• Where can I hire local programmers with very specific skillsets?

  - by Lostsoul

  I have been browsing the site and haven't found a exact fit to this question so I'll post it but if its already answered(since I'm sure its a common problem, then let me know). I have a business and want to create a totally different product in a different industry than I'm currently in, so I learned how to program and created a working prototype. I have a bit of savings and am getting some cash flow from my current business so I can go out and hire a developer(in the future hopefully it can be permenant but right now I just need a person willing to work on contract and code on weekends or their spare time and I just want to pay in cash instead of equity or future promises). At first I wasn't sure what kind of developer to hire but this question helped me understand I should target specific skills I need as opposed to general programmers. This poses a problem for me since general programmers are everywhere but if I want specific skills I'm unsure how to get them. I thought about a list of approaches but it doesn't feel complete or effective since it seems to be assuming good developers are actively looking. If it helps I want someone local(since this is my first developer hire) and looking for skills like cuda, hadoop, hbase, java and c. Any suggestions? As a FYI, I have been thinking of approaching it as: Go to meet ups for one or more skills I need. Use LinkedIn to find people with the skills I need Search for job postings that contain skills I need and then use linkedIn to reach out to that firms employees since many profiles on linkedin are not very updated or detailed but job postings generally are. Send postings to universities and maybe find a student who loves technology so much they learned these tools on their own. Post on job board. Not sure how successful it will be to post to monster. Use Craigslist, not sure if a highly skilled developer would go here for work. What am I missing? I could be wrong but it seems like good/smart/able developers aren't hunting for work non-stop(especially in this tech job market). Plus most successful people I know have work/life balance so I'm not sure if the best ones really care about code after work. Lastly, most of the skills I need aren't used in big corporations so not sure how aggressively smart developers at small shops look for work. I don’t really know any developers personally, so but should I be using the above plan or if they live balanced lives should I be looking outside of the regular resources(and instead focus on asking around my gym or my accountant or something)? Sorry, I'm making huge assumptions here, I guess because developers are a total mystery to me. I kind of wish Jane Goodall wrote a book on understanding developers social behaviour better :-p

• My ubuntu partition was deleted and I can't boot from either a DVD or USB

  - by ropudito

  It's my first time installing ubuntu. I have Windows 7 and 8 before in my laptop (Acer Aspire 4752z). After Ubuntu (12.04) installed in my laptop, the Windows boot loader didn't recognize my Ubuntu so I updated grub from a live USB. And after grub updated, Ubuntu was booting perfectly but my Windows wasn't listed in the grub menu. So I follow someone instruction to update grub again. And after reboot, the grub menu didn't show anymore. After searching about this problem on the net and trying to update grub again and again, I decided to delete the Ubuntu partition from live USB. And shortly after, I booted to Windows with Hiren boot and I used mbrfix. But i think it failed. Now i cant show my BIOS setup or boot from DVD or USB. After that, the only screen i can see after booting is: error: unknown filesystem grub rescue>

• Worth changing the URL structure to incorporate keywords?

  - by Dejan Pelzel

  I am migrating my blog from PHP to ASP.NET and while recoding the whole website, I figured I might as well improve the URL structure. This is how an url looks like now: example.com/blog/post/755/hakurei-reimu-cosplay-from-touhou-by-kishigami-hana and this is hould it will look after the change (cosplay being the dynamic main keyword of the post): example.com/blog/cosplay/hakurei-reimu-cosplay-from-touhou-by-kishigami-hana-755/ The website is a bit more than a half year old and receives around 650k page views a month, mainly from search traffic. Of course everything would be redirected with 301 redirects. Do you think it is worth changing to a new URL structure, or will it harm the ranking in the long run?

• Multi-platform Map Application

  - by Mahdi

  I'm working on a web project (PHP, jQuery) which currently using Google Maps powering up the map functionality of the application, however we need to make it multi-platform like you can go to the dashboard and choose one from 5-10 map providers (which Goolge Maps is just one of them) to underlying your map functionality. So, as the application is supposed to show the data on map, almost in every single place we have to deal with the API provided by that specific map provider. Currently we are thinking about revising our modular structure and/or making something like an adapter for each provider to deal with their native syntax but via our standard methods. I wish to have your ideas and your experiences, specially if you ever made an interface for dealing via 2-3 different map providers. That would helps much and I really appreciate that. If you need any further information, just ask me to update the question. Update: As Vicky Chijwani suggested Mapstraction, now I'm also wondering which one is more better (pros & cons), having an adapter implemented on Javascript or PHP?

• New computer hangs on shutdown/reboot, how to troubleshoot?

  - by torbengb

  Summary: My machine hangs on shutdown/restart: all windows and the menu bar disappear but the desktop wallpaper remains, and it stays like that without disk activity forever (hours). It doesn't even show the shutdown screen (the one with the animated dots) where I could hit ESC and watch the shutdown text. How can I troubleshoot this? Details: I've just received a new nettop computer (Acer Aspire Revo 3700: CPU:Atom D525, GPU:Nvidia ION2). I've just made a clean install of Ubuntu 10.10 using the standard USB pendrive method. The machine boots okay and works OK including WLAN and audio, but the graphics are not OK. Ubuntu offered to install&activate the current recommended Nvidia driver, but the machine hangs on shutdown/restart which prevents the installation of the proper Nvidia driver. I have to cycle the power to reboot. I ran the Update Manager in the hope that the updates would fix the hang-up. At the end of the update-installation it asked to reboot - and got stuck just like before. I see no obvious cause of the freeze and I don't know if it's caused by graphics problems or anything else. The only USB attachment is a mouse/keyboard; I don't have any external storage attached; and I don't have any programs running (the machine freezes even when doing restart right after login). How can I determine what is causing the freeze? How can I fix this? I'm frankly rather disappointed because I bought this new machine in the hopes of getting the graphics to work, which failed miserably on my old machine, even though Ubuntu is supposed to be good with Nvidia. Being a fresh convert from Windows, I was hoping for a happier experience this time, so I'm very much looking forward to your suggestions! ... After posting this question, I see related questions in the right sidebar: this, this, and this. Don't know why these didn't show up while I composed by question. Those questions suggest some ACPI settings but I am not experienced enough to find/change those settings. I'll try the sudo shutdown -h now command when I get home and see if that works, then update this question. I did check the system BIOS but didn't see anything out of the ordinary.

• Linux repository contains latest tools for synaptic

  - by William.Ebe

  I'm using backTrack5R3. And I 've installed Synaptic as well as ubuntu Software center. Synaptic is very easy to use and gives wide range of details for the packages that I'm going to download. But the problem is it lack of lot of new files and information. Like vlc or adobe reader. The latest stable version of vlc is 2.0. but synaptic only installs, 1.1. And it don't find adobe. I would like to get new versions of them. What is the best way/source to update new files? EDIT: I mean after performing update & upgrade synaptic still contains vlc 1.0.6 which is outdated. I'm looking for a way to get new/best source.

• sprite animation system height recalculating has some issues

  - by Nicolas Martel

  Basically, the way it works is that it update the frame to show every let's say 24 ticks and every time the frame update, it recalculates the height and width of the new sprite to render so that my gravity logics and stuff works well. But the problem i am having now is a bit hard to explain in words only, therefore i will use this picture to assist me The picture So what i need basically is that if let's say i froze the sprite at the first frame, then unfreeze it and freeze it at the second frame, have the second frame's sprite (let's say it's a prone move) simply stand on the foothold without starting the gravity and when switching back, have the first sprite go back on the foothold like normal without being under the foothold. I had 2 ideas on doing this but I'm not sure it's the most efficient ways to do it so i wanna hear your inputs.

• Is it needed to have your blog title and description in H1 and H2

  - by Saif Bechan

  I have read an article that states that it is not necessary to have your blog title and description on your website at all. Just have the titles of the posts in h1, on the index and the post page. And on the post page have your different sections started with h2. Widget headers start with h3. Title and description are most of the time in the logo image. I have looked at the source of my favorite blog, http://net.tutsplus.com, and I see they do the same. Is this recommended?

• Complete RESTful API debugging/testing tool

  - by vartec

  I'm looking for the most complete tool, preferably portable GUI or browser plugin to test RESTful API. What I need is: GET/POST/DELETE/PUT support multiple file uploads as fields (multipart/form-data) file uploads as body Extra points for: possibility to save multiple configurations and use them to pre-fill parameters OAuth support nice JSON response formatting Currently I'm using 3 tools: Chrome REST Console extension — My favorite, very nicely done. Has OAuth. However the functionality missing for me is sending file as a body of the request; Cannot send multiple files; Firefox Poster add-on — Quite nice, but the functionality it's missing for file as POST fields parameters; Also cannot send multiple files; cURL — can do anything, but it's quite tedious to use it from command line.

• Using multiple diagrams per model in Entity Framework 5.0

  - by nikolaosk

  I have downloaded .Net framework 4.5 and Visual Studio 2012 since it was released to MSDN subscribers on the 15th of August.For people that do not know about that yet please have a look at Jason Zander's excellent blog post .Since then I have been investigating the many new features that have been introduced in this release.In this post I will be looking into theIn order to follow along this post you must have Visual Studio 2012 and .Net Framework 4.5 installed in your machine.Download and install VS 20120 using this link.My machine runs on Windows 8 and Visual Studio 2012 works just fine. I have also installed in my machine SQL Server 2012 developer edition. I have also downloaded and installed AdventureWorksLT2012 database.You can download this database from the codeplex website.   Before I start showcasing the demo I want to say that I strongly believe that Entity Framework is maturing really fast and now at version 5.0 can be used as your data access layer in all your .Net projects.I have posted extensively about Entity Framework in my blog.Please find all the EF related posts here. In this demo I will show you how to split an entity model into multiple diagrams using the new enhanced EF designer. We will not build an application in this demo.Sometimes our model can become too large to edit or view.In earlier versions we could only have one diagram per EDMX file.In EF 5.0 we can split the model into more diagrams.1) Launch VS 2012. Express edition will work fine.2) Create a New Project. From the available templates choose a Web Forms application  3) Add a new item in your project, an ADO.Net Entity Data Model. I have named it AdventureWorksLT.edmx.Then we will create the model from the database and click Next.Create a new connection by specifying the SQL Server instance and the database name and click OK.Then click Next in the wizard.In the next screen of the wizard select all the tables from the database and hit Finish.4) It will take a while for our .edmx diagram to be created. When I select an Entity (e.g Customer) from my diagram and right click on it,a new option appears "Move to new Diagram".Make sure you have the Model Browser window open.Have a look at the picture below 5) When we do that a new diagram is created and our new Entity is moved there.Have a look at the picture below  6) We can also right-click and include the related entities. Have a look at the picture below. 7) When we do that the related entities are copied to the new diagram.Have a look at the picture below  8) Now we can cut (CTRL+X) the entities from Diagram2 and paste them back to Diagram1.9) Finally another great enhancement of the EF 5.0 designer is that you can change colors in the various entities that make up the model.Select the entities you want to change color, then in the Properties window choose the color of your choice. Have a look at the picture below. To recap we have demonstrated how to split your entity model in multiple diagrams which comes handy in EF models that have a large number of entities in them Hope it helps!!!!

• The future is looking brighter &ndash; debugging Windows Azure in the cloud with IntelliTrace

  - by Eric Nelson

  One of the “warts” on Windows Azure development has been that once your application was deployed to the cloud, if things went wrong it was pretty tough to figure out the root problem. I knew for sometime we had a solution coming for Visual Studio 2010 users and I couldn’t wait to tell folks about it once it became public. I planned to do a detailed post subsequent to briefly mentioning it when I talked about the 1.2 SDK release. However … other stuff just keeps on getting in the way. Hence I have decided to point at Somas blog post on just that. Enjoy. Check out Peering into the cloud with IntelliTrace  NB: You will need the Ultimate Edition of Visual Studio 2010 to use this feature. Sorry.

• TFS 2008 to TFS 2010 moves and some issues

  - by Enrique Lima

  There have been many things going on this year around TFS.  Most of them had to do with migrations (I don’t call them upgrades for the most part since it involved new hardware and such).  Many were implementations using the Conchango SfTS template (now EMC). But there were others that were CMMI or Agile 4.0. Everything would move just fine, no issues.  That was until you attempted to run Test Case Management or run the last configuration steps for Lab Management. There is an error that states a project is not ready to run or integrate with Test or Lab Management.  And while there was some documentation on how to adjust and update the Agile WITs to work with it, there was still some disconnect to making it work with CMMI. Now there is a great post on how to run the “fix” from end to end. Check the post here:  TFS 2010: Enable Test Case Management for upgraded Team Projects

• A programming language that does not allow IO. Haskell is not a pure language

  - by TheIronKnuckle

  (I asked this on Stack Overflow and it got closed as off-topic, I was a bit confused until I read the FAQ, which discouraged subjective theoratical debate style questions. The FAQ here doesn't seem to have a problem with it and it sounds like this is a more appropriate place to post. If this gets closed again, forgive me, I'm not trying to troll) Are there any 100% pure languages (as I describe in the Stack Overflow post) out there already and if so, could they feasibly be used to actually do stuff? i.e. do they have an implementation? I'm not looking for raw maths on paper/Pure lambda calculus. However Pure lambda calculus with a compiler or a runtime system attached is something I'd be interested in hearing about.

• How to disable framebuffer in initramfs in 14.04 server?

  - by Blangero

  Recently I'm working on ubuntu 14.04 server. While using plymouth, I have late splash and tried to fix it, I googled and got lots of suggestions on doing this: vi /etc/initramfs-tools/conf.d/splash and add: FRAMEBUFFER=y and update-initramfs -u After doing this, I got no splash at all.So I deleted the FRAMEBUFFER=y and re-update initramfs, splash came back. But after that I installed something, maybe it's remastersys or n86v or their dependencies, or something else, I got splash gone again and according to the boot.log, I think it's due to framebuffer enabled in initramfs again. I tried FRAMBUFFER=n in /etc/initramfs-tools/conf.d/splash but failed. Now I got no splash and still can't get it back. Does anyone know how to disable framebuffer in initramfs? Thanks a lot!

• concurrency::index<N> from amp.h

  - by Daniel Moth

  Overview C++ AMP introduces a new template class index<N>, where N can be any value greater than zero, that represents a unique point in N-dimensional space, e.g. if N=2 then an index<2> object represents a point in 2-dimensional space. This class is essentially a coordinate vector of N integers representing a position in space relative to the origin of that space. It is ordered from most-significant to least-significant (so, if the 2-dimensional space is rows and columns, the first component represents the rows). The underlying type is a signed 32-bit integer, and component values can be negative. The rank field returns N. Creating an index The default parameterless constructor returns an index with each dimension set to zero, e.g. index<3> idx; //represents point (0,0,0) An index can also be created from another index through the copy constructor or assignment, e.g. index<3> idx2(idx); //or index<3> idx2 = idx; To create an index representing something other than 0, you call its constructor as per the following 4-dimensional example: int temp[4] = {2,4,-2,0}; index<4> idx(temp); Note that there are convenience constructors (that don’t require an array argument) for creating index objects of rank 1, 2, and 3, since those are the most common dimensions used, e.g. index<1> idx(3); index<2> idx(3, 6); index<3> idx(3, 6, 12); Accessing the component values You can access each component using the familiar subscript operator, e.g. One-dimensional example: index<1> idx(4); int i = idx[0]; // i=4 Two-dimensional example: index<2> idx(4,5); int i = idx[0]; // i=4 int j = idx[1]; // j=5 Three-dimensional example: index<3> idx(4,5,6); int i = idx[0]; // i=4 int j = idx[1]; // j=5 int k = idx[2]; // k=6 Basic operations Once you have your multi-dimensional point represented in the index, you can now treat it as a single entity, including performing common operations between it and an integer (through operator overloading): -- (pre- and post- decrement), ++ (pre- and post- increment), %=, *=, /=, +=, -=,%, *, /, +, -. There are also operator overloads for operations between index objects, i.e. ==, !=, +=, -=, +, –. Here is an example (where no assertions are broken): index<2> idx_a; index<2> idx_b(0, 0); index<2> idx_c(6, 9); _ASSERT(idx_a.rank == 2); _ASSERT(idx_a == idx_b); _ASSERT(idx_a != idx_c); idx_a += 5; idx_a[1] += 3; idx_a++; _ASSERT(idx_a != idx_b); _ASSERT(idx_a == idx_c); idx_b = idx_b + 10; idx_b -= index<2>(4, 1); _ASSERT(idx_a == idx_b); Usage You'll most commonly use index<N> objects to index into data types that we'll cover in future posts (namely array and array_view). Also when we look at the new parallel_for_each function we'll see that an index<N> object is the single parameter to the lambda, representing the (multi-dimensional) thread index… In the next post we'll go beyond being able to represent an N-dimensional point in space, and we'll see how to define the N-dimensional space itself through the extent<N> class. Comments about this post by Daniel Moth welcome at the original blog.

• Java : une vulnérabilité découverte dans le correctif d'urgence publié par Oracle, pouvant produire les mêmes dommages

  Faille de sécurité critique dans Java 7 Update 6 pouvant être utilisée pour installer des malwares, la désactivation de la plateforme recommandée Les experts en sécurité tirent la sonnette d'alarme pour la dernière version de la plateforme Java. Java 7 Update 6 serait sujet à une vulnérabilité activement exploitée. Les chercheurs en sécurité du cabinet FireEye ont découvert une faille de sécurité dans la plateforme pouvant être exploitée pour infecter des ordinateurs avec des logiciels malveillants. La vulnérabilité aurait été utilisée pour installer à distance le cheval de Troie Poison Ivy, qui a été utilisé dans le passé dans de nombreuses campagnes de cyberespionnage. L...

• Exclude category from Wordpress home page unless it belongs to another category

  - by sirlancelot

  I have multiple users adding content to restricted categories (using RoleScoper) in my Wordpress setup that don't show up on the homepage (custom template with query_posts()). I'm looking for a way to "promote" the submitted content to the homepage by adding it to another category. My loop code looks like this: <?php query_posts($query_string . '&cat=-37'); if (have_posts()): while (have_posts()): the_post(); ?> This will exclude all posts in category 37. However, even if I add the post to a different category it still gets excluded. Is there a way to exclude a post if it belongs to just that one category?

• Access Control Management Tool ACM.exe

  - by kaleidoscope

  The Access Control Management Tool (Acm.exe) is a command-line tool you can use to perform management operations (CREATE, UPDATE, GET, GET ALL, and DELETE) on the AppFabric Access Control entities (scopes, issuers, token policies, and rules). Basic Syntax The command line for Acm.exe follows the basic pattern of verb-noun. For example: acm.exe <command> <resource> [-option:<option value>] This tool will automatically generate random keys, which helps ensure that they can't easily be guessed by an attacker. Note that ACM.EXE is a thin wrapper around a REST Web Service (the AC management service). That helps to remember the commands it accepts, which are the typical resource management commands for a REST service: · Get(All) · Create · Update · Delete ACM.EXE.config file can be used to configure Host, Service and the Management key for a Service Namespace.

• How to change address and name of the computer in linux Ubuntu

  - by Byakugan

  I have troubles again after upgrading Linux to version 12.04 - When I try to update progams and files with "apt-get update" it says something like there is no address added to your computer name. So my hostname has name "Marco" and my hosts file has line "127.0.0.1 Marco" So where is problem? Where should I change my name to get it right for updates? Thank you. Before on version 11.10 it was working fine. W: Failed http://en.archive.ubuntu.com/ubuntu/dists/precise-updates/main/i18n/Translation-en Something bad happened in the translation "en.archive.ubuntu.com: http" (-5 - The machine name is not assigned to any address)

  How do you have the grub appear on a key combination, but have windows boot default. I'm running ubuntu 11.10 and grub 2.0. Here is my current /etc/default/grub # If you change this file, run 'update-grub' afterwards to update # /boot/grub/grub.cfg. # For full documentation of the options in this file, see: # info -f grub -n 'Simple configuration' GRUB_DEFAULT=0 GRUB_HIDDEN_TIMEOUT=0 GRUB_HIDDEN_TIMEOUT_QUIET=true GRUB_TIMEOUT=10 GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian` GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" GRUB_CMDLINE_LINUX=" quiet vga=769" Thanks!

• Bridging LXC containers to host eth0 so they can have a public IP

  - by Vianney Stroebel

  UPDATE: I found the solution there: http://www.linuxfoundation.org/collaborate/workgroups/networking/bridge#No_traffic_gets_trough_.28except_ARP_and_STP.29 # cd /proc/sys/net/bridge # ls bridge-nf-call-arptables bridge-nf-call-iptables bridge-nf-call-ip6tables bridge-nf-filter-vlan-tagged # for f in bridge-nf-*; do echo 0 $f; done But I'd like to have expert opinions on this: is it safe to disable all bridge-nf-*? What are they here for? END OF UPDATE I need to bridge LXC containers to the physical interface (eth0) of my host, reading numerous tutorials, documents and blog posts on the subject. I need the containers to have their own public IP (which I've previously done KVM/libvirt). After two days of searching and trying, I still can't make it work with LXC containers. The host runs a freshly installed Ubuntu Server Quantal (12.10) with only libvirt (which I'm not using here) and lxc installed. I created the containers with : lxc-create -t ubuntu -n mycontainer So they also run Ubuntu 12.10. Content of /var/lib/lxc/mycontainer/config is: lxc.utsname = mycontainer lxc.mount = /var/lib/lxc/test/fstab lxc.rootfs = /var/lib/lxc/test/rootfs lxc.network.type = veth lxc.network.flags = up lxc.network.link = br0 lxc.network.name = eth0 lxc.network.veth.pair = vethmycontainer lxc.network.ipv4 = 179.43.46.233 lxc.network.hwaddr= 02:00:00:86:5b:11 lxc.devttydir = lxc lxc.tty = 4 lxc.pts = 1024 lxc.arch = amd64 lxc.cap.drop = sys_module mac_admin mac_override lxc.pivotdir = lxc_putold # uncomment the next line to run the container unconfined: #lxc.aa_profile = unconfined lxc.cgroup.devices.deny = a # Allow any mknod (but not using the node) lxc.cgroup.devices.allow = c *:* m lxc.cgroup.devices.allow = b *:* m # /dev/null and zero lxc.cgroup.devices.allow = c 1:3 rwm lxc.cgroup.devices.allow = c 1:5 rwm # consoles lxc.cgroup.devices.allow = c 5:1 rwm lxc.cgroup.devices.allow = c 5:0 rwm #lxc.cgroup.devices.allow = c 4:0 rwm #lxc.cgroup.devices.allow = c 4:1 rwm # /dev/{,u}random lxc.cgroup.devices.allow = c 1:9 rwm lxc.cgroup.devices.allow = c 1:8 rwm lxc.cgroup.devices.allow = c 136:* rwm lxc.cgroup.devices.allow = c 5:2 rwm # rtc lxc.cgroup.devices.allow = c 254:0 rwm #fuse lxc.cgroup.devices.allow = c 10:229 rwm #tun lxc.cgroup.devices.allow = c 10:200 rwm #full lxc.cgroup.devices.allow = c 1:7 rwm #hpet lxc.cgroup.devices.allow = c 10:228 rwm #kvm lxc.cgroup.devices.allow = c 10:232 rwm Then I changed my host /etc/network/interfaces to: auto lo iface lo inet loopback auto br0 iface br0 inet static bridge_ports eth0 bridge_fd 0 address 92.281.86.226 netmask 255.255.255.0 network 92.281.86.0 broadcast 92.281.86.255 gateway 92.281.86.254 dns-nameservers 213.186.33.99 dns-search ovh.net When I try command line configuration ("brctl addif", "ifconfig eth0", etc.) my remote host becomes inaccessible and I have to hard reboot it. I changed the content of /var/lib/lxc/mycontainer/rootfs/etc/network/interfaces to: auto lo iface lo inet loopback auto eth0 iface eth0 inet static address 179.43.46.233 netmask 255.255.255.255 broadcast 178.33.40.233 gateway 92.281.86.254 It takes several minutes for mycontainer to start (lxc-start -n mycontainer). I tried replacing gateway 92.281.86.254 by : post-up route add 92.281.86.254 dev eth0 post-up route add default gw 92.281.86.254 post-down route del 92.281.86.254 dev eth0 post-down route del default gw 92.281.86.254 My container then starts instantly.
