• Google Adsense threshold estimation

  - by Wladimir Ivanov

  I've an electronic music blog with traffic mainly from the North American continent, Western Europe and Russia. Daily I get about 100 unique visitors with 150-200 pageviews. Should I start Adsense or I need to work to increase the traffic stats. Can you suggest another appropriate monetizing option for the given case? How much time It would take me to hit the 100$ Adsense barrier with the given traffic statistics? Thanks in advance.

• Modify Ath9k driver and debug with aircrack-ng

  - by user4724

  I own an ALFA Adapater with Atheros AR9271. What I would like to do is to edit the driver this device uses (do some modifications in the source) and debug it. I'm really new to this, a start guide would be really appreciated. BTW, my question is similar to the question in this topic: How to modify wireless ath5k driver? but I didn't find an answer to work with (that explains the whole process) Thank you very much in advance

• USB Wifi that works with 12.04

  - by Colin Matheson

  I have done several hours of searching and I am still looking for a few USB wifi adaptors that run in 12.04 with no additional driver installations or other fiddling. I am looking to plug in the adaptor and have the laptop recognize and start connecting. We have 30 older laptops with flaky internal wifi cards so I thought that if I could find a $10-$20 USB adaptor that work reliably in 12.04 I could plug it in and solve all my connectivity problems for a few hundred dollars.

• Proactive Reputation Management and Your SEO-SEM Company

  Reputation management is often seen as necessary only when a negative publicity attack is under way. While working with an accomplished reputation management company in such circumstances can counter an attack and minimize potential damage, the best results are actually seen when companies start working with a company that will both build and protect their reputation prior to any kind of attack.

• Embedded Model Designing -- top down or bottom up?

  - by Jeff

  I am trying to learn RoR and develop a webapp. I have a few models I have thought of for this app, and they are fairly embedded. For example (please excuse my lack of RoR syntax): Model: textbook title:string type:string has_many: chapters Model: chapter content:text has_one: review_section Model: review_section title:string has_many: questions has_many: answers , through :questions Model: questions ... Model: answers ... My question is, with the example I gave, should I start at the top model (textbook) or the bottom most (answers)?

• How to boot from a debootstrap based install?

  - by João Pinto

  I would like to boot a testing Ubuntu release from a directory (which contains a debootstrap based install). As far as I understand I just need someway to tell the boot process (initrd scripts?) that it should chroot() into the specified dir immediately after mounting the root partition, and then resume the regular upstart/init start. Could someone provide some instructions on how to achieve this?

• Best way to remote restart Ubuntu from Windows machine

  - by robsoft

  Background: I'm looking to put a series of Ubuntu machines into retail locations, they're being used as dumb kiosks to show a series of slides onto large LCD panel TV screens. Once installed, they won't have a keyboard or mouse connected but will have a fixed IP on the local network. Everything is configured to auto-start, no automatic updates, no power saving etc - I think we're pretty-much good to go apart from one thing. I need the retail staff to be able to restart the boxes if a problem arises. We have VNC running (now that we've turned off desktop enhancements!) so that we can remotely get into the machines if we need to, but that's not something we would allow the retail staff to do. The machines are going to be physically 'out of the way' (probably in the ceiling space) so the power button is not easily accessible!. I'd like to have some means of allowing the retail staff to restart the Ubuntu machine, from the desktop of one of their Windows terminals. I don't really want to give them some kind of raw terminal access (the command line will frighten them!) and I don't want them to use VNC (as stated above). Ideally there would be an icon on the Windows desktop, they double-click it, reply to a simple 'are you sure?' prompt, and then the Ubuntu box is told to restart. The Windows side of that won't be a problem, we can write something using Delphi, Python & Qt4, whatever - it's the Ubuntu side of it I'm stuck with. Out of sight/view, could I have a Windows program open a terminal across the network and tell Ubuntu to restart? Is this what SSH could be used for (I have never set that kind of thing up). The Windows programming side isn't really an issue, it's just that I'm a total Ubuntu noob and don't know where to start from the platform point of view. The other thing we considered is also having the machine automatically restart itself at a set time each day (obviously out of store hours!). To me, that seems a bit unnecessary (though forcing a restart once a week/month might be worthwhile). Any thoughts or suggestions? Being able to restart the box on demand across the network is my prime requirement.

• The most dangerous SQL Script in the world!

  - by DrJohn

  In my last blog entry, I outlined how to automate SQL Server database builds from concatenated SQL Scripts. However, I did not mention how I ensure the database is clean before I rebuild it. Clearly a simple DROP/CREATE DATABASE command would suffice; but you may not have permission to execute such commands, especially in a corporate environment controlled by a centralised DBA team. However, you should at least have database owner permissions on the development database so you can actually do your job! Then you can employ my universal "drop all" script which will clear down your database before you run your SQL Scripts to rebuild all the database objects. Why start with a clean database? During the development process, it is all too easy to leave old objects hanging around in the database which can have unforeseen consequences. For example, when you rename a table you may forget to delete the old table and change all the related views to use the new table. Clearly this will mean an end-user querying the views will get the wrong data and your reputation will take a nose dive as a result! Starting with a clean, empty database and then building all your database objects using SQL Scripts using the technique outlined in my previous blog means you know exactly what you have in your database. The database can then be repopulated using SSIS and bingo; you have a data mart "to go". My universal "drop all" SQL Script To ensure you start with a clean database run my universal "drop all" script which you can download from here: 100_drop_all.zip By using the database catalog views, the script finds and drops all of the following database objects: Foreign key relationships Stored procedures Triggers Database triggers Views Tables Functions Partition schemes Partition functions XML Schema Collections Schemas Types Service broker services Service broker queues Service broker contracts Service broker message types SQLCLR assemblies There are two optional sections to the script: drop users and drop roles. You may use these at your peril, particularly as you may well remove your own permissions! Note that the script has a verbose mode which displays the SQL commands it is executing. This can be switched on by setting @debug=1. Running this script against one of the system databases is certainly not recommended! So I advise you to keep a USE database statement at the top of the file. Good luck and be careful!!

• How do I get into Facebook game development?

  - by Ben Zeigler

  I have some ideas that I think might make interesting games for a Facebook-like platform, in that they are social and casual. Does anyone have advice on how to get into Facebook development from a background in traditional C++ game development? Is there anything special that differentiates developing facebook games from developing other web-based games, such as API intricacies and so forth? To start with this will probably be hobbyist level instead of some sort of professional enterprise, anything I need to know about making indie-level facebook games?

• Code Analysis Rule Sets in Visual Studio 2010

  - by Anthony Trudeau

  Microsoft Visual Studio 2010 introduces the concept of rule sets when configuring code analysis.  This is a valuable change from Visual Studio 2008 that I didn't even realize I wanted.  Visual Studio 2008 by default selected all rules and then you had to remove rules on an item by item basis. The rule sets fall into logical groups including "Microsoft All Rules", "Microsoft Basic Correctness Rules", "Microsoft Security Rules", et al.  And within the project properties you can select one rule set, multiple rule sets, or you can define your own rule set based upon another. Selecting a single rule set is obviously the easiest option.  The default rule set when you create a new project is the "Microsoft Minimum Recommended Rules".  However, in my opinion the recommended rules are just too permissive.  For that reason you might want to change your rule set to "Microsoft All Rules" until you get around to creating your own rule set; or alternately you can select multiple rule sets which is an option from the rule set combo box.  The Visual Studio documentation has comprehensive help on what is contained within the rule sets. Creating your own rule set is easy if not obvious.  You need to start a rule set from an existing rule set.  To get started select a rule set in the combo box within the Code Analysis tab of the project properties.  I selected the "Microsoft All Rules" for my rule set, but you may find it easier to start with the "Microsoft Minimum Recommended Rules" if your rules are on the more permissive side. Once your rule set is selected click the Open button.  This will display a dialog that is similar in composition to the rules selection from Visual Studio 2008.  Browsing through the tree view you can select or deselect individual rules within their categories; and you can indicate that the rules are flagged as errors instead of the default which is a warning.  A nice touch to the form is that you get a help pane when you select an individual rule.  That helped me considerably when I first configured my rule set. Once you have finished selecting your rules click the Save tool button, specify a location and name, and click the Save button on the Save As dialog.  Once you're back on the Code Analysis tab you'll choose the Browse option within the combo box and open the file you just created.

• Startup a Ubuntu FTP and SSH server without logging in

  - by Jenko

  I have a Ubuntu Server 11.10 box, which I would like to run "headless", and without a keyboard, mouse or display. Is it possible that immediately after startup the machine logs into an account, or allows me to control the machine from my Windows 7 machine nearby via SSH and SFTP? I've got OpenSSH server installed, and even when the box is not logged in I can start an SSH session. I've tried installing VSFTPD but its very troublesome (hardly connects) and only starts when I login locally into the box.

• How to handle interruptions in developer work without losing concentration? [closed]

  - by tomaszs

  I work as a developer for some years now. Mainly the issue why it's antisocial work is because you need to spend much time programming. I've been always the kind of developer who likes to cut off from any sources of distraction and spend several hours on project because in this way i (as i hope) do it faster. There are also other kinds of developers, more social that can chat, read, watch movies while development and they are ok with this and don't hesitate to be interrupted in their work in any time and come back to the project without any problem. For me any distraction is source of frustration because i need to spend substantial time to load my mind with all info about the project and to concentrate back on the tasks. I always thought it's better to do this that way because project is completed faster. But it makes some things difficult: it's hard to chat with someone who needs to have some important info: because you are a bit frustrated when you know you loose your Zen. And sometimes its more important to chat with someone than to loose Zen. Well.. mostly in any other kind of work the ability to be "multitask" is very important. But as a developer and as a person it's also very important to stay social. And i see now that the problem of concentration makes it difficult to make the right chose: the cost of maintaining concentration is just sometimes so damn high! So is it only me that i have so little concentration skills so any interruption is for me a big deal? Maybe it's just i have so bad memory so that i dont remember all issues of a project so long? Or maybe i develop the project in a fashion that requires me to store so much info on my mind only to be able to start working with code? Or should i just accept that being more social will make me finish project slower and in the fashion that i personally consider non 100% productive? And it's just normal thing and i should just accept it and start to live like any other person who has many works and don't assume that programming is in any case other than any other work and i just do fuzz about the whole concentration thing? This is question for mid-pro developers. I think you was having the same dillema in your life. I would be glad if you could help me take the right road here because it's just driving me and i suppose people i work with crazy for years.

  A DBA's huge workload can start to threaten best practices for data backup and recovery, but ingenuity, and an eye for a good tactic, can usually find a way. For Tom, the revelation about a solution came from eating crabs. Statistical sampling can be brought to bear to minimize the risk of failure of an emergency database restore.

• USB Drive Warm Boot Issue. Cold boot = Perfect. Warm boot = "No boot sector found on USB device"

  - by Dan

  I'm experiencing a boot/reboot quirk similar to, yet somewhat different from others posted here. I have two Western Digital "Passport" external USB2 drives (160GB and 320GB) with Ubuntu 11.10 installed. The BIOS on my laptop is set to boot USB drives before the internal drive, and it works well. Either drive will cold-boot Ubuntu 11.10 perfectly. However, at times the computer must be restarted (warm boot) to have software updates or other changes take effect. When I warm-boot the computer, the computer goes through its normal shutdown/restart, then the usual BIOS tests, at which time the USB drive is selected momentarily (as normal), and that's when the trouble starts. I get a "No boot sector found on USB device", and the computer proceeds to boot Windows from the internal drive. If I press F12 early during the restart sequence (allows manual selection of the boot sequence), USB is still shown before the internal drive on the sequence list (as it should be). If I highlight "USB" and press ENTER, I still get a "No boot sector..." error message, but the external USB drive then proceeds to boot Ubuntu normally. I have a third external USB drive (Western Digital 160 GB Media Center) that cold-boots and warm-boots perfectly, so I know everything in the computer is set up properly. It also tells me Ubuntu is set up correctly on the drives, as all three drives were done identically, and at the same time. I've tried formatting the Passport drives NTFS and FAT32, but it didn't change anything. If I power-down the computer, then start it up again, it will boot Ubuntu from either of the Passport drives perfectly - every time. It's as if during a warm boot the Passport drives are somehow looking for the boot loader in the wrong location on the drive - yet either drives works when booting from a cold start. Not a show-stopper .. but frustrating. Computer is a Dell XPS M1530, A12 BIOS (latest), but I don't think the computer plays into the issue because one of the three drives works at all times. It's only the two WD Passport models at issue here. Thanks!

• cloud programming for OpenStack in C / C++

  - by Basile Starynkevitch

  (Sorry for such a fuzzy question, I am very newbie to cloud programming) I am interested in designing (and developing) a (free software) program in C or C++ (probably, most of it being meta-programmed, i.e. part of the C code code being generated). I am still in the thinking / designing phase. And I might perhaps give up. For reference, I am the main architect and implementor of GCC MELT, a domain specific language to extend the GCC compiler (the MELT language is translated to C/C++ and is bootstrapped: the MELT to C/C++ translator being written in MELT). And I am dreaming of extending it with some cloud computing abilities. But I am a newbie in cloud computing. (I am only interested in free-software, GPLv3 friendly, based cloud computing, which probably means openstack). I believe that "compiling on the cloud with some enhanced GCC" could make sense (for super-optimizations or static analysis of e.g. an entire Linux distribution, or at least a massive GCC compiled free software like Qt, GCC itself, or the Linux kernel). I'm dreaming of a MELT specific monitoring program which would store, communicate, and and enhance GCC compilation (extended by MELT). So the picture would be that each GCC process (actually the cc1 or cc1plus started by the gcc driver, suitably extended by some MELT extension) would communicate with some monitor. That "monitoring/persisting" program would run "on the cloud" (and probably manage some information produced by GCC e.g. on NoSQL bases). So, how should some (yet to be written) C program (some Linux daemon) be designed to be cloud-friendly? So far, I understood that it should provide some Web service, probably thru a RESTful service, so should use an HTTP server library like onion. And that OpenStack is able to start (e.g. a dozen of) such services. But I don't have a clear picture of what OpenStack brings. So far, I noticed the ability to manage (and distribute) virtual machines (with some Python API). It is less clear how can it distribute some ELF executable, how can it start it, etc. Do you have any references or examples of C / C++ programming on the cloud? How should a "cloud-friendly" (actually, OpenStack friendly) C/C++ server application be designed?
