StackOverflow/StackExchange: two queries to help me improve my questions and answers

Posted by jpluimers on 2014/09/05

On the StackExchange network, I try to keep track of the questions I asked, and answers I gave in order to see if they need follow up.

For instance, questions with answers that have no accepted answer usually indicate there is room for improvement.

On my own questions, it means I could accept an answer, or give out more information on how to better answer that question.

On mu answers to questions from others, it might mean I need to improve my answer, or comment on his question to explain it better.

The first category can be queried easily by the built in search capabilities:
http://stackoverflow.com/search?q=user%3ame%20is%3aanswer%20hasaccepted%3ano

The second category requires the Stack Exchange Data Explorer (SEDE) to execute some SQL:
My answers to questions that have no accepted answer – Stack Exchange Data Explorer.

  • Replace the ‘me’ with your StackOverwlow user ID
    (for StackOverflow.com, you can get that from http://stackoverflow.com/search?q=user%3ame as it will be listed in the search box there)
  • replace stackoverflow with a mnemonic obtained from the main SEDE page (click on the icon you are interested in, then copy that part into the query)

Note some questions (like Wiki: Current state of the art of Delphi 3rd party TCP/IP components libraries – Stack Overflow) are not suited to have one ‘best’ answer.

Note the SEDE can be addictive. If it is starting to become that way, perform a Jon Skeet comparison.

Note the SEDE data is usually at least a few days older than the live data.

Where to watch for StackOverflow / StackExchange downtime status: @StackStatus, @TechCrunch, @HNTweets

Posted by jpluimers on 2014/02/17

Basically, stackstatus.net is not actively updated when severe things like DDoS happen. So the best way to be kept up to date is watch these links:

Windows Timer Resolution: Megawatts Wasted (via: Random ASCII)

Posted by jpluimers on 2013/07/11

Don’t increase your Windows Timer Resolution. And keep an eye on programs that do:

Raising the Windows timer frequency is bad. It wastes power and makes your computer slower. Routinely doing this in all sorts of programs that end up sitting idle for hours really needs to stop.

You can use ClockRes to monitor the time resolution and what programs changed it.

c# – What’s the hardest or most misunderstood aspect of LINQ? – Stack Overflow

Posted by jpluimers on 2013/05/07

It is such a pity that StackOverflow is not the place any more for questions like these:

c# – What’s the hardest or most misunderstood aspect of LINQ? – Stack Overflow.

These questions and answers historically got me most of the insight from SO.

Alas, no more.

c# – What are your thoughts on Raven DB? – Stack Overflow

Posted by jpluimers on 2013/01/17

Too bad the new StackOverflow rules actively discourage the kind of open questions like “c# – What are your thoughts on Raven DB?“.

They are being closed as “not constructive by casperOne♦ Nov 29 ’11 at 5:25”, which is a shame as these kinds of questions often reveal very valuable and balanced answers.

Right now I’m resarching what RavenDB could mean for storing documents. And yes, I know about the RavenDB licensing model: free for open source, pay for commercial use.

Repeating characters into strings in C# and Delphi (via: .net – Best way to repeat a character in C# – Stack Overflow)

Posted by jpluimers on 2012/06/26

Switching back and forth between mainly Delphi and C#, sometimes it is hard to remember which idiom works best in each environment.

Recently, I had to dupe a lot of tab characters for some Tab-Delimited interface to an archaic system.

I remembered the Delphi idiom: use the DupeString function as about Delphi explains (yes, I know: it dupes more than just characters).

In C#, these work best for me:

Small code sample of the first way (thanks CMS):

static string Tabs(int n)
{
    return new String('\t', n);
}

Oh BTW: I have reduced my StackOverflow presence. It looks like the success of StackOverflow made them instantiate many moderators. A lot of those moderators work under the mantra “we follow the rules strictly, and favour punishment over encouragement” (some  even talk about “changing heritage“). That’s a real pity, as I see a lot of StackOverflow users get scared by the very active downvoting, question/answer closing and even deletion of material that is in essence valuable, if it were edited up a bit. Deleting content is always bad, as it increases the link rot that StackOverflow are trying to prevent in questions/answers as per their FAQ. Links are the foundation of the web.

Alas, devoting real attention to the quality of StackOverflow requires putting real energy in it, which for some of the moderators seems to be too much to ask.

Funny how StackExchange, StackOverflow, ServerFault, SuperUser and differ in indicating their site outage “We are Offline”

Posted by jpluimers on 2012/02/18

Tonight these most StackExchange sites have maintenance, including their bogs and meta sites (the chat sites like http://chat.stackoverflow.com/ are on-line). I checked these to be off-line, most of the bigger table below are offline too.

Later I will amend this post with the HTML and try to get some site previews too.

A bit later I got this kind of message from Chrome, that tried to protect one of the sites:

Error 139 (net::ERR_TEMPORARILY_THROTTLED): Requests to the server have been temporarily throttled.

Note that http://askubuntu.com/ is up and running :) Read the rest of this entry »

FlightAware > BOE236 787 drawing a Boeing logo on FlightAware

Posted by jpluimers on 2012/02/11

The start of the thread comments:

Karsten Liljegren about 24 hours ago

I was one of the Boeing pilots on this record setting flight. 19 hours and 22 minutes block to block (and 10408 Nautical Miles)… The longest ETOPS endurance test flight ever!

Air Traffic Control was fantastic and very accommodating. – Thank you!

The airplane performed flawlessly. As a matter of fact – we didn’t even top off the fuel tanks.

Boeing Test and Evaluation

A few days after it flew from KPAE to KBFI, it took a 19+ hour ETOPS test flight from KBFI to KBFI and adding a new drawing to the list of previous drawings by other aircrafts.

Some links:

Jon Skeet and Tony the Pony on Vimeo

Posted by jpluimers on 2011/10/26

This is from 2009, but still sooooo funny.

Lets use these 2 thumbs as parity bits.
I should have done this with pounds and pounds.
Why doesn’t John Skeet does never sleep.
No, you can’t have Visual Studio … yes telepathy is fine.

And more great quotes, sample code and experiences (like the Turkey Test) in this wonderful presentation by Jon Skeet and the famous Tony the Pony

Hilarious, and true :)
