== Shortest video game ==
== Putting an App Icon on the Home Screen ==
[[A Short Hike]] (as the name suggests) can be beaten within a few hours. What other games are like that? [[User:JuniperChill|JuniperChill]] ([[User talk:JuniperChill|talk]]) 19:18, 19 August 2025 (UTC)
I have a Samsung Galaxy J7, running Android version 8.1.0. What I want to do is to add another application icon to the home screen. The icon for it is currently in the Applications window that I can open by clicking on the Applications window icon, but I want to display it on a page of the home screen. At this time the application is Spotify, and I want to be able to launch Spotify and Maps conveniently at the same time. However, I think that my question is more general, and is how to put an icon for an application on the home screen that is installed but isn't on the home screen.

:You should be able to move the app to your home screen by dragging it. Long-press if necessary or tap, hold, and move your finger; the home screen(s) should appear and allow you to release your finger and drop the app onto it. [[User:Elizium23|Elizium23]] ([[User talk:Elizium23|talk]]) 01:18, 25 February 2020 (UTC)
:Yep, long press and hold the icon in the start menu (I guess that's what's called the Applications window). After a second or two the home screens should appear in the background, then you can drag the icon where you want it. You can also long press an empty space on the home screen and you'll get a popup menu allowing you to add stuff like app shortcuts.

: "50 Games Like" aims to be a weighted-category based games recomendation engine. Just based on ''A Short Hike'', it lists [https://www.50gameslike.com/games-like/a-short-hike these games]. But that's based on ''all'' the categories ''A Short Hike'' is in ("cute", "adventure", "exploration", etc.). If you just want "short" games, you click on just the category button and it gives you [https://www.50gameslike.com/best-games-by-type/short short games in all genres] (which aren't like ''A Short Hike'', except in shortness). Subjectively, it looks more useful than Steam's recommendation engine, which gives me some fairly bonkers suggestions ("you liked FTL, so you might like Doom Eternal"). -- [[User:Finlay McWalter|Finlay McWalter]]'''··–·'''[[User talk:Finlay McWalter|Talk]] 19:40, 19 August 2025 (UTC)

:Finlay's answer is excellent, but I can't help mention that the original ''[[Portal (video game)|Portal]]'' game is both famously short and considered one of the best games of all time.

I need to traverse a large tree with a depth-first search. I need an estimate of the number of nodes to get an idea if it is feasible to do it. What I have in mind is to start the search but at each node, select one edge at random. Keep track of the branching factor at each level. Then repeat this maybe 10<sup>5</sup> times and get an average branching factor at each level. Then multiply the branching factors to get an estimate of the total number of nodes.

==Short descriptions, Wikidata, and SQL/SPARQL==
Hi, I would like to know how to search for items on Wikidata with descriptions longer than, say, 150 characters; I've noticed that the very long ones tend to be unsuitable for use as short descriptions on Wikipedia.

:::There is probably no index on the term length, i.e. it's doing a linear scan. Your options: 1) create index or ask someone to create one (it will be even slower than the linear scan, but will allow future such queries to run fast); 2) get your timeout increased or get someone with higher limits to run the query for you; or 3) download the db to your own machine and run the queries on your own db instance. The last is the best if you want to muck with the data a lot, but of course it's more work and takes resources (your own machine or VM, basically).

== What does ''illegal'' mean in the context of HTML? ==
I'm a CS dropout with a bit of programming experience but not much. It's also been years since I coded anything. I consider myself pretty good at working out the logic side of things but I usually get stuck when trying to figure out the best way to do something or if there is a standard way of achieving a certain result. I want to get back into coding by starting a web development project and already I am unsure how to achieve a desired result.
To use it in a sentence (no pun intended), it's illegal to place a div inside an inline tag. – [[User:MrPersonHumanGuy|MrPersonHumanGuy]] ([[User talk:MrPersonHumanGuy|talk]]) 01:15, 2 September 2025 (UTC)
A basic website usually has for example a logo/home page link, a navigation bar, a footer, and the content of the particular page. So a basic way of doing this would be to include the logo, navigation bar, and footer on each page. However, for a (dynamic) site that is constantly adding content this seems less than ideal.

So I was thinking maybe of having a template php page which includes the logo, nav bar, etc. but then would also have some php code that would include the required content.
I don't want to be given the answer (at least for now) as I'd rather figure it out for myself but am I along the right lines? If not maybe a bit of a nudge in the right direction. What sort of problems would this approach present?

:Are you using a PHP-dependent content management framework or system such as [[Drupal]] or [[WordPress]]? If not, than now is perhaps a good time to switch to [[Django]]/[[Python (programming language)|Python]]. The learning curve is not very steep, there are excellent tutorials, the community is very helpful to novices, and in the end you will probably enjoy the greater flexibility. --[[User talk:Lambiam|Lambiam]] 08:01, 2 March 2020 (UTC)
:You can use the include function in PHP to include whatever you like. So, you can create a file that makes the navigation bar, such as "nav.inc". Then, include it where you want it: include("nav.inc"); You can have files that include other files. For example, all the stuff that comes before the main contant might be in a file named "top.inc". That file includes the header, styles, css, title bar, nav, etc... Then, everything after the content might be in "bottom.inc". So, your web page becomes include("top.inc"); include("mycontent.inc"); include("bottom.inc");. The content one is where you handle dynamic content. Normally, you query a database, get content, and format it properly. But, you could just as well include a text file.

==How do I eliminate this standard error?==
Here is a kata/programming practice exercise that I recently did:
https://www.codewars.com/kata/55b3425df71c1201a800009c/train/python
Here is my own solution to this kata:
<pre>
def findMedian(list):
list = sorted(list)
length = len(list)
if length % 2 == 1:
halfLen = int(length / 2)
median = list[halfLen]
elif length % 2 == 0:
num1 = int(length / 2) - 1
num2 = int(length / 2)
median = int((list[num1] + list[num2]) / 2)
return median
def findRange(list):
list = sorted(list)
range = list[-1] - list[0]
return range
def findMean(list):
list = sorted(list)
sum = 0
for i in range(0,len(list)):
sum += list[i]
i += 1
mean = sum/len(list)
return int(mean)
def convertFormat(num):
num = int(num)
hours = int(num / 3600)
minutes = int((num % 3600) / 60)
seconds = ((num % 3600) % 60)
return format(hours,'02d')+"|"+format(minutes,'02d')+"|"+format(seconds,'02d')
def stat(strg):
lisst = strg.split(', ')
lyst = []
for item in lisst:
lyst.append(item.split('|'))
numSec = []
for i in range(0,len(lyst)):
numSec.append([int(lyst[i][0])*3600, int(lyst[i][1])*60, int(lyst[i][2])])
numSecTotal = []
for i in range(0,len(numSec)):
numSecTotal.append(numSec[i][0]+numSec[i][1]+numSec[i][2])
numSecTotal = sorted(numSecTotal)
formattedMedian = convertFormat(findMedian(numSecTotal))
formattedRange = convertFormat(findRange(numSecTotal))+" "
formattedMean = convertFormat(findMean(numSecTotal))+" "
str = "Range: "+formattedRange+"Average: "+formattedMean+"Median: "+formattedMedian
return str
</pre>
This website actually accepted my solution as valid--which is why this solution of mine (by Futurist110, aka myself) is visible here:
https://www.codewars.com/kata/55b3425df71c1201a800009c/solutions/python/all/newest
However, when I clicked on the "Train Again" button and attempted to once again submit this solution with minor modifications, I got this error message in spite of my program passing all of the tests for it on this website:
<pre>
STDERR
Traceback (most recent call last):
File "main.py", line 75, in <module>
randomTests()
File "main.py", line 73, in randomTests

numSec.append([int(lyst[i][0])*3600, int(lyst[i][1])*60, int(lyst[i][2])])
ValueError: invalid literal for int() with base 10: ''
</pre>
What exactly in this program do I actually need to fix in order to eliminate this error message--and just how exactly do I fix the relevant part of this computer program of mine? Any thoughts on this? [[User:Futurist110|Futurist110]] ([[User talk:Futurist110|talk]]) 22:53, 2 March 2020 (UTC)
*It looks like you are passing an empty string to the int() function, maybe because of badly formatted input data. Rather than try to debug it for you, I'll suggest a way to debug it yourself: put try/except around the line where the error is happening, and print the relevant values in the event that the exception triggers. So in this case, replace line 41 with:
<syntaxhighlight lang="python">
try:
numSec.append([int(lyst[i][0])*3600, int(lyst[i][1])*60, int(lyst[i][2])])
except ValueError as e:
print (e, i, lyst[i])
raise
</syntaxhighlight>
Use the printed info to either figure out what is wrong, or figure out what other info you need to diagnose the error, then modify the program again to get the additional info. It will often take quite a few iterations of that to diagnose a bug. Debuggers can avoid some of that, but print-based tracing is something every programmer has to do some of the time.
Unrelated: I notice in your findMean function, you sort the list unnecessarily. I'd have just written sum(list) / len(list). [[Special:Contributions/173.228.123.39|173.228.123.39]] ([[User talk:173.228.123.39|talk]]) 01:58, 3 March 2020 (UTC)

== Place that pairs in-demand tasks with learning ==
Dear volunteers,
I am starting a project. The fundamental principle behind the project is that highest quality education is available online, and it is not being utilized to its full potential.
I want to make a place where concrete things that need to be done will be matched to the learning path towards skills required to get them done.
This learning path will be accompanied by freely available online resources.
Sites like upwork exist, but they merely present the things that need to be done. They are not learner friendly. You need to have already established knowledge in order to participate.
What I want is a place with a higher focus on learning. So, instead of only presenting a task that needs to be done, every task would have an automatically generated learning
path attached. Furthermore, each user would have a profile. As the user learns, the profile gets updated. The profiles would show what the individual has learned, and would serve as means of certification.
Two other students are working on this along with me. The project is in the planning and prototyping stage.
I have 3 questions.
1. Does a place doing anything akin to this already exist?
2. We have nothing in terms of financial or mentorship support. I understand that we would need to work for it, but are there any opportunities to get any sort of support? (We are from Croatia, if that means anything)
3. Do you see any major pitfalls that would make the type of thing I described impossible?
Thank you for your time.
