orientation than here [2]. I would say they are o.k., but stereo chemistry is not a strong side of mine. Thanks a lot, de:User:Blech 21:57, 3 January 2006 (UTC)

Redid the formulas of aldrin, endrin, and dieldrin, to have better conformation. --Shaddack 09:05, 4 January 2006 (UTC)

[edit] Pesticides

Hi, I started a few pages on insecticides recently. Do you want to draw the strucutres or would you like me to. Also do you think we should make a large single article on OP insectcides or do you think we should make lots of smaller articles on each OP ? Cadmium 21:06, 7 January 2006 (UTC)

Please let me know the list of the pages in need of a formula? Regarding OPs, I am in favor of a hybrid approach: a comparison page about the entire family and a quick comparison table, and detailed articles about each member. That way we can be detailed enough when needed, and at the same moment have a brief walkthrough of all of them in a single place. --Shaddack 23:01, 7 January 2006 (UTC)

I have made a start on the main page, I have included an example of a class of substances which were worked on by a german chemical company (either BASF or Bayer).Cadmium 16:06, 8 January 2006 (UTC)

[edit] VEIL - pointer to more detailed specifications?

Message to Shaddack, Response requested:

I have been communicating with Danny O'Brien at EFF about a hoped-for talk with the staff of Senator Gordon Smith, who will be sheparding HR4569 aka "The Digital Transition Content Security Act of 2005" xxxx2006 through committee. I am also hoping to talk to technical managers at local companies Tektronix and Grass Valley Group to see if I can get them to communicate their concerns to the Senator.

I have designed video analog to digital converter chips, and have 3 patents on the subject (Mea culpa!). Ultra high speed data converters are difficult enough to design and manufacture as it is - this bill will be the equivalent of requiring aircraft carrier decks for speedboats. Right now, I am attempting to do a paper design to estimate just how big the addition might be to a general purpose high speed digitizer.

You did a nice writeup on VEIL for Wikipedia, but your article, and the references it points to, do not mention signalling levels (in IRE luminance, or in volts, or ...) for the VEIL signal, nor is the Rights Assertion Mark format discussed. While I imagine you would have included that information if you had it, perhaps you can point me at a source of detailed specifications for this technology, and I can interpret it at the implementation level.

Keith Lofstrom keithl at keithl dot com Beaverton, Oregon

Response issued via email. My hat off re the patents. --Shaddack 23:02, 7 January 2006 (UTC)

[edit] Science articles

Excellent work on the science articles, Shaddack. :-) Kjkolb 10:38, 9 January 2006 (UTC)

[edit] Stub templates on virus articles

Hi, you created some good stubs on various viruses. Please be aware in future that there is a more specific template, {{Virus-stub}} which is more relevant for those articles than {{med-stub}}. There is a list of all the approved stub templates at Stub types. Thanks! Mushin^talk 16:45, 12 January 2006 (UTC)

[edit] Re Category:Anonymity networks

Excellent work. A lot of the anonymity-related articles were really badly categorized before, but your new articles seem well thought out, thanks. Haakon 22:31, 13 January 2006 (UTC)

[edit] Track (CD)

Hi Shaddack, looks like you were mid-sentence editing Track (CD) and forgot about it... interested in finishing it? Also, I have done a lot in the related articles, including a lot of merging. —Quarl ^(talk) 2006-01-15 12:18Z

[edit] Structure of Pentazole

Hi Shaddack,

Just to draw your attention to the chemical structure of Pentazole which you've added to the article on that topic - it looks like you've inadvertently uploaded the structure of pyrrole instead. Pentazole is a five-membered ring containing only nitrogen atoms (HN5 as the neutral species, if such a thing exists), while pyrrole contains four carbons and a nitrogen (C4H5N). -- Gustavus 17:29, 19 January 2006 (UTC)

OUCH! Corrected. --Shaddack 18:04, 19 January 2006 (UTC)

[edit] carotenoids

I'm new here, but I think you made an alteration to make this statement about carotenoids:

"The double carbon-carbon bonds interact with each other in a process called conjugation. As the number of double bonds increases, the wavelength of the absorbed light increases, giving the compound an increasingly red appearance."

I think, however, that it is inaccurate. As wavelength absorbed increases, a redshift in absorbtion, how can the compound have an increasingly red appearance? It seems like it should say increasingly blue appearance. Brianf711 19:10, 20 February 2006 (UTC)

I don't think I was the one who made the changes, on carotenoids the revision history related is this. Regarding the formulation itself, I am not really certain, it is too late here now. --Shaddack 05:54, 21 February 2006 (UTC)

[edit] Drawing organic compounds

Hi there. I notice that you have uploaded several organic structures, and wondered what software you use - as I would like to do the same. Cheers. Jeff Knaggs 16:02, 18 March 2006 (UTC)

(Sorry for late answer.) I essentially copied the setting of Cacycle, with some minor tweaks (copy/paste to IrfanView, then automated scaling down to 50% and conversion to PNG using netpbm utilities). --Shaddack 05:10, 23 April 2006 (UTC)

[edit] Wikics template

Hi Shaddack! Recently, I created a new template to indicate English Wikipedia users who also contribute to the Czech Wikipedia.

Template:User wikics

Feel free to add it to your userboxes if you like it (and if you actually contribute). Happy Easter. Daniel Šebesta (talk • contribs) 22:35, 14 April 2006 (UTC)

Thanks for letting me know! I contribute to the CZ one less than rarely, though. My ambitions are somewhat more global. Will keep this in mind in case my conditions change. --Shaddack 05:10, 23 April 2006 (UTC)

[edit] Wow!

Holy crap! Where did you find the information for all those compounds in article phosphor?!! really great, thanks! Perhaps you can verify/correct my guesses at the spectrum of the origin of the peaks in light from fluorescent tubes?[3]--Deglr6328 18:41, 22 April 2006 (UTC)

I took them from various manufacturers' webpages, and from an electrical engineer reference book. No clue if the spectrum is correct, but it looks plausible. We should write down how phosphors work on the atomic/lattice level... --Shaddack 05:10, 23 April 2006 (UTC)

[edit] Thanks for adding the links to the Sago mine story.

For a while, it seemed like I was working on it alone!--Beth Wellington 05:04, 28 April 2006 (UTC)

[edit] Category:Cellulose

Hi there. I have nominated Category:Cellulose derivates for renaming as Category:Cellulose. Feel free to comment here if you are interested. I'm contacting you because you created the original category. Mike Dillon 02:20, 2 May 2006 (UTC)

Do whatever you think is the best. The name of the category is not critical - the grouping of related things together is more interesting than nomenclature details of the group. Alternately, describing the category as "Cellulose, its forms and its derivates" could make things cleaner. --Shaddack 19:47, 2 May 2006 (UTC)

[edit] Image:Neutral red.png

The structure you drew for this compound seems to have a missing chloride ion. See here. Jeekc 05:29, 4 October 2006 (UTC)

I am aware of it. The chloride was considered unimportant, as it contributes only minimally to the chemical behavior and not at all to the color. The chemical can be quite as well a sulfate or acetate or any other suitable salt with just minimal difference of its properties, therefore I chose to omit the anion. --Shaddack 09:40, 4 October 2006 (UTC)
