  • Cloning git repository from svn repository, results in file-less, remote-branch-less git repo.

    - by Tchalvak
    Working SVN repo I'm starting a git repo to interact with a svn repo. The svn repository is set and working fine, with a single commit of a basic README file in it. Checking it out works fine: tchalvak:~/test/svn-test$ svn checkout --username=myUsernameHere http://www.url.to/project/here/charityweb/ A charityweb/README Checked out revision 1. Failed git-svn clone of svn repo When I try to clone the repository in git, the first step shows no errors... tchalvak:~/test$ git svn clone -s --username=myUserNameHere http://www.url.to/project/here/charityweb/ Initialized empty Git repository in /home/tchalvak/test/charityweb/.git/ Authentication realm: <http://www.url.to/project/here:80> Charity Web Password for 'myUserNameHere': ...but results in a useless folder: tchalvak:~/test$ ls charityweb tchalvak:~/test$ cd charityweb/ tchalvak:~/test/charityweb$ ls tchalvak:~/test/charityweb$ ls -al total 12 drwxr-xr-x 3 tchalvak tchalvak 4096 2010-04-02 13:46 . drwxr-xr-x 4 tchalvak tchalvak 4096 2010-04-02 13:46 .. drwxr-xr-x 8 tchalvak tchalvak 4096 2010-04-02 13:47 .git tchalvak:~/test/charityweb$ git branch -av tchalvak:~/test/charityweb$ git status # On branch master # # Initial commit # nothing to commit (create/copy files and use "git add" to track) tchalvak:~/test/charityweb$ git fetch fatal: Where do you want to fetch from today? tchalvak:~/test/charityweb$ git rebase origin/master fatal: bad revision 'HEAD' fatal: Needed a single revision invalid upstream origin/master tchalvak:~/test/charityweb$ git log fatal: bad default revision 'HEAD' How do I get something I can commit back to? I expect I'm doing something wrong in this process, but what?

  • MUD source code

    - by Tchalvak
    I haven't been able to find a lot of the old, open source mud source codes. I find the way they did things very applicable to text-based/browser based games, and I'd love to be able to skim through parts of 'em for inspiration. For instance, we have this huge list of muds and the relationships between them, but little by way of access to source code. http://en.wikipedia.org/wiki/MUD_trees Often (I'm looking at you, dikumud, http://www.dikumud.com/links.aspx ) the sites of the mud itself doesn't even have a working link to the source. https://github.com/alexmchale/merc-mud has a copy of merc that I found, which certainly contains other works within it's history, but the pickings seems sparse. Does anyone have better resources for gaining access to MUD source code than these?

  • php image upload library

    - by Tchalvak
    I'm looking to NOT reinvent the wheel with an image upload system in php. Is there a good standalone library that allows for: Creating the system for uploading, renaming, and perhaps resizing images. Creating the front-end, html and/or javascript for the form upload parts of image upload. I've found a lot of image gallery systems, but no promising standalone system & ui libraries, ready for insertion into custom php.

  • Examples of interesting implementations of character stats?

    - by Tchalvak
    I've got this BBG going ( http://ninjawars.net ), and the character stats currently are simplistic. I'm looking to add a few stats to the current 1/2 (strength and maximum hitpoints, essentially). I've come up with: (strength (unchanged), speed, stamina, and some others that are somewhat interesting wildcard stats). However, I'm not satisfied with how boring the effects of some of these stats are, because they're very linear. Better stat, better effects of the stat, but the stats don't interact with each-other, there's no Rock-Paper-Scissors interaction, having more is always better all the time. So what I'd really like is to see examples of interesting character stats or effects of stats? Examples that I can think of off hand: Call of Cthulu's Insanity stat (things get really weird/chaotic if you start losing sanity) White Wolf stats, to a certain extent (the stats themselves have some basic effects, and all skills effectiveness base themselves off of stats as well) What are some other ways people have used stats to check out?

  • How do I determine problems with bootup based on this bootchart?

    - by Tchalvak
    So I've been having issues with lots of hard-drive usage during bootup and long bootup lately, and I installed bootchart to get these two bootcharts, but damn are there a lot of unfamiliar system stuff on there, it's hard to tell what is a warning sign, and what is simply normal during boot. Here is a bootchart with the advantage of a previously packed/?cached? boot: http://imgur.com/ScTAU Here is the same bootchart without the advantage of a packed boot: http://imgur.com/9jocF Can anyone make suggestions on what this is telling me needs fixing?

  • Crafting an effective php/web programmer job post template [closed]

    - by Tchalvak
    I am looking to create a job post to get a satisfactory assistant programmer / templater. Specifically, a php & web programmer. I am, however, afraid of forgetting important things. So, are there resources you can suggest for templates for things to ask and things to tell in a job post for a programmer? Surprisingly, I wasn't able to find similar questions on this site, so there may be duplicate questions out there that I could use but just didn't find. Right now I know that my -requirements- are so generic that they're going to get me in trouble with a spam of applications. e.g. the candidate must know php, must be able to seperate php from html. So I'm looking for criteria that are must-haves, must-mentions, or a general template to try to avoid a "lemon". I also started a gist to work on a job post, comments/edits would be excellent: https://gist.github.com/2906808

  • How can I refresh/reinstall/clear/set-to-default my bootup process?

    - by Tchalvak
    I'm currently having a problem with my bootup process that is growing progressively worse as time goes on: While booting, it does a few minutes of hard-drive reading. During that, instead of showing a boot splash screen, it shows various dashes and dots, as if the video card isn't recognizing. The splash screen actually has colors similar to the splash screen (purple), it simply is garbled. It then does a few minutes of hard-drive reads, and if I leave it long enough, sometimes it boots into the desktop (and auto-logs-in). Sometimes, unfortunately, it just hangs on that garbled screen and reads from the hard-drive forever. Notably, I've also stopped being able to access grub during bootup (perhaps it is just not displayed correctly by the video, hard to tell). This is a symptom that has grown over the course of various ubuntu upgrades, at least I suspect that the upgrade process is leaving behind cruft. So, is there a safe way for me to "refresh" the boot system so that it is clean, new, fast, and reliable? For example, to test out a cleanly configured boot, make sure that it works (try before I buy), and then apply it to the system to eliminate as much of this problem as possible? Edit: Here is the requested bootchart: http://imgur.com/9jocF

  • What steps to take in resolving/fixing/optimizing a long boot, with possible looping errors as the culprit

    - by Tchalvak
    So my boot time has been slowing and slowing as time has gone on... I am running a number of services (e.g. apache/mysql, postgresql), but it has seen a drastic slowing lately, while I've only been applying updates as normal. I happened to check out my /var/log/boot.log and it is spammed with many lines of this: init: upstart-udev-bridge main process (2738) terminated with status 1 init: upstart-udev-bridge main process ended, respawning I wasn't able to find any solutions to that issue in google, or much talk of it at all, and I'm not really certain that error is the problem, but it is the only lead that I have. What steps should I go through to diagnose boot problems/a slow bootup?

  • What steps/tools/apps are necessary to make local php development on a tablet viable?

    - by Tchalvak
    I do my php web development locally, as in, creating a local instance of a site and then coding it and then pushing code to servers via git/github. I'm considering getting an android tablet or ipad and a wireless keyboard for very mobile development, but I in no way want to go back to the bad old days of using ftp and syncing up code changes on a development server directly, that would be too much of a trade-off to interest me. Is there enough support for the stack to develop php websites locally on a tablet? Anyone had experience trying this sort of thing?

  • Name attribute is obsolete, what is the correct behavior when dealing with anchors?

    - by Tchalvak
    Putting some code through the html5 validator, I get this: Warning: The name attribute on the a element is obsolete. Consider putting an id attribute on the nearest container instead. I find that unclear. Is the "nearest container" for an anchor link the a itself, so that the correct code would be <a id='blah'> instead of <a name='blah'>? Or are empty placeholder <a> tags as a whole deprecated, and anchors can simply point to any element with an id instead?

  • Disadvantages of a fake phpMyAdmin honeypot that causes ip blacklisting and robots.txt disallow/exclusion of the honeypot?

    - by Tchalvak
    I'm trying to figure out whether I should set up a honeypot system with a fake phpMyAdmin (site gets hits all the time with people spidering for insecurities with that app). My thought was to create a honeypot php script that would mimic a phpMyAdmin login, and then blacklist ips that hit that url (and aren't already whitelisted). I would then add the appropriate urls to the robots.txt so that spiders that actually respect my robots.txt wouldn't be caught by the blacklist. Are there disadvantages to this approach, do legit robots sometimes not respect robots.txt in certain circumstances, are there any problems with this that I should consider in advance?

  • I'm seeing a lot of a new format for title elements for major sites: a few tags, and only then the title of the site itself, is this now optimal SEO?

    - by Tchalvak
    I'm seeing a lot of sites go to a format similar to the one now in use by stackexchange sites (i.e. short topic - maybe a long topic - only finally the site's name). Is this optimal SEO? It seems kind weird both because I'm only begun to notice changes in this direction recently, and because it seems like it would make it harder to tell in search results which actual site you're visiting, even if the topic is one that matches. Still, sites like Facebook, StackOverflow, etc probably aren't wrong, so I'm wondering if I should try to make my sites use that format, going forwards...

  • How can I get access to password hashing in postgresql? Tried installing postgresql-contrib in ubun

    - by Tchalvak
    So I'm trying to just hash some passwords in postgresql, and the only hashing solution that I've found for postgresql is part of the pgcrytpo package ( http://www.postgresql.org/docs/8.3/static/pgcrypto.html ) that is supposed to be in postgresql-contrib ( http://www.postgresql.org/docs/8.3/static/contrib.html ). So I installed postgresql-contrib, (sudo apt-get install postgresql-contrib), restarted my server (as a simple way to restart postgresql). However, I still don't have access to any of the functions for hashing that are supposed to be in postgresql-contrib, e.g.: ninjawars=# select crypt('global salt' || 'new password' || 'user created date', gen_salt('sha256')); ERROR: function gen_salt(unknown) does not exist ninjawars=# select digest('test', 'sha256') from players limit 1; ERROR: function digest(unknown, unknown) does not exist ninjawars=# select hmac('test', 'sha256') from players limit 1; ERROR: function hmac(unknown, unknown) does not exist So how can I hash passwords in postgresql, on ubuntu?

  • Way to avoid ssh connection timeout & freezing of terminal tab

    - by Tchalvak
    When I connect via ssh terminal to certain servers, it timeouts and "freezes" the terminal (doesn't accept, doesn't disconnect, can't Ctrl-C to kill the ssh process or anything). This is in Ubuntu's Gnome-terminal, though it seems to be pausing the terminal input/output, and doesn't affect the operation of the Gnome-terminal software itself. so less a bug with gnome-terminal than an annoying inconsistency with ssh. So is there a way to prevent regain the terminal from ssh connections that have timed out?

  • What response should be made to a continued web-app crack attempt?

    - by Tchalvak
    I've issues with a continuous, concerted cracking attempt on a website (coded in php). The main problem is sql-injection attempts, running on a Debian server. A secondary effect of the problem is being spidered or repeatedly spammed with urls that, though a security hole has been closed, are still obviously related attempts to crack the site, and continue to add load to the site, and thus should be blocked. So what measures can I take to: A: Block known intruders/known attack machines (notably making themselves anonymous via botnet or relaying servers) to prevent their repeated, continuous, timed access from affecting the load of the site, and B: report & respond to the attack (I'm aware that the reporting to law enforcement is almost certainly futile, as may be reporting to the ip/machine where the attacks are originating, but other responses to take would be welcome).

  • sudoer scheme for another web developer that retains my future control of a virtual server?

    - by Tchalvak
    Background: Virtual Private Server I have a virtual private server that I'm looking to host multiple websites on, and provide access to another web developer. I don't care about putting too many constraints on him, though I wouldn't mind isolating the site that he'll be developing from other sites on the server that I will develop. The problem: retain control Mainly what I want is to make sure that I retain control over the server in the future. I want to reserve the ability to create/promote/demote and other administrative functions that don't deal with web software. If I make him an admin, he can sudo su - and become root and remove root control from me, for example. I need him not to be able to: take away other admin permissions change the root password have control over other security/administrative functions I would like him to still be able to: install software (through apt-get) restart apache access mysql configure mysql/apache reboot edit web development configuration type files in /etc/ Other Standard Setups would be happily considered I've never really set up a good sudoers file, so simple example setups would be very useful, even if they're only somewhat similar to the settings that I'm hoping for above. Edit: I have not yet finalized permissions, standard, useful sudo setups are certainly an option, the lists above are more what I'm hoping I can do, I don't know that that setup can be done.

  • Is there any reason to install software as root as opposed to sudo installing software as a sudoer?

    - by Tchalvak
    I'm setting up a new server running Ubuntu Server Edition, and I'm not certain what the difference would be between installing most of the basic software as root, vs installing the basic software as an admin user using sudo apt-get install . For one thing, I'm not sure whether after installing the software as root, I'll need sudo access when running the software as a user (e.g. if I install git as root). On the other hand, if I install software as a user, I could conceive of it not being available to other users that I create in the future. What's the best practice here?

  • Where is the best location to keep shared-developer website files in the linux hierarchy?

    - by Tchalvak
    I just started hosting files for a website on my server, and I'm not sure where is an appropriate place to keep them. At the moment, I have them in /var/www/name.of.virtualhost.site/www/. That's obviously not secure because anything below the final public /www/ folder is also available since the /var/www/ contents are already being served up. For example, /var/www/name.of.virtualhost.site/docs/site_policies.txt is accessible via something like defaultsite.com/name.of.virtualhost.site/docs/site_policies.txt. So where is a good place to store the files that make up a website? (when it's a site that only I'm developing, I can obviously just stick them in /home/my_username/sites/name.of.virtualhost.site/, but that doesn't work well when I want other developers to be working on the site's files as well) I'm running a LAMP stack, not that I expect it to matter.

  • How can I configure apache to cache the images that it is serving? Right now it is giving headers t

    Serving up images that don't seem to cache There's a LAPP (postgresql instead of mysql) running over on http://ninjawars.net. I just recently noticed that images don't seem to be caching with any kind of good frequency as I was reloading a page with a few images on it here: http://www.ninjawars.net/attack_player.php Here is an example image (they're probably all being served exactly the same): http://www.ninjawars.net/images/characters/fighter.png Checking the header, it seems that the caching is set to: Cache-Control:max-age=0 (the full header for this image-like-all-the-others is...

  • Optimizing wireless router speed and minimizing interference.

    - by Tchalvak
    I've been experiencing problems with my wireless connectivity lately, and want to make sure that it's not related to the abundance of other wireless routers here in my building. So, what I'm looking for is a method (probably via some application or another) to audit the wireless channels (and other factors that might be important that I don't even know of yet) that are floating through the aether around me. Ubuntu or other linux apps are preferred, but some kind of windows/mac solution is possible, since I do have other OSes around me that I could install & test on. Router: netgear WGT624 v3 Hearsay tells me that channels 1, 6, and 11 are "non-overlapping" (I expect they aren't used for non-wireless-router purposes or something, not sure how they couldn't overlap with other routers using other channels), so perhaps my best choices of channel are limited, so if channels aren't really a big concern, I'd be happy to get links to other optimizations that I should look into.

  • Where is the hostname in /etc/hostname on a debian server used?

    I have a webserver running a number of websites. When I ssh in, it gives me a tab name of [email protected], which is counterintuitive, making it seem like those tabs are on my localhost. I would like to change the hostname, but I want to be sure that it won't break anything else. So for what purposes does that hostname string get used, and how can I be sure that it won't affect any functioning systems?
