@allquixotic, yes, what you said? Really? Your intent isn't to write 700 page textbooks? Who asked that? Me? I didn't really ask it to you! If my question seems to be wide, you have to respond widely, that's all! And do not come here, everytime, telling me that these or those ones are too wide as question to respond to! Just respond as wide as the question is, and don't be so squared, or you will have seriously problems in the future! Just decrease the quality of this question, who really cares about it? — Spiderpork8 mins ago
@Bob guy asks bad question -> posts in comments "why is this bad" (every single question he asks has a similar first comment) -> barlop says "it isn't bad, i love you" (or similar) -> techie007 says "it's bad, but..." -> back and forth -> i try to explain -> guy threatens me -> barlop agrees with me. in a nutshell.
this sums up the mentality of the OP in a nutshell (from another Q of his, which is also downvoted and closed):
Yes, I could have written what he has already done, of course, but I ask this question in this way to have many possible answers, many possible solutions. Why are you so squared? — Spiderpork22 hours ago
that's... just not how the site works
also, "squared" is apparently some Czech jargon of some sort (assuming his google.ch hugeurl indicates he's from there)
@allquixotic Well, many answers isn't necessarily bad. There's always going to be multiple solutions (especially with perl questions...). This just happens to be too open-ended.
@Bob programming questions are likely to have many solutions, but that isn't so common on SU, unless someone asks a subjective question. problem is, this isn't even a subjective question; it's an objective question, but it's asking for a very detailed account of a very broad topic area
@Bob also, is this a junior or senior level course?
if this course is at all higher level than sophomore, and he doesn't know how to read lines from a file, he should be barred from ever entering the software industry
Considering how late he seems to have started, perhaps he just didn't look at the assign specs.
Oh, not non-programming, just a simpler one.
> Only available to approved non-CSE/EET students (e.g.: Mechatronics). Such students should e-mail [email protected] before 28th March expressing their desire to work on a scale-down version of the programming assignment. Approved students will be e-mailed the alternate assignment specification.
I'm need to create .PDF from webpages, excel/word document and etc. How should I go about it? I used to use some software long time ago I just don't remember name of it and since there is so many to choose from I'd like to see recommendation from StackExchange community for open source PDF driver...
But it's the example TCP server code alongside the assign specs.
Here's the Java example code:
/*
*
* tcpServer from Kurose and Ross
*
* Usage: java TCPServer [server port]
*/
import java.io.*;
import java.net.*;
public class TCPServer {
public static void main(String[] args)throws Exception {
// see if we do not use default server port
int serverPort = 6789;
/* change above port number this if required */
if (args.length >= 1)
serverPort = Integer.parseInt(args[0]);
// create server socket
ServerSocket welcomeSocket = new ServerSocket(serverPort);
while (true){
@Bob anyone who is dumb enough to write new code like that for an application in 2014 should be fired before they finish writing #include <sys/socket.h>
well it's actually a lot easier to "come up with an application layer" (on top of TCP) in Java, and I can't see a justification for not at least using a friendly wrapper around TCP sockets instead of the godawful mess (and standards compliance mess) that is "libc"
there's a simple TCP listener in GLib. you could do that in "C" and it would be no conceptually harder than using Java, except for the occasional malloc/free
@Bob that's what global variables are for! :D (I'm not kidding; for a project of this scale, global variables in your primary/only translation unit are fine)
remember, I've done a non-trivial bit of coding with GLib, so I'm sort of bias. I don't find it convenient by any stretch of the imagination (the canonical truly convenient library is pretty much only .NET / C#, as far as I'm concerned) but I understand and can use it
then again, Vala is a nice wrapper around GLib/GObject that makes it almost as easy as actually using .NET itself o_O
late last year, I was lauded for developing a fairly high-impact utility to do some automated verification of some stuff (mumbles about details...) for my employer, and they were very happy, because it "found" an error with a potential financial impact in the 7 figures (USD)
I developed it in C# in 48 hours. I needed to be so fucking sure of my correctness that I actually wrote unit tests o_O
the thing that ended up really making my program sink or swim is that, in about hour 15 of coding, I realized I had some absolutely horrible code that was severely lacking in abstractions, so I sat back in my chair, scrolled through code for about half an hour until I wrapped my head around the needed abstractions, then wrote some pretty awesome data structures and wrapper functions and cleaned it up enormously
later on, they needed changes in my program at about hour 42 that would have demanded a severe re-write had I not done that refactoring
but since I had, I just changed some constants and was like "WHEEEEEEEEEEEEE DONE :D"
I started out with a YAGNI approach, but ended up making a fairly involved OO design that accounted for some potential future additions; i.e., "YGNI"
I wonder if a future release of Java will optimize away the boxing somehow, or maybe even allow primitives to be keys or values in collections? they would have to break backwards compat though, so... unlikely
the core problem is that when they first introduced javax.util.Collection (the interface), it assumes that everything in the Collection is an Object
similarly for the Map interface
they could introduce a "nutil" (like nio = new I/O, nutil = new utils), but it'd still be ugly and untidy
for one thing, generics did change the bytecode and runtime behavior in .NET, whereas generics in Java are a purely compile-time phenomenon, with no runtime effects
if java had done that, they could have easily supported Map<int, int> or so, but they chose to allow existing code that isn't aware of generics to continue to run fine (backwards and forwards compat) with code that is aware of generics
on the whole, Java is extremely tightly specified and against breaking backwards compat
Thread.stop() was never a good idea and never implemented quite right to begin with, and it's deprecated; there are a few bugbears like that in Java -- but hey, if you have code from JDK 1.1 that uses Thread.stop(), it'll probably at least kind of work, one would hope, on Oracle's Java implementation... though perhaps not on other JVM impls
LOL @Bob
a Java Thread can catch the ThreadDeath exception and keep on going :D
ThreadAbortException cannot be caught "completely"; it will automatically be rethrown at the end of the catch block (see the linked MSDN docs page) unless Thread.ResetAbort is called first.
So, the only sensible catch block would be:
catch (ThreadAbortException)
{

Heh.
I really don't like how you can't catch the StackOverflowException or OutOfMemoryException on C#...
"Single Entry, Single Exit" was written when most programming was done in assembly language, FORTRAN, or COBOL. It has been widely misinterpreted, because modern languages do not support the practices Dijkstra was warning against.
"Single Entry" meant "do not create alternate entry points for f...

@SEFolks is the network ok? :/
@alexus I'm afraid your question won't be getting reopened any time soon. It's asking for a software recommendation, which is off-topic for Super User.
Why does the following code produce a == 3?
var x = "abc";
var y = 3;
var z = "xyz";
var a = x && y || z;

I would have expected this to result in a == true.
Why is the logical operator evaluating "abc" as true but doesn't evaluate 3 as true. Instead i...
@alexus there might be a solution to your predickiment. You have software that prints to PDF, with the fatal flaw of it being relativly useless to doing anything :-) You could therin make a question with a problem. which will be a duplicate of the previous time somone had a PDF printer that would only print the first page. Heck frames gets to be a issue also. Some of these thing might be solved in the primo $$$ software for doing the same thing.
@alexus Or you could roll over to Software recommendations site, and ask there where they Desire that you have a few specifics in the recommendation. Knowing what you know now, you could go there and create a question, Insureing that you specify the full needs. Covering all the bases Which could already be a duplicate. (meaning to search there first)
@Boris_yo Please don't ask to ask; if you simply ask your actual question, we will help you if we know the answer or can help you find it. This is much faster and simpler than asking if it's OK to ask. As a rule, it is always OK to ask in this channel. Please go ahead.
@Boris_yo Keep in mind that starting with doesn't implies the negative (probably a better way to phrase that...) - you're more asking for confirmation of a "no". does this sound stupid is better for an actual question.
Doesn't this bird have wings? ==> in my head I'm really expecting you to say "yes, this bird does have wings" Don't birds have wings? ==> same thing, except plural format Do birds have wings? ==> I'm honestly asking, and I don't really expect a "yes" or "no" because I'm uncertain
We will be performing a read-only load test of our Oregon data center at 2 PM EST today. The Q&A sites will be in read-only mode for the duration of the test; when DNS redirects traffic to Oregon users will start seeing the read-only version of the sites hosted there. We expect to test load for about 15 to 20 minutes then direct traffic back to the active data center in New York. If you s…
as a refresher: BeagleBone runs an ssh command connecting it to the server. when a user logs into the server I first check the port to see if there is a connection there and if not display an error page. if there is a connection I pass them along to their dashboard.
now, SOMETIMES when the device boots and sends the ssh command the server doesn't listen on that port
like it ignored the SSH command.
it will work 10/10 for me, then an hour later 5/10
frustrating as hell.
:face-palm: okay, now its showing me in those 5 times the ssh command wasn't successfully run :/
@rlemon that doesn't mean necessarily that it wasn't successfully run; it could've started successfully, but died somewhere along the way, maybe even after it successfully connected at first
for instance, the connection could've dropped out
you need some kind of a log file on the clients that logs when the ssh process starts, including any verbose output from the ssh command, and then logs any process termination including the exit code
There is no Screen, so Windows Detects that there is no screen.
all you have to do is connect a monitor to it, you don't have to use it, just connect it.
I am looking for a way to do this without needed to install a monitor. Either via a fake (sfotware installable) monitor, very small (less than thumbdrive sized) monitor with high resolutions (e.g. 3840x1200. No actual output needed) or via a trick like RDP'ing from a host to itself and connecting teamviewer to that RDP session.
RDP from outside the laptop is blocked by the firewall. Corporate rules.
@Hennes so you need a edid dongle forum.arcadecontrols.com/index.php?topic=96780.0 this guy makes VGA ones (scroll to picture) Notice he said that stuff changed , being the maker trying to get the stuff to work. It is also odd because not long ago people were purposfully Pulling the EDID pin out of VGA, to purposfully configure without it (which would provide no data back)
So it would seem, that it is possible to configure completly without a screen or a dongle, although i have never done so.
As long as you write a proper post with enough information to be useful to everybody (not just us on the channel) and nobody comes along and posts a better answer I am happy to have played with a bounty. (First time I ever tried those)
@Hennes they are fun. check out the answer and let me know what you think. I am used to writing Code Review Answers so my answers may be a little rough around the edges
the main purpose for a bounty is to get more attention to a question, at least that is what I have used them for
The laptop I am currently using it on is a work laptop with an attached screen (low res display 1400x1050)
I usually leave the lid closed and connect a displayport to HDMI 'cable' to it and a IIyama 2607 (1920x1200) display
And then switch the display to DVI input which is connected to my main work desktop
That way I have one mouse, one keyboard, and no need for a third monitor
I can attach a third monitor. And maybe set it to an out of sync resolution.
But it annoys me that I would need a monitor at all. I just want to render (and the laptop has the hardware for that). I do not care about the output part.
Setting it to 2x 1920x1200 would be ideal because then I could switch between the laptop (full screen on both LCDs) and the normal desktop
Just a windows explorer with normal programs. (1x firefox with the EPAL webpage I am coding on, 1x PRFcat with the model I am copying to EPAL, 1x Siebel suite with more rules)
@Hennes that sounds like something I should look into. I have 2 laptops at home (1 Ubuntu and 1 Windows 7) and then I have a desktop (windows 8.1 pro) with dual monitors
Basically I open the model in PRFcat, display all the rules on a section and then code an equivalent of that in EPAL
Fun work. Partially done by mindlessly copying stuff. But also a lot of puzzling (why did they do it that way. Which options should I disable or enable).
E.g. Make an eartquicke kit mandatory for Japan
Force adding a Polish manual for poland (and an English one)
Ask people if they have a smart power supply or if they smoked somethign when a device accepts both (simultanious) 50Hz, 60Hz, 220v and 110v
Yes certannly if they are just communicating to software, it shoudl be possible to do it just with software. or some "force" switch in the drivers own software, registry hack or something.
Which was the answer I expect to get from the Super User post
As for hackish solutions. I can get a free passive DP to HDMI convertor at work (I already got a dozen on my name since kicked out all the VGA cables from my coworkers computers) and then use the 49 pound DVI dongle which Oliver posted.
@Hennes It could be some of the previous work done on hacking in new resolutions, and getting monitors that stay "blank" to work. Say 20 hours searching i might find it :-)
Because some crasy nutjob out there (genius that they are) has already spent days and days messing with that stuff, Where Are You Now?
