  • Web Host for Small Rails-based CMS site [closed]

    - by clem
    Possible Duplicate: How to find web hosting that meets my requirements? I am building a site for someone that uses a Rails-based content management system that I built myself. All of the Rails deployment experience I have so far has been over small intranets. I'm looking at web hosts like rackspace, because it seems like they're well-suited for Rails deployment. However, for a site that's not going to have more than a couple of hundred hits a month (if even that), I'm not sure it's necessary. I've also used Dreamhost's Phusion Passenger deployment for small projects before, but it seems barely functional and not well-supported, and I've also used Heroku for deployment, but I think a regular web host may do a little bit better, as they'll need things like Google Apps for Gmail set up. If anyone could provide some guidance on this, I'd greatly appreciate it. I get confused when I see things on rackspace like "1.5c/hour", because I'm not sure how that gets computed.

  • What is the difference between "Redirection" and "Pipe"?

    - by John Threepwood
    This question may sound a bit stupid, but I can not really see the difference between redirection and pipes. Redirection is used to redirect the stdout/stdin/stderr, e.g. ls > log.txt. Pipes are used to give the output of a command as input to another command, e.g. ls | grep file.txt. But why are there two operators for the same thing ? Why not just write ls > grep to pass the output through, isn't this just a kind of redirection also ? What I am missing ?

  • Rules for Naming

    - by PointsToShare
    © 2011 By: Dov Trietsch. All rights reserved Naming Documents (or is it “Document, Naming”?) Tis but thy name that is my enemy; Thou art thyself, though not a Montague. What's Montague? It is nor hand, nor foot, Nor arm, nor face, nor any other part Belonging to a man. O, be some other name! What's in a name? That which we call a rose By any other name would smell as sweet; So Romeo would, were he not Romeo call'd, Retain that dear perfection which he owes Without that title. Romeo, doff thy name And for that name which is no part of thee Take all myself.  Shakespeare – Romeo and Juliet Act II, Scene 2 We normally only use the bold portion of the famous Shakespearean quote above, but it is really out of context. As the play unfolds, we learn that a name is all too powerful. Indeed it is because of their names that the doomed lovers die. There might be life and death in a name (BTW, when I wrote this monogram, I was in Hatfield, PA. Remember the Hatfields and the McCoys?) This is a bit extreme, but in the field of Knowledge Management (KM) names are of the utmost importance as well. When I write an article about managing SharePoint sites, how should I name it? “Managing a site” or “Site, managing”? Nine times out of ten I’d opt for the latter. Almost everything we do is “Managing” so to make life easier for a person looking for meaningful content, we title our articles starting with the differentiator rather than the common factor. As a rule of thumb, we start the name with the noun rather than the verb. It is not what we do that is the primary key; it is what we do it to. So, answer this – is it a “rule of thumb” or a “thumb rule?” This is tough. A lot of what we do when naming is a judgment call. Both thumb and rule are nouns, albeit concrete and abstract (more about this later), but to most people “thumb rule” is meaningless while “rule of thumb” is an idiom. The difference between knowledge and information is that knowledge is meaningful information placed in context. Thus I elect the “rule of thumb”. It is the more meaningful title. Abstract and Concrete are relative terms. Many nouns (and verbs) that are abstract to a commoner, are concrete to a practitioner of one profession or another and may even have different concrete meanings in different professional jargons. Think about “running”. To an executive it means running a business, to a marathoner its meaning is much more literal. Generally speaking, we store and disseminate knowledge within a practice more than we do it in general. Even dictionaries encyclopedias define terms as they apply to different audiences. The rule of thumb is to put the more concrete first, but within the audience’s jargon. Even the title of this monogram is a question. Do I name it “Naming Documents” or “Documents, Naming”? Well, my own rule of thumb (“Here he goes again!?”) states that the latter is better because it starts with a noun, but this is a document about naming more than it about documents. The rules of naming also apply to graphs and charts, excel spreadsheets, and so on. Thus, I vote for the former.  A better title could have been “Naming Objects” only the word “Object” is a bit too abstract. How about just “Naming” or “Naming, rules of”? You get the drift. One of the ways to resolve all of this is to store the documents in Knowledge-Bases, which may become the subjects of a future punditry. Knowledge bases use keywords to describe their content.  Use a Metadata store for the keywords to at least attempt some common grounds. Here is another general rule (rule of thumb?!!) – put at least the one keyword in the title. Use subtitles. Here is an example: Migrating documents – Screening, cleaning, and organizing our knowledge. The main keyword is “documents”, next is “migrating”, other keywords also appear in the subtitle. They are “screening”, “cleaning”, and “organizing”. Any questions? Send me an amply named document by email: [email protected]

  • GRUB2 panic: "No such partition"

    - by Android Eve
    I managed to install 10.04 on a system that already has 8.04 (separate partitions, of course). It also installed GRUB2 onto the MBR. After discovering that there is no menu.lst anymore, I edited /etc/grub.d/40_custom to point to where my other OS partitions are: menuentry "Ubuntu 8.04" { set root=(hd0,0) linux /boot/vmlinuz-2.6.24-28-generic initrd /boot/initrd.img-2.6.24-28-generic } menuentry "Windows 7 Ultimate 64-bit" { set root=(hd0,2) chainloader (hd0,2)+1 } GRUB2 displays the menu with those entries but when I select any of them, it refuses to load them, saying "No such partition". I know the partitions are there, as 10.04's "Disk Utility" sees them without any problem. How do I get GRUB2 to recognize them?

  • migrating from struts2, looking for a new framework

    - by adhg
    We are supposed to start a relatively big project that will require lots of computation and analysis. Presentation (UI) for the end user is very crucial (graphs, tabels...) So far we've been using struts2. It's ok+. It has some drawbacks (specially if you work with tiles and all that XML) but if you get the lingo - you're ok. One option on the table is to continue using struts2 with jquery and all the other stuff that we've been doing for so long. Alternatively, I think we have an opportunity to learn something new and maybe a bit better then struts2. My question is this: Anyone has migrated from struts2 to something new and can share the experience. Or had some great experience witha particular java framework. Many thanks for any pointers.

  • How In-Memory Database Objects Affect Database Design: Hybrid Code

    - by drsql
    In my first attempts at building my code, I strictly went with either native or on-disk code. I specifically wrote the on-disk code to only use features that worked in-memory. This lead to one majorly silly bit of code, used to create system assigned key values. How would I create a customer number that was unique. We can’t use the Max(value) + 1 approach because it will be very hideous with MVCC isolation levels, since 100 connections might see the same value, leading to lots of duplication. You...(read more)

  • 3D Modeling Software for Programmer [closed]

    - by Pathachiever11
    I've recently learned how to make games for Unity3d, and now I want to start making games! I can't wait to start! However, before I can make 3D games, I need to learn 3D modeling for character design, level design, and some animation. What is the easiest 3D modeling software, compatible with Unity3d? I do not want to spend too much time learning the software. From what I've heard, Blender is a bit complicated to use. Maya and 3dsMax seem very powerful. Could someone point me in the right direction? I don't want to spend a lot of time learning. I know its not that easy, but you guys have experience, you guys probably know out of all which one is easier and powerful. Could you recommend a software? Many Thanks!

  • Placing of copyright notice in source code

    - by Diana Dcn
    I'm about to release a project of mine that I'm really proud of under the GNU GPL and I have some questions: Should one attach a copyright notice on each and every source code file from their project? I think it's a bit ridiculous to claim copyright on a 3 line abstract class. Should I attach a copyright notice only to really important source code files? Can I not attach the whole standard thingy? Because it's big and bulky and gets in the way... If so, is the variant below ok/enough? Copyright year firstname lastname.

  • 12.04 - how to install alsa 1.0.27, to resolve dell sound card microphone echo issue to local speaker?

    - by YumYumYum
    Problem: Microphone in or Line in microphone audio is instantly captured and sinked to the local speaker, cause horrible echo problem About my system: (NO PulseAudio used (cause its always crash and unstable for my system/hardware, so auto killed and never used) I have ALSA 1.0.25 version running in Ubuntu 12.04 / 64-bit, with random kernel installed: kernel 3.5.0-17-generic kernel 3.8.x kernel 3.11.x But the echo problem is not resolved after trying all kernel. So, last option left now is to use ALSA 1.0.27 to see if that solves the problem. Is there any away to use ALSA 1.0.27 from any PPA to install in the Ubuntu 12.04? (without making it from source, to avoid breaking other packages and dependencies)

  • trying live-usb 12.04.1 image on an old desktop

    - by 213441265152351
    I am trying to load Ubuntu 12.04.1 32-bit desktop image on an old desktop computer. The system shows the initial menu, but after a while, I get an error like the one in the following two screenshots (it takes a few seconds to go from one to the other in the screen): I tried to load it using the different USB ports at the back of the computer, just in case, and I get basically the same error. Find another screenshot from another try: Any ideas what might be happening? NOTES: I checked the md5sum of the iso file to be e235b63c02644e219b7bf3668f479c9e *ubuntu-12.04.1-desktop-i386.iso. I did the 'Test' on the laptop where I created the USB drive, and it loads up correctly. The desktop computer in question is an old AMD Duron 1800MHz with 512MB RAM. I ran a memtest on the computer, and all went fine.

  • Techniques and methods to improve and speedup development

    - by Jlouro
    I just got a new project. It’s a WinForm app. And it’s interesting because I will have the possibility to learn how fish farms work and are managed. I will have to develop touch interfaces, and use datasnap to communicate and sync data between farm and office. The development will be done in DELPHI win32, still not sure about the database, but maybe SQLlite. So now comes the difficult part of the project, building it. I am just finishing one. It took me a lot of time to do it and I am a bit “burned out”. I will have time to relax, not much, but a few days. What I am looking is some tips and tricks and possibly tools to be able to speed up the development. It must be up and running in 2 months. So what tricks do you use to speed up things?

  • Why does 12.04 freeze when using multiple desktops?

    - by Dustin
    I am using 12.04 32-bit, upgraded from 11.10. Within the last week and a half Unity has hung on me with no option but a hard reboot, which I hate. It usually happens when I am using multiple desktops and applications and switching desktops. The screen just hangs, sometimes broken between desktops and applications, I can move my mouse but cannot click on anything. alt+f2 , HUD , super+w/s/d and alt+tab/~ does nothing, they do not activate. I let it rest for 15-20 minutes in hopes it will sort itself out but nothing. I'd hate to move to Unity 2D, but I can't risk having to do hard reboots/shutdowns, or moving to a different DE. Other information: the only PPA's I have added recently would be the word lens. 2.8GB RAM processor : 0 vendor_id : AuthenticAMD cpu family : 15 model : 127 model name : AMD Sempron(tm) Processor LE-1250 stepping : 2 microcode : 0x83 cpu MHz : 1000.000

  • How to spot a good social media marketer

    - by fiftyeight
    It's a bit subjective but helpful and on-topic IMO, mayebe should be made community wiki I've been in contact with some guest bloggers lately which are interested in publishing posts on my website's blog, so far I've done a regular weekly blog and had a guy marketing it, but he's too busy to do more work right now. Now I need someone to market these blog posts on social media, the last guy I just got by recommendation from a friend, but now I need to find one myself. What criteria should I check when it comes to social media marketers? Do the number of followers and fans on their accounts and/or the number of votes they get for articles they market mean anything, or is impossible to know if it's spam? That's about the only criterion I could think of so far... Thanx to anyone who helps

  • Laptop buttons not working on a Dell Latitude e6400

    - by Ido
    I have install Ubuntu 12.10 64 bit on my Dell Latitude E6400 laptop. I have the latest bios version for my laptop (A32) which I downloaded from the official Dell website by checking updates that matches the service tag on my laptop. I'm having serious problems with all the mouse buttons on my laptop. The right-click button doesn't work at all under any circumstance. The left click button only work when clicking on icons in the left side-bar and in the top menu (like clicking on the power icon in the top-right corner or clicking on the file menu). However none of the buttons work in any of the applications even simple one like the file browser (home folder). For example when I try to click on a folder inside nautilus it doesn't work or when I try to click on the "x" close icon to close the window it also doesn't work. Can you help me figure it out?

  • Cannot login via Unity login screen after upgrade to 12.04

    - by codesurgeon
    Logging in via the shell accessed through Ctrl+Alt-F1 and logging in as guest via the graphical user interface work 0O When I try to log into my standard user account via the graphical interface, the screen flashes to black for a couple of seconds and bumps me back to a pristine login screen. Entering a wrong password for my user account yields the standard error message - my user account and credential verification seem to be OK. I suppose that my individual graphics configuration causes problems ... I'm not sure how to reset that. I've tried stopping the UI via sudo service lightdm stop executed sudo nvidia-xconfig and restarted the UI sudo service lightdm start to no avail. My workstation has a Nvidia GeForce 560-448 graphics card. I've tried getting this fixed with the latest Nvidia 64-bit drivers (cURL'ed from the official website), that is 295.49 and the latest beta driver 302.07. Anybody have an idea how to get this fixed? Your help is appreciated :)

  • Pair programming remotely with Visual Studio?

    - by shamp00
    What tools exist to facilitate pair programming with Visual Studio when the programmers are not in the same physical location? At the moment we are thinking voice (Skype?) plus remote desktop (VNC? TeamViewer?), but it would be good to know of other suggestions and experiences. Also, is there anything more integrated with Visual Studio? A bit more background: we are two experienced developers with who have collaborated well for a long time on a large mature project (ASP.NET, Windows Forms and SQL Server). However we are not usually working on the same part of the code base at the same time. We intend to spend some weeks doing substantial refactoring and it would be ideal if we were able to do this work with a pair-programming approach.

  • Setting up ASP.NET structure for code

    - by user1175327
    I've always coded in C# MVC3 when developing web applications. But now i wanted to learn a bit more about developing web sites with just ASP.NET. But now i'm wondering what a good setup for my code would be. For me, an MVC like pattern seems to be a good way to go. But obviously ASP.NET doesn't have any router and controller classes. So i guess people have a different way of setting up their code when they do ASP.NET. So i'm looking for more information on how to get started with this. So not really the basics of ASP.NET, but something that focuses on a good code setup. Any good tutorials/information about this/?

  • Anti aliasing problem

    - by byronyasgur
    I am auditioning fonts on google web fonts and one that I was discounting was Ubuntu because it looked a bit jagged ( screenshot below taken straight from google); however afterward I read an article where it was mentioned as a good choice, and there was a screenshot where it looked really good ( to me anyway ). I am using windows 7 and have tried looking at it in chrome and firefox. I notice the same thing with some other fonts but this one is a good example because it looks perfect in the screenshot but not so good when I look at it on their site. I know this essentially is a question about setting my computer, but I thought that this would be the best place to pose the question: Is there something wrong with the settings on my machine seeing as it's obviously not showing the font the same on my computer as it did when the article writer downloaded it and used it in an image. The screenshot from Google ... The screenshot from the article above ...

  • From Transactions To Engagement

    - by David Dorf
    I've mentioned in the past that Oracle has invested quite a bit in acquiring social companies to build out its Social Relationship Management suite.  The concept is to shift away from transactions and towards engagement.  Social media represents a great opportunity to engage with customers, learn what they want, and personalize the shopping experience for them. I look at SRM as the bridge between traditional CRM and CX.  If you're looking for ideas, check out Five Social Retailing Suggestions and Social Analytics and the Customer.  There are lots of ways to leverage social media to enhance the customer experience and thus drive more sales. My friends over at 8th Bridge have just released their Social IQ report in which they rate retailers on their social capabilities.  They also produced a nice infographic so you can consume the data quickly, but I'd still encourage you to download the full report. Retailers interested in upping their SRM abilities should definitely stop by the Oracle booth at NRF in January.
