About this portal[edit]

The "Portal:Computer science" is a collection of hundreds of special (non-article) Wikipedia pages (with prefix "Portal:") that attempt to present an organized view into thousands of articles about the general subject of computer science. There are over 540 portals on other subjects (see general description: Wikipedia:Portal). This portal was begun in June 2006, but improvements are always welcomed, within the current structure, as it evolves. Although the portal pages are designed to help navigate into article groups, readers can still use the Wikipedia search option (at page left) to hunt articles by any words used inside an article. -Wikid77 (talk) 14:28, 8 February 2008

Portal image[edit]

Perhaps this portal can be given Image:Computer.svg (example at right) as an image. --User:AlastairIrvine 10:58, 3 May 2007 (UTC)

sounds like a good idea.Thea10 (talk) 15:59, 5 August 2013 (UTC)

Network Layer Service Model[edit]

This looks like it needs an article to go with it there's only a table on the page. The links almost all point to disambiguation pages. There is in sufficient context for me to determine the meaning of the abbreviation's. In fact thats how I found it in the first place. Also I am considerings a speedy delete nomination if it can't be expanded.Phatom87 (talk contribs) 16:24, 17 January 2008 (UTC)

I found serval articles related to the subject and have moved this to template space under the same name. Additional I managed to decipherer must the links and they now point to the appropriate articles. Phatom87 (talk contribs) 17:46, 22 January 2008 (UTC)

Retrofit topic headers[edit]

08-Feb-2008: There hasn't been much discussion here over the past 2 years, so I just grouped the older topics using level-1 headers as "Topics from 2007" (etc.) to emphasize age of topics. Older topics might still apply, but using the tactic of yearly headers to note the age helps avoid rehashing old news, without archiving any ongoing issues. -Wikid77 (talk) 14:28, 8 February 2008 (UTC)

About: About this portal[edit]

08-Feb-2008: I have retrofit the short topic "About this portal" near the top of the discussion to orient new readers to the concept of the portal (in case they miss "What is a portal?" on the overview page). That orientation blurb precedes the long discussion topics, and it alerts readers that thousands of articles have been linked from these computer-science portal pages, to give readers some idea of how many related pages they face. -Wikid77 (talk) 14:28, 8 February 2008 (UTC)

WikiProject Java and Portal[edit]

Hi guys! We just opened the Java portal for business and would appreciate if you could put a link to it in the 'Related portals' section of your CS portal. Thanks in advance! --  Alain  R 3 4 5

Topic for 2011?[edit]

This is a very useful portal, but the top "selected information", like the bio and selected topic doesn't change much, or perhaps at all?

Is there some mechanism to have it change automatically? Like some sort of link specifiying picking a random article with tags of "computer science" and "people"? — Preceding unsigned comment added by HacksawPC (talkcontribs) 03:00, 20 November 2011 (UTC)

This is sad, but if you look at the sidebar there's a link that says Help. I typed in "random" in the search and filtered by templates and it appears there are a few options:

--OMouse (talk) 11:08, 20 November 2011 (UTC)

Okay, I just woke up properly...you cannot have the selected article page point to a random article and you cannot automatically change it. The best we can do is use the Template:Selected article and document the process of updating the selected article. Automating the process could be done with a Wikipedia bot. The other nice thing is that we now know how to add random quotes and pages so that the frontpage can change a little bit at least. --OMouse (talk) 11:34, 20 November 2011 (UTC)

You could use Template:Random portal component to pick from a collection of numbered sub-pages. See Portal:Science, for example, which uses it to display a randomly-selected article and picture. This gets you frequent updates with no maintenance. -- John of Reading (talk) 12:37, 20 November 2011 (UTC)
Cool, I'm playing with this a bit to see if I can get it right. HacksawPC (talk) 06:01, 22 November 2011 (UTC)
Looks good! -- John of Reading (talk) 14:28, 23 November 2011 (UTC)
Thanks! I'm going to be able to add "Wiki Hacker" to my resume soon. :) HacksawPC (talk) 14:38, 23 November 2011 (UTC)
One thing is obvious, the actual collector page could be much simpler, it's lots of repeated semi identical tags. HacksawPC (talk) 14:38, 23 November 2011 (UTC)
Yes, I've just replaced its content with the {{Numbered subpages}} template. -- John of Reading (talk) 14:51, 23 November 2011 (UTC)
Ah, nice. HacksawPC (talk) 15:16, 23 November 2011 (UTC)

Degree Userbox[edit]

Is there a userbox for users that have a computer science degree? Allen (talk) 19:15, 3 March 2012 (UTC)

There are some computer-related degrees among the examples at Wikipedia:Userboxes/Education#Qualifications, or you can use the {{userbox}} template directly as I have at User:John of Reading/Userboxes. -- John of Reading (talk) 22:05, 3 March 2012 (UTC)

Still needed?[edit]

Does a portal like this still need to exist? It's rarely updated which isn't useful if a portal is meant as an exploration point.--OMouse (talk) 02:32, 19 March 2013 (UTC)

Welcome! Are you interested in helping to keep it updated? Technical 13 (talk) 20:55, 9 April 2013 (UTC)

IP[edit]

After Ipv4 we directly jump to IPv6 , where is IPv5 ? — Preceding unsigned comment added by 164.100.146.66 (talk) 11:33, 3 June 2013 (UTC)

Jython programming[edit]

I'm just researching some information on JES programming for my introduction to Information Technology at Melbourne's RMIT. I have unsuccessfully tried to source the answer elsewhere, if anybody can help me I would be much obliged, David Smith.



Why in Jython, (JES) do we get the output 3.9000000000000004 from 1.3 * 3?

and

Why do we get the output in Jython 0.3333333333333333 when we print 1.0 / 3?



Thank you.

David Smith. — Preceding unsigned comment added by Thesmithster (talkcontribs) 20:07, 3 December 2013 (UTC)

You are unlikely to get an answer by posting here. I suggest you ask again by posting at the Computing reference desk, where there are some volunteers eager to answer programming questions. -- John of Reading (talk) 20:12, 3 December 2013 (UTC)

Missing categories[edit]

Categories under Computer science are listed in alphabetical order and the current list ends with categories starting with the letter "O". It seems unlikely that there are no categories starting with "P" or "R", for example, so it seems like there may be a typo on this portal page?BradStewartCO (talk) 19:39, 18 July 2014 (UTC)

@BradStewartCO: Thank you for drawing attention to this. I had a look at Category:Areas of computer science and have added a couple more entries beginning with "T". The missing letters may just be a coincidence, but if there are important categories missing then feel free to add them. -- John of Reading (talk) 20:55, 18 July 2014 (UTC)
@John of Reading: Thank you for your speedy reply. I am unfortunately not sufficiently literate in Computer Science topics to pass judgment on the need for additional categories, so I can't really address the problem. I just thought there might be a simple typo involved that could be easily remedied. "Parallel computation" might be an example of another category worthy of substantial consideration at this level of the hierarchy. In any case, thank you again for your response.
