• I need a decent alternative to c++ [closed]

  - by wxiiir

  I've learned php and c++, i will list the things i liked and didn't liked on each of them, how i decided to learn them in the first place and why i feel the need to learn a decent alternative to c++, i'm not a professional programmer and only do projects for myself. PHP - Decided to learn because i wanted to build a dynamic website, that i did and turned out very good, i even coded a 'not so basic' search engine for it that would display the results 'google style' and really fast, pretty cool stuff. PROS - Pretty consistent syntax for all stuff (minor caveats), great functionality, a joy for me to code in it (it seems to 'know' what i want it to do and just does it) CONS - Painfully slow for number crunching (which takes me to c++ that i only learned because i wanted to do some number crunching and it had to be screaming fast) C++ - Learned because number crunching was so slow in php and manipulating large amounts of data was very difficult, i thought, it's popular programming language and all, and tests show that it's fast, the basic stuff resemble php so it shouldn't be hard to pick up PROS - It can be used to virtually anything, very very fast CONS - Although fun to code at the start, if i need to do something out of the ordinary, memory allocation routines, pointer stuff, stack sizes etc... will get me tired really quick, syntax is a bit inconsistent some times (more caveats) I guess that from what i wrote you guys will understand what i'm looking for, there are thousands of languages out there, it's likely that one of them will suit my needs, i've been seeing stuff today and a friend of mine that is a professional programmer tried OCaml and Fortran and said that both are fast for numerical stuff, i've been inclined to test Fortran, but i need some more input because i want to have some other good 'candidates' to choose from, for example the python syntax seemed great to me, but then i found out from some tests that it was a lot slower than c++ and i simply don't want to twiddle my thumbs all day.

• Update-manager fails silently on 14.04

  - by pabuisson

  I recently reinstalled a lubuntu from scratch, to upgrade to 14.04. Everything's working as expected, except for the update-manager that silently fails when trying to upgrade my system's packages. It does correctly list the packages to be upgraded, I can then click on the "Install now" button (or something like this, I'm running a French flavour of Ubuntu). When I click the button, it seems unresponsive for 5 to 10 seconds, then the upgrade dialog with the progress bar appears, displays "Loading package list", then very shortly something about "authentication" (not long enough so that I can read it).. and closes. The install is fresh and I have no idea where to look. I tried launching update-manager in a term but it doesn't display any error when it fails, only this message when the window first shows up : ** (update-manager:3642): WARNING **: Couldn't connect to accessibility bus: Failed to connect to socket /tmp/dbus-m0jkFlZ3yo: Connexion refusée. Any idea where this might come from ? I can upgrade the packages using the command line and sudo apt-get but this is not my computer, and I do not wish its owner to have to do this to upgrade the packages. Thanks for your help !

• Apache redirect alias to a different domain

  - by John Magnolia

  I previous had both Web and Mail on the same server and for each of my vhosts/domains, I could visit example.com/mail or foo.com/mail which would display the Roundcube Webmail across all vhosts. E.g Alias /mail "/usr/share/apache2/roundcub/" Although now I have moved the Mail server onto a completely different server and now have a SSL for the main domain. https://mail.example.com which is now the new location of Roundcube for all vhosts/domains. Question: is it possible to redirect all alias for "/mail" from the Web server to the new URL?

• Clearing the terminal before displaying MOTD

  - by user1417933

  When I connect to my SSH server, it prompts me for the user name and password. After I have authenticated, it will display my MOTD, then show user prompt, like this: Using username "root". Authenticating with public key "everssh" this is my motd root@debian:~# I want to edit some file so that the screen is cleared before the MOTD prints (so basically calling the clear command would do). I heard that the MOTD is displayed by using cat /etc/motd in a startup file, however after searching around I can't find where it is called from. Does anyone know how I can find it?

• Why does the Mobile Safari Browser on iOS not allow file uploads? [migrated]

  - by Kirinriki

  As already known, it's not possible for iOS users to select image files to upload from Safari on iPhone, because the browse button to display the "select file"- dialog is disabled. It works fine on Android, but not on iPhone... What is the particular reason for that issue? I heard that the browse button is disabled because there isn't a file browser on the iPhone. Someone other said that Safari just disabled root access. Is there any reliable source which explains the issue? (I need it for my thesis.)

• Algorithm to zoom a plotted function

  - by astinx

  I'm making a game in android and I need plot a function, my algorithm is this: @Override protected void onDraw(Canvas canvas) { float e = 0.5f; //from -x axis to +x evaluate f(x) for (float x = -z(canvas.getWidth()); x < z(canvas.getWidth()); x+=e) { float x1,y1; x1 = x; y1 = f(x); canvas.drawPoint((canvas.getWidth()/2)+x1, (canvas.getHeight()/2)-y1, paintWhite); } super.onDraw(canvas); } This is how it works. If my function is, for example f(x)=x^2, then z(x) is sqrt(x). I evaluate each point between -z(x) to z(x) and then I draw them. As you can see I use the half of the size of the screen to put the function in the middle of the screen. The problem isn't that the code isn't working, actually plots the function. But if the screen is of 320*480 then this function will be really tiny like in the image below. My question is: how can I change this algorithm to scale the function?. BTW what I'm really wanting to do is trace a route to later display an animated sprite, so actually scale this image doesnt gonna help me. I need change the algorithm in order to draw the same interval but in a larger space. Any tip helps, thanks! Current working result Desired result UPDATE: I will try explain more in detail what the problem is. Given this interval [-15...15] (-z(x) to z(x)) I need divide this points in a bigger interval [-320...320] (-x to x). For example, when you use some plotting software like this one. Although the div where is contain the function has 640 px of width, you dont see that the interval is from -320 to 320, you see that the interval is from -6 to 6. How can I achieve this?

• Share Only 1 folder using SMB

  - by SnippetSpace

  I want to share my "My Videos" folder using Windows's built in SMB. The problem is that when I decide to share my video folder and check it on another device, the path always is: networkname>username>my videos instead of just my videos I noticed that indeed sharing gets turned on from the user folder down to the video folder instead of just on the folder I selected. So now my question is why this is happening; And how cold I just display my "my Videos" folder on my remote device and not the entire path? BTW device in question is a hacked Apple TV. thank you for your help! Christopher

• What is the easiest way to apply database functionality into my daily life?

  - by Daddy Warbox

  let me try to explain it by listing some of the things I want to do: Submit random thoughts, notes, facts, and to-do tasks of any sort and at any time. Tag each of these submissions freely. Manage these tags centrally. Associate meta-data with submissions and tags. Search, filter, and sort submissions. I want lots of power here. Display views of submissions (including within searches) in a hierarchy. Create said hierarchies easily out by ordering relevant tags. I'm thinking towards some kind of desktop program that allows me to quickly do all of these things. A web service could also work, too, but it will need offline capabilities. I don't want to have to pay for this, if that's possible. Also, as I know regex and SQL, I wouldn't mind solutions involving the use of either.

• Windows 7 shared folder status info not showing in details pane

  - by Mike

  Just upgraded my system to Windows 7 a few hours ago and noticed that there was no shared overlay icon on my shared folders anymore and after doing some reading I discovered that the icon was removed in Windows 7, stupid decision but w/eve. Anyway I have been reading that if a folder is shared then you can still see the shared status of a folder in the details pane in explorer whenever you select the folder, but this information is not available to me for some reason and I am not sure why. When I click on a shared folder in explorer the only information I see in the details pane is the folders name and the modified date/time info which is the same information I see for a folder that is not shared so my question is how do I get this information to display in the details pane like it's supposed to be.

• How to get the finer resolution for asus eee pc 1000hd after installing windows7?

  - by vij

  Hi i have installed windows 7 on my 2 year old ASUS EEE PC 1000HD. The default Operating system it came with was windows xp. Now the system is working fine but there are some display problems which i am going to state now: Firstly, during booting windows 7 logo is missing. There are no options for resolution changes. The only option possible is 800x600. The boot time is quite long when compared to xp. The graphics driver used in this system is STANDARD VGA GRAPHICS ADAPTER. The processor is intel celeron with 1GB RAM. I think with these requirements it is possible to get windows 7 with finer resolution. But why these problems are occurring?I even tried to install graphics driver provided by intel for this system. But i ve got the error message "this system doesn't meet the necessary requirements". So how to overcome this problem??

• What kind of time lapse image stitching software is out there?

  - by AaronLS

  I took a bunch of digital images(jpg format) of a sunrise that I want to make into a time lapse movie. The only recommendation I've seen was some iStopMotion for Mac, but I am running Windows. I would prefer the software to take into account the metadata in the image that indicates what time the image was taken when determining how long to display each frame, as they won't be accurately consistent in their temporal spacing. Onion skinning would be a cool feature to. Please, one software suggestion per answer to allow the voting system to do it's job. Thanks in advance.

• How can I restore the stored password in firefox 15.0.1 when deleted by error?

  - by Bob Legringe

  I, by error, deleted my stored passwords, using the "Wise disc cleaner 7" program. As I saw on another thread, the passwords are stored in 2 files signons.sqlite and the encryption key file key3.db When opening the file signons.sqlite with the text editor, I can see that the web adresses of the sites belonging to the passwords are still there. They have not been deleted by the "Wise disc cleaner 7" program, and adding a stored password on Firefox just modifies the file. However, Firefox will not display my old stored passwords and neither their respective sites. Is there any way to "undelete" the passwords?

• When does a cached website refresh?

  - by user142485

  If i go to example.com [placeholder for different website] it creates the numerous cache entries in the browser for different items on the page and two entries for example.com. One of which expires in 1.5hrs and the other has 'No expiration time.' What I am wondering is: when does the browser display the cached page and when does it get the newest version from the server (when re-visiting the site)? What do the two different expiration times for the top level domain mean? A web page I went to was temporarily redirecting to a different page. After it was back up, I was still getting redirected to the temp page even though the correct page was up. Would this have eventually resolved itself based on expiration times or does the cache need to be cleared?

• How do I get dynamic subdomains on domain aliases in Plesk? [closed]

  - by mitchdesign

  I am running a site that is available via many domains. So all domains depend on the same code, but depending on the requested domain, the correct information is shown to the user. In Plesk, I have one domain set up and it has domain aliases for all the others. This works ok. Now, I'd like to be able to use subdomains on those aliased domains. Like the domains, the subdomains will be used as input for the system to display the correct information. So, they are not a fixed set. What I have done: - In DNS I have added *.example.com CNAME example.com to the main domain. This is automatically copied by Plesk to all the aliases. So DNS-wise, I think it's ok. - I have added a vhost.conf file to the main domain, containing ServerAlias *.maindomain.tld. This works for the main domain. But still, not for the aliased domains. And there is no place to put vhost.conf files for the aliased domains.. How do I tell the server to respond to those domain's subdomains as well?

• Show image in cell based on cell value

  - by JoeM

  I am creating a weekly income comparison table. I want to compare A5 and A10 cells and display appropriate image in B7 cell. The image will be either UP or DOWN arrow (which reflects increase or decrease). I've created a formula which puts text up or down in the cell, but I don't know how to replace it with the up/down image. =IF(D77>D69, "up", IF(D77<D69, "down")) How can I do it? I know it's possible. Note: I am using Google Docs Excel, so please let me know if this cannot be done in it, but I have to use the real Excel installed on my laptop.

• Filtering downloading a file

  - by Ozgun Sunal

  people. i know there are several types of firewalls operating at different layers of OSI. ACLs(layer 3 firewalls filter based on port numbers and IP addresses), SPI(which examines the patterns of data at layer 3 and realise that data content is malicious or not) and application layer firewalls which is capable of understanding the data at that level. Considering this, i'll give an example and learn what i need to do. Lets say, we have a computer has access to the Internet. i want to download a file or display a web page from a website but block access to the another website/s or downloading. To do this, i cant block access to the web browser on the 3rd party firewall bcos that will shut down all access. ACLs wont already do it. So, which kind of firewall will make it possible to filter specific traffic and how?

• Regular expression in mySQL [migrated]

  - by Rayne

  I have a mysql table that has 2 columns - Column 1 contains a string value, and Column 2 contains the number of times that string value occurred. I'm trying to find the string abc.X.def, where the beginning of the string is "abc.", followed by one or more characters, then the string ".def". There could be more characters following ".def". How can I find such strings, then add the occurrence of such strings and display the results? For example, if I have abc.111.def23 1 abc.111.def 2 abc.22.def444 1 abc.111.def 1 Then I will get abc.111.def23 1 abc.111.def 3 abc.22.def444 1 Thank you.

• Measuring custom statistics with sar

  - by Will Glass

  I have a server application which I think is leaking file handles. I want to track the usage of file descriptors over time on my Linux (ubuntu) server. I've figured out that I can track the number of file descriptors in use by a process with lsof -p `pgrep the-process-name` | wc -l Since I'm already using sysstat and sar to track various metrics, I thought it'd be nice to display with sar. I want to measure this every 10 minutes. Is it possible to add a custom metric to sar? Then I can easily report it out. If not, I'll write a simple cron job to collect this data and store it separately in a log file.

• Nvidia drivers with GeForce 680M problem [closed]

  Possible Duplicate: There's an issue with an Alpha/Beta Release of Ubuntu, what should I do? I have a new Alienware M17x which I have installed 64-bit Ubuntu 12.10 (dual boot). I have tried various ways to install the Nvidia drivers for the GeForce GTX 680M (which they claim they are compatible with): from Ubuntu Software Centre (though Additional Drivers fails to detect the card.) using sudo apt-get install nvidia-current downloading the drivers from nvidia and manually installing them (ctrl + alt + F6, sudo service lightdm stop, sudo ./NVIDIA*, sudo reboot) (each with a clean install of Ubuntu) but in all cases, when I reboot after installing nvidia-setings claims that I am not using the driver and should sudo nvidia-xconfig from the terminal, which I do but this has no effect and I am stuck in crappy resolution until I rm /etc/X11/xorg.conf and reboot.

• Drupal + GMap macro, map markers not displayed

  - by mingos

  Hi. I've run into a strange problem in the GMap module for Drupal. When I display a map inside a node using a GMap macro, everything is displayed correctly (according to what I specify in the macro or leave at default), save for map markers. I'm trying to specify a map marker, but it refuses to be displayed. My macro is the following: [gmap zoom=17 |center=53.77420697757659,20.474138259887695 |markers=big blue::53.77420697757659,20.474138259887695] I was unable to find any help on Drupal forums, both the official one and one local to my country. For completeness' sake, I do not wish to use a GMap view, just add a macro in a regular node. Hope you can help me find a solution. Thanks in advance for your replies...

• Missing Font on Page in Firefox, Worked before and Still Works Now in Other Browsers

  - by Keavon

  On any new Steam profile, there are many parts of the page (such as the username) that is supposed to be following this font hierarchy: 'Motiva Sans Thin',Arial,Helvetica,Verdana,sans-serif However, Motiva Sans Thin is not showing in Firefox anymore. It used to several days earlier, but now it reverts to Arial. Chrome, the Steam client, and other browsers still display Motiva Sans Thin, which leads me to believe it's still in my system's fonts, or still being provided as a web font. I have tried creating a new Firefox profile to no avail. It's been doing this for about two weeks now. Why is Firefox no longer displaying the font when it used to, and other browsers still do? How can I fix this? Thanks.

• Can't install GTX 680 drivers on 12.04

  - by user68945

  I recently installed Ubuntu 12.04 on my desktop. I have three monitors, and after installing, ubuntu only detected one at 1080p. I downloaded the driver from the nvidia website, but when I stop lightdm and try to run the driver, it gives me an error message: ERROR: Unable to find the kernel source tree for the currently running kernel. Please make sure you have installed the kernel source files for your kernel and that they are properly configured; on Red Hat Linux systems, for example, be sure you have the 'kernel-source' or 'kernel-devel' RPM installed. If you know the correct kernel source files are installed, you may specify the kernel source path with the '--kernel-source-path' command line option. I tried instead to install the driver via the terminal, with the X ppa. The installation seemed to work, but when I rebooted, my display was at 640x480 resolution, with no other options for resolution. The NVIDIA X Server settings program is there now, but when I run it, it simply tells me that I don't seem to be using their driver, and that I should run nvidia-xconfig as root. Doing so doesn't help, I simply get the same issue again. I checked the file at /etc/X11/xorg.conf, and it's an NVIDIA file (has nvidia in the header). Does anyone know something else I can try? EDIT: Forgot to mention, I tried installing drivers via the "Additional Drivers" GUI utility, there were two options, one of them marked "(post-release updates)". I tried both of them, in both cases it tried to download and install for a while, then said that there was an error, and that a description could be found at /var/log/jockey.log. Both logs were over 700 lines
