  • Setup CRON weekly backup

    - by sadmicrowave
    I want to make a backup of my /var/lib/mysql and /var/www folders and save them as tar.gz files to my mounted network file server (uslons001). Here is my bash file located in: /etc/cron.weekly/mysqlbackup.sh #!/bin/bash mkdir ~/uslons001/`date +%d%m%y` tar -czf ~/uslons001/`date +%d%m%y`/mysql.tar.gz /var/lib/mysql tar -czf ~/uslons001/`date +%d%m%y`/www.tar.gz /var/www tar -czf ~/uslons001/`date +%d%m%y`.tar.gz ~/uslons001/`date +%d%m%y` echo Backup Completed `date` >> ~/backuplog Which works PERFECTLY fine when I execute it in a cmd shell but when I setup the cron job it never runs, so I'm not setting the cron job up properly. My cron job looks like this. 30 7 * * fri /etc/cron.weekly/mysqlbackup.sh Which should execute at 7:30AM every Friday... What am I doing wrong? UPDATE1 - change the cron job line to the following: 44 8 * * 5 /etc/cron.weekly/mysqlbackup.sh with still no luck...is there a cron error log file that I can read to help pin point where the problem is?

  • Should you charge clients hours spent on the wrong track?

    - by Lea Verou
    I took up a small CSS challenge to solve for a client and I'm going to be paid on a hourly rate. I eventually solved it, it took 4 hours but I spent roughly 30% of the time in the wrong track, trying a CSS3 solution that only worked in recent browsers and finally discovering that no fallback is possible via JS (like I originally thought). Should I charge the client that 30%? More details: I didn't provide an estimate, I liked the challenge per se, so I started working on it before giving an estimate (but I have worked with him before, so I know he's not one of those people that have unrealistic expectations). At the very worst I will have spent 4 unpaid hours on an intriguing CSS challenge. And I will give the fairest possible estimate for both of us, since I will have already done the work. :)

  • How to effectively gather info about how players play my HTML5 game?

    - by Bane
    I'm finishing another HTML5 game, and this time I'd like to do some spying business on the players... Mostly just basic stuff: when they are playing, for how long, what upgrades they are buying the most and so on. Now, my first idea was just to collect this information during the gameplay, and then have a Javascript function fire when they close the tab/browser, and said function would send it to my server via Socket.io. This, of course, wouldn't work, because anyone who takes a look at the code would realize it and could start sending a tonne of false info which would mess up my statistics. Questions: Is there a way to effectively do this? If yes, what kind of info should I be looking for, aside from stuff I already mentioned?

  • Store HighRes photos in Database or as File?

    - by David
    I run a site which has a couple of million photos and gets over 1000 photos uploaded each day. Up to now, we haven't kept the original file that was uploaded to conserve on space. However, we are getting to a point that we are starting to see a need to have high-res original versions. I was wondering if its better to store these in the filesystem as an actual file or if its better to store them in a database (ie: mysql). The highres images would be rarely referenced but may be used when someone decides to download it or we decide to use it for rare processes like making a new set of thumbnails sizes/etc.

  • What Is StreamInsight? A Primer for Non-Programmers

    - by Roman Schindlauer
    Are you trying to figure out whether StreamInsight might be something you could use, but you’re having trouble sifting through all the programming jargon that’s used to describe it? StreamInsight is, ultimately, a set of programming tools, and at some point it takes a programmer to implement a StreamInsight solution. But it really should be possible to get a handle on what StreamInsight is all about even if you’re not a programmer yourself. A new article published in the TechNet Wiki may be able to help: StreamInsight for Non-Programmers. It gives an overview of the technology, but it leaves out the C# references and relates StreamInsight to more familiar SQL databases and queries. Check it out. When you’re done there and are ready to dig a little deeper, take a look at Get Started with StreamInsight 2.1. That article should help you navigate through the StreamInsight official documentation and other resources. And, as always, you can post questions or comments here or on the TechNet Wiki. Regards, The StreamInsight Team

  • How to estimate tasks in scrum?

    - by Arian
    Let's say we have a backlog of User Stories, each with an estimated number of Story Points, and now we're doing the Sprint Planning. Now, the Stories should be broken down into tasks and many Scrum resources suggest that each task should be estimated in person-hours. Since all questions have been discussed by the team at this point, estimating a task should not take longer than a minute. However, since a task should not be longer than a day, assuming a three week sprint with 8 developers means 120 tasks, and taking two hours only for estimations seems to be a bit much to me. I know that experienced teams can skip or short-cut task estimations, but let's say we're not at that stage yet. In your experience, how many tasks are there in a sprint* and how long should it take to estimate all of them? (Estimating only half of them doesn't make much sense, does it?) (*) I know that depends on sprint length and team size, so let's assume 8 developers and three weeks.

  • Marek's JAX-RS 2.0 content from Devoxx 2011

    - by alexismp
    Marek Potociar, one of the two co-spec leads for the upcoming JAX-RS 2.0 had a very well-attended session at Devoxx and wrote a blog post about it detailing his conference experience (1st time at Devoxx) and running through the new features of the specification. A link to slides is also included in his post. The work by the expert group seems very solid at this point as you can read for yourself in details in the recently published early draft document. You can follow the remaining work between now and the middle of new year on the specification project pages on java.net.

  • Assign subdomains to separate ports on web server

    - by Michael Frank
    I have set up an Abyss web server as a little experiment, and I want to know if it is possible to assign subdomains to different ports on the machine the web server is running on. I have a couple webUIs that I'd like to assign subdomains: 192.168.1.1:8000 becomes example.com/webui1/ 192.168.1.1:8001 becomes example.com/webui2/ The webUIs are available by accessing their ports via example.com:8000. I have tried using a reverse proxy, but it seems that this is only usable on one internal IP at a time. What other options do I have? Answer is good, but my current set up doesn't meet the requirements. Abyss Web Server X2 is required to use Virtual Hosts with Abyss.

  • How to build a team of people not working together?

    - by Bernd
    I am in charge of a group of about 30 software development experts and architects. While these people are co-located in the companies organization chart, they do not really feel as a team. This is due to their work enviroment: 1) The people are spread over eight locations, with a max. distance of about 1000km (this is Europe). 2) The people don't work as team but instead get called as single people (and sometimes small groups into projects for as long as the projects run. 3) Travelling is somewhat limited as this requires business reasons. Lot is done via phone. Do you have ideas or suggestions on how I could make these people feeling part of a joint organization where they support others and get supported by others. So that they get to know their peers, build a network, informally exchange information? So that they generally get the feeling of having common ground and derive motivation and job satisfaction?

  • Intel obligé de rappeler ses puces Sandy Bridge, à cause d'un problème de port SATA

    Intel obligé de rappeler ses puces Sandy Bridge à cause d'un problème de port SATA, il pourrait lui en coûter 1 milliard de dollars Mise à jour du 01.02.2011 par Katleen Parfois, une petite erreur peut chambouler de grandes choses.

  • What's the location of a personal 'gtkrc' file in Ubuntu 12.04?

    - by Kevin Perez
    Good day everyone! I am currently writting a software that makes easy to change default cursor theme with a few clicks. At this point it works well, but applications like Firefox or Lazarus IDE remain with the DMZ-White cursor, everything else is ok. I noticed that when I change the default cursor using my software, and later change the 'personalized' cursor theme using Ubuntu Tweak, it does the job, and the new theme is now applied everywhere. So, what file is need to modify in order to change 'personal' cursor theme? If my software can do this, that would be great! I found that 'gtkrc' is a file where settings of GTK+ are stored. I searched in my home folder but I can't find yet. Can you help me with this, noble people of Ubuntu? :)

  • APIs that deal with logins

    - by Brandon Still
    I have been asked to make a mobile app for a friends website. The website is a Multi level marketing site that sells products and franchises. A client logs in in to the website and can view his or her dashboard ( user can view team members, business volume, commissions, invoices, etc.) The app is supposed to bring the dashboard to user's mobile devices (w/ some added features). The company does not have any APIs that deal with interaction or authentication, and I am new to the whole secure login side of app development. My questions is this, how do I let the users gain access to their information via my app from the secure website when there is no API?

  • Ubuntu One API Java - how to use REST and AccessToken?

    - by Michael
    I am writing a java app in eclipse that backups data to several consumer-cloud-services encrypted and redundant. So far, I successfully implemented the authentication process, as it is described in the documentation. At this point, I do not know how to proceed. The next step would be implementing the auth with the stored AccessToken and afterwars implementing upload/download/listing functionality through the REST API. I think I have to store the String oauth.getSerialized(). How do I authenticate with this String afterwards? This does not work e.g.: AuthenticateResponse oauth = api.authenticate(serialized); api.setAuthorizer(new OAuthAuthorizer(oauth)); Can someone tell me please, how I can use the REST API with java? There is no explanation or link in the developers area as far as I saw. And btw, I wasted at least one hour trying to fix errors, because some needed libraries are listet after the example code. :/

  • RPG level-experience formula [closed]

    - by Comy
    I want to make an RPG game and I would like an advice on how should I create my level-experience formula. I saw this formula http://rsdo.net/rsdonline/guides/Experience%20formula.html#PHP and I created a formula myself and I want to ask you which would be better. RuneScape rates My rates Level 2 - 83 xp Level 2 - 35 Level 3 - 174 xp Level 3 - 84 Level 4 - 276 xp Level 4 - 150 Level 5 - 388 xp Level 5 - 238 Level 10 - 1,154 xp Level 10 - 1,087 Level 100 - 14,391,160 xp Level 100 - 311,017 As you can see at level 100 RuneScape's xp is very big and my level 100 is equal with RuneScape's Level 61. Is it better if the xp grows very fast at one point or depends on how I make my game?

  • Error accessing Gio.Gsettings on application made in quickly

I got my Gsettings schemas all set up in ~/app-name-here/data/glib-2.0/schemas/net.launchpad.app-name-here.gschema.xml correctly and I am able to access it just fine in my preferences dialog window that is located in ~/app-name-here/app-name-here/PreferencesDialog.py via from gi.repository import Gtk, Gio settings = Gio.Settings("net.launchpad.app-name-here") settings.get_boolean('notify') settings.set_boolean('notify', True) but when I try to check the value of one of my settings in a file located in ~/app-name-here/bin/Daemon.py that I use as a script to run in the background and send notifications by a similar method of from gi.repository import Gio settings = Gio.Settings("net.launchpad.app-name-here") settings.get_boolean('notify') it fails at the line that says settings = Gio.Settings("net.launchpad.app-name-here") and spits out a nasty error (Daemon.py:26100): GLib-GIO-ERROR **: Settings schema 'net.launchpad.app-name-here' is not installed Despite the fact that I can open up dconf-editor and find the settings under net/launchpad/app-name-here.

  • Are there any good html 5 mmo design tutorials? [on hold]

    Hey all. I got a rather inspired after playing gaia online's zOMG and wanted to revive an old project idea I've had laying around for a few years now. I'm looking to work with html5 (ie canvas, svg based sprites, & WebGL) to build a graphical web based MUD/MMO. Obviously, this is a new take on an old idea and after searching google I haven't really turned up many good resources. But does anyone have any tutorials or other resources to point me in the right direction?

  • Complete Guide/Tutorials on LWJGL?

    - by user43353
    Dont get me wrong, I finished these tutorials on http://lwjgl.org/wiki/index.php?title=Main_Page. I finished The Basics section, OpenGL 3.2 and newer section, and I looked at the Example Code section. They were great tutorials, and I have looked at the external tutorials as well. I don't know where to go from here, and OpenGL is not my strong point. Some one suggested Learning Modern 3D Graphics Programming, and I didnt learn much. I looked at the port to LWJGL, but the book was on C and I couldn't really understand what the OpenGL meant. I am trying to learn 2D gaming, not 3D. Maybe later. Is there any tutorials that aren't C/C++ heavy and teach you 2D OpenGL?

  • How do you handle increasingly long compile times when working with templates?

    - by Ghita
    I use Visual Studio 2012 and he have cases where we added templates parameters to a class "just" in order to introduce a "seam point" so that in unit-test we can replace those parts with mock objects. How do you usually introduce seam points in C++: using interfaces and/or mixing based on some criteria with implicit interfaces by using templates parameters also ? One reason to ask this is also because when compiling sometimes a single C++ file (that includes templates files, that could also include other templates) results in an object file being generated that takes in the order of around 5-10 seconds on a developer machine. VS compiler is also not particularly fast on compiling templates as far as I understand, and because of the templates inclusion model (you practically include the definition of the template in every file that uses it indirectly and possibly re-instantiate that template every time you modify something that has nothing to do with that template) you could have problems with compile times (when doing incremental compiling). What are your ways of handling incremental(and not only) compile time when working with templates (besides a better/faster compiler :-)).

  • How to share my wireless connection to other wireless devices

    - by user89464
    I am aware that I can share my wired internet connection to other devices wirelessly, but what I need now is a little more complex. I am limited to one device over the wifi but would like my macbook to have internet as well. It's in another room so ethernet is not really an option. I really would like to share the wireless from my ubuntu (it's on more) to other wireless devices. After some light googling I can't find anything even remotely useful as they all involve an ethernet cable at some point. Has anyone here had any luck with anything similar? I am running 12.04 LTS just for reference and have a Belkin G wireless USB device. If anyone knows a possible procedure I can find out about the chipset etc. if needed. I understand there may be hardware limitations.
