• Ubuntu 12.04 takes too long to boot

  - by msPeachy

  I've recently encountered the following error message: mount: mounting /dev/disk/by-uuid/3f7f5cd9d-6ea3-4da7-b5ec-**** on /root failed: Invalid argument mount: mounting /sys on /root/sys failed: No such file or directory mount: mounting /dev on /root/dev failed: No such file or directory mount: mounting /sys on /root/sys failed: No such file or directory mount: mounting /proc on /root/proc failed: No such file or directory Target file system doesn't have /sbin/init. No init found. Try passing init= bootarg. Busybox v1.18.5 (Ubuntu 1:1.18.5-1ubuntu4) built-in shell (ash) Enter 'help' for a list of built-in commands. (initramfs) _ I run sudo fsck /dev/sda2 which is the Ubuntu ext4 root partition via LiveCD. It checked and fixed the file system. The next time I boot, Ubuntu started to load with the Ubuntu logo and the dots underneath for several hours (with the mouse pointer active on the screen), I even let the computer on overnight but still it did not successfully boot or got to the login screen in the morning. I booted again with the LiveCD and checked the NTFS partitions with ntfsfix and again the NTFS partitions was checked and fixed successfully. I also edited my fstab and commented out the lines that auto-mounts the NTFS partitions. The next time I boot, it took almost 20 minutes for Ubuntu to get to the login screen, after typing the password it took an additional 10 minutes for Ubuntu to get to the desktop. On the desktop, it take several minutes to open any program, displaying the Dash alone takes 5 minutes! Is there a fix for this without having to reinstall Ubuntu? I don't see or get any errors, Ubuntu is just taking too long to boot and to run programs. Please help!

• Do i need to restore iptable rules everytime on boot?

  - by capdragon

  Every time i reboot i loose the iptables rules that took me sooo long to enter. I know i can save them and restore them on boot but is there anyway to save them forever? Do i really need to restore them on boot every time? Seriously? The problem is I have a HUGE list of IPs in which i use a while loop to load them in. This can take upwards of 10 minutes. This is my home FTP server. It's a small vm with 1gb ram and very little processing power. There are so many IPs because I've pretty much given up on the Asian continent. I don't need them to be hitting up my ftp server everyday with brute force. I also block gov. monitors, trackers and spammers. This is the while loop i use to load in the list. grep INPUT block.list | while read LISTA; do sudo iptables -A $LISTA; done

• What language available on commodity web hosts would suit a C# developer? [closed]

  - by billpg

  Recognising its ubiquity on commodity web hosting services, I tried developing in PHP a few years ago. I really didn't like it, later deciding that life was too short for PHP. (In brief, having to put $ on variable names; mis-spelt variable names become new variables; converting non-numeric strings to integers without complaint; the need for an "and this time I mean it" comparison operator.) In my ideal world, commodity web hosts would all support C#/ASP.NET, my preferred web-development language and framework, but this is not my ideal world. Even Mono has barely made a dent on Linux based hosts. However, last time I moaned about PHP's ubiquity, someone followed up that this was no longer the case, and that many other languages are now commonly usable on web hosts too. What programming language; a. Would suit a developer who prefers C#. b. Is available to run on many web hosts.

• Is The Ease Of Windows Phone Development Ruining Its Image

  - by Tim Murphy

  I was reading an article on Mashable recently by a long time iPhone user who is living solely on a Lumia 920 at the moment and giving her assessment.  One thing that struck a nerve with me was her describing the Windows Phone ecosystem as immature.  She wasn’t saying this because of the number of apps or the big names like most people do.  She means the quality of the apps in the store. This hit a nerve with me.  I find it hard to believe that the majority of app on iOS are of any higher quality than any other platform.  I believe in any ecosystem you are going to find some high end, high quality apps, but the majority by default will be from people who are trying to solve a problem but do not have the resources to have top graphics and full blown testing.  There will also be a large number that are just there trying to trick you into giving up some cash. Does any of the mean that we shouldn’t take notice of this complaint?  Of course not!  We should always strive to publish the best quality apps possible.  Don’t do things like leaving default app icons and backgrounds.  Put a little effort into your design.  You should also spend as much time as possible ensuring against crashes and giving the user the best experience possible.  Think through your apps organization and navigation.  Go the extra step of putting it into beta and letting select people use it and give you feedback before going to full release. Remember, if we want people to appreciate the Windows Phone platform we have to make sure we give them apps that they are going to enjoy using. del.icio.us Tags: Windows Phone,iPhone,iOS,Nokia,Lumia 920,Mashable

• Partition tool with console UI (as in server installation)?

  - by lepe

  Back in 2006, Ray (3DLover) posted the same question in: http://ubuntuforums.org/showthread.php?t=309680 but none of the answers were really useful. Now with a little help from AskUbuntu community, I would like to repeat his question again to see if this time it can be answered correctly. So this is the question (and what I wish too): I'm looking for a UI tool for managing partitions in a console. I have installed Ubuntu Server, so I don't have X Windows at all. fdisk and sfdisk are entirely command line. parted is slightly better, but it's not really a UI. cfdisk has somewhat of a UI, but it only works on one disk at a time, and there's no advanced options like configuring LVM or RAID. Just partitioning. I love the partition tool that is available during the OS install procedure. You can partition, configure RAID's and LMV sets. It can format the partitions with several different file systems, it can set labels, mount options and it can insert your volumes into your fstab. Is this tool available as a stand-alone program? I can't find it anywhere. I think it's called parted_server, but I can't find much information about where to get it. In the past, I have run the Ubuntu install procedure just to use the partition manager that comes with it. (canceling the install after making my partition edits) Anyone help me on this? Thanks -Ray Thanks in advance.

• Lots of Internet browsing issues, all browsers

  - by dario_ramos

  Before the upgrade, everything was working fine. Now, however, I can connect to the Internet but a lot of stuff fails, and the weirdest thing is that it happens with Firefox, Chromium and Opera. Some of the things that fail: I can't log in to Stack Overflow, after entering user/pass it loads for a long time on Firefox and throws Error 408 (browser request timed out) on Chromium and Opera I can't log in to Hotmail, similar symptoms I can login to Facebook, but when I try to write a comment, or just post something in my wall, it stays loading for a long time, and then fails The first two issues seem to be related to secure pages, and the second one is another issue altogether, I believe. However, they all happen with all browsers, which is really weird. Talking about weird: I connect using a Huawei SmartAX MT 810 USB modem, which cost me blood and tears to get it working under Ubuntu. I ordered an ethernet modem/router with my ISP, and I'm still waiting, but this issue intrigues me anyway. Has anyone experienced this kind of problems? I Googled around, but couldn't find a similar case.

• Is it okay to use a language that isn't supported by your company for some tasks?

  - by systempuntoout

  I work for a company that supports several languages: COBOL, VB6, C# and Java. I use those languages for my primary work, but I often find myself to coding some minor programs (e.g. scripts) in Python because I found it to be the best tool for that type of task. For example: An analyst gives me a complex CSV file to populate some DB tables, so I would use Python to parse it and create a DB script. What's the problem? The main problem I see is that a few parts of these quick & dirty scripts are slowly gaining importance and: My company does not support Python They're not version controlled (I back them up in another way) My coworkers do not know Python The analysts have even started referencing them in email ("launch the script that exports..."), so they are needed more often than I initially thought. I should add that these scripts are just utilities that are not part of the main project; they simply help to get trivial tasks done in less time. For my own small tasks they help a lot. In short, if I were a lottery winner to be in a accident, my coworkers would need to keep the project alive without those scripts; they would spend more time in fixing CSV errors by hand for example. Is this a common scenario? Am I doing something wrong? What should I do?

• How to avoid the GameManager god object?

  - by lorancou

  I just read an answer to a question about structuring game code. It made me wonder about the ubiquitous GameManager class, and how it often becomes an issue in a production environment. Let me describe this. First, there's prototyping. Nobody cares about writing great code, we just try to get something running to see if the gameplay adds up. Then there's a greenlight, and in an effort to clean things up, somebody writes a GameManager. Probably to hold a bunch of GameStates, maybe to store a few GameObjects, nothing big, really. A cute, little, manager. In the peaceful realm of pre-production, the game is shaping up nicely. Coders have proper nights of sleep and plenty of ideas to architecture the thing with Great Design Patterns. Then production starts and soon, of course, there is crunch time. Balanced diet is long gone, the bug tracker is cracking with issues, people are stressed and the game has to be released yesterday. At that point, usually, the GameManager is a real big mess (to stay polite). The reason for that is simple. After all, when writing a game, well... all the source code is actually here to manage the game. It's easy to just add this little extra feature or bugfix in the GameManager, where everything else is already stored anyway. When time becomes an issue, no way to write a separate class, or to split this giant manager into sub-managers. Of course this is a classical anti-pattern: the god object. It's a bad thing, a pain to merge, a pain to maintain, a pain to understand, a pain to transform. What would you suggest to prevent this from happening?

• SharePoint Saturday Huntsville Wrap Up

  - by Mark Rackley

  So, Cathy Dew (@catpaint1) and company put on a great SharePoint Saturday event this past weekend. I got to hang out with some old friends and meet some new ones. I’d list you all, but I’d undoubtedly miss someone and don’t want to offend anyone.  Although I find it odd that I see @MossLover now more since she moved to New Jersey than when she lived next door in Kansas City… what’s up with that? Anyway, Cathy did a tremendous job organizing the event.  Everything went smoothly and everyone had a great time. Maybe I can talk her into organizing the rest of SharePoint Saturday Ozarks on June 12th… you know that’s coming up? right? While you’re here why not go ahead and register right now at: http://spsozarks.eventbrite.com/  Yes.. that was a shameless plug… I did my default presentation on “Wrapping Your Head Around the SharePoint Beast”. This continues to be my most popular presentation. I try to tweak it every time and I always have fun doing it. I get to pick on people and they pick on me back, but I always manage to learn something new when I present it. I had a great interactive crowd and they didn’t throw anything at me.  All in all I consider it a success.  Thanks for coming if you attended!  You can get the slides here:  SharePoint Saturday Huntsville - Wrapping Your Head Around the SharePoint Beast Next up for me is SharePoint Saturday DC on May 15th.  Wow this is going to be a huge event with space for 1500 attendees.. no, that is not a typo!  Stop me and say hi if you are able to make it!!

• Ubuntu 11.10 won't let me login; it kicks me back to login screen

  - by zlyfire

  I was just copying files from my external HDD to my .wine directory, when I noticed the place where the launchers are (Unity desktop) was getting fuzzy and holding onto graphics from the things in the location prior(i have it autohide when a window covers it). I assumed it was just RAM problem, so I canceled the copying, since it wasn't actually important. The glitch remained, and so did another; very slow response time. The mouse moved just fine, but windows were waiting about a minute after I hit the x button to close or even switch active window. Once again, I blamed RAM (only have 2 GBs) so I restarted. Usually, it autologs me into my account, since I'm the only user, but this time it presented me with the login screen. I thought it odd, but tried to log in. A black screen with some text pops up (assuming terminal screen) for half a second then kicks me back to the login screen. I tried the guest account and no luck. I went into terminal (alt+ctrl+f1) and logged in and it worked. I deleted .Xauthority, made new account, and even rebooted quite a few times, all to no avail. Anyone have an idea?

• Designing communications for extensibility

  - by Thomas S.

  I am working on the design stages of an application that will a) collect data from various sources (in my case that's scientific data from serial ports), keeping track of the age of the data, b) generate real-time statistics (e.g. running averages) c) display, record, and otherwise handle the data (and statistics). I anticipate that I will be adding both data producers and consumers over time, and would like to design this application abstractly so that I will be able to trivially add functionality with a small amount of interface code. What I'm stumbling on is deciding what communication infrastructure I should use to handle the interfaces. In particular, how should I make the processed data and statistics available to multiple consumers? Some things I've considered: Writing to several named pipes (variable number). Each consumer reads from one of them. Using FUSE to make a userspace filesystem where a read() returns the latest line of data even if another process has already read it. Making a TCP server, and having consumers connect and request data individually. Simply writing the consumers as part of the same program that aggregates the data. So I would like to hear your all's advice on deciding how to interface these functions in the best way to keep them separate and allow room for extenstions.

• Bug: unable to handle kernel NULL pointer dereference at

  - by maria

  I have recently installed new system on my disc, Ubuntu 12.04. Installation proceeded without problems, I started installing additional software and put data from other discs. I had already two times bug report, it was quite long, and I have no idea how to acces to log file (which probably is somewhere saved) and since I had to switch off the computer using the button, anything else was possible, here is just a small part of it (what I've noted on paper) could not write bytes: Broken pipe speach dicpatcher disabled: edit etc/default/speach-dispatcher saned disabled: edit .... and than: BUG: unable to handle kernel NULL pointer dereference at 0000009c I've run Memory test in GRUB, everything is fine. First time it occured when I was using rsync, second time when I was trying to install texlive. Should I install whole system once again? Or can it be hardware problem? Or something else? If there is any hardware details which may be relevant, please ask, since I have no idea what is happening, I don't know what kind of information could be useful. Thanks P.S. dmesg output:

• Error on /home prevents OS boot

  - by mdrg

  Ok, I'll try to explain it listing the events: motherboard battery is weak, loses config everytime I shut the PC down; system clock usually back to 1990-something; this time, it went up to 2148; ubuntu became somewhat unusable (firefox refusing certificates, dropbox blocked), so I restarted; manually set the clock to current date and restarted; during boot, ubuntu detects errors and start auto-fix, rebooting itself in the middle of it (like a hard reboot, no shutdown messages) next time, shows boot animation screen in text mode, with an error message after a while: "Errors were found while checking the disk drive or /home", with "attempt to fix, ignore, skip mounting or manual recovery" None of the options during the boot work, they just type the text to the screen, then I'm forced to physically restart. Now I'm using Mint LXDE live CD, and I can see all my partitions just fine, including /home (my home folder blocked due to encryption, the other user folder is accessible and everything in place). I'm not sure how to proceed now. I'd like to just fix ubuntu boot without reinstalling or anything like it (at least until 12.04). What should I do now? can I easily fix this somewhow? Thanks!

• Patients are Running out of Patience

  - by Naresh Persaud

  Healthcare is in a dramatic state of change globally and the change is being driven by patients. Patients are no longer content to wait in line, endure appointment delays and stay on hold waiting for a health insurance representative. Instead, patients are demanding on-line access to physicians, joining communities with fellow patients, scheduling appointments online and resolving claims issues over email.  To accomodate the demand for patient connectivity, providers are innovating to find new ways to collaborate with patients. To address the demand, providers are providing 24/7 access online and pioneering ways to deliver care via mobile devices -  for example using your iPhone as a heart monitor. Patient vitals can be collected before the patient even walks into the clinic.  These new approaches promise to enhance the patient experience and reduce the cost of care. Time is money both for the patient and the provider. For insurance companies, all of this is  welcome news because it reduces un-necessary time with the physician which reduces the number of claims.  Oracle is focused on enabling and securing the experience. The video below shares the Oracle healthcare transformation story. asas

• Broadcom 4313 doesn't work following 12.04 upgrade

  - by Lucas

  I have an hp G62-228Ca laptop with a BCM4313 previously running Ubuntu 11.10. I ran the 12.04 upgrade last night without much thought. Following the upgrade and mandatory reboot, the wireless card no longer shows up in the network manager, the first time I've had any kind of issues with wireless under Ubuntu. I've done much Googling on the issue but so far I haven't found a permanent solution. Mucking around with some packages though (I've installed five different ones or so), I've managed to devise a workaround that I must run every time I boot the laptop. I have to remove the Broadcom STA driver and reinstall it. Inspiration taken from here: WiFi does not work, Broadcom STA Wireless driver does not work on a BCM4313 After the second modprobe command, the wireless reappears in the network manager and ten seconds after that I'm back on the wifi. If anyone can provide some advice on how to fix this permanently I will be extremely grateful. I'd rather not roll back to 11.10 or reinstall, but I will if I need to. Just let me know if you need the output from any terminal commands. Thanks in advance!

• Upon Reflection

  - by foxjazz

  During my tenure at the last company, I didn't let my career stagnate as others have and as time moved along.When at work or home, spend 10% of your time learning something new about some aspect or segway of your job so that your skills are marketable in case you lose it. From experience let me reinforce that it pays off. It pays off in your current job because of the education received and the competence increase of your skills which applied will bring recognition.In these days and times, loyalty to a company is truly at an end. However many companies do care about cultivating their employees which creates a brand of loyalty that can't be replaced. Old companies with the Corp. mentality (or because of the corp. mentality) ever decrease their budgets on organizational sections and thereby do a RIF as a matter of business.The mistakes they make during this process can be risky. But who am I, but a lowly ole programmer, to judge risk. If you are laid off, be friendly with your past manager, and based on simple questions and help, give whatever help you can over the phone even though you are under no obligation to do so.It is also quite possible that there are opportunities to make at home with a new company in the future. Just remember that when inquiring about a position, take advantage of the training that is offered, and keep yourself emotionally and educationally fit.Talk soon,foxjazz

• What is a good way to refactor a large, terribly written code base by myself? [closed]

  - by AgentKC

  Possible Duplicate: Techniques to re-factor garbage and maintain sanity? I have a fairly large PHP code base that I have been writing for the past 3 years. The problem is, I wrote this code when I was a terrible programmer and now it's tens of thousands of lines of conditionals and random MySQL queries everywhere. As you can imagine, there are a ton of bugs and they are extremely hard to find and fix. So I would like a good method to refactor this code so that it is much more manageable. The source code is quite bad; I did not even use classes or functions when I originally wrote it. At this point, I am considering rewriting the whole thing. I am the only developer and my time is pretty limited. I would like to get this done as quickly as possible, so I can get back to writing new features. Since rewriting the code would take a long time, I am looking for some methods that I can use to clean up the code as quickly as possible without leaving more bad architecture that will come back to haunt me later. So this is the basic question: What is a good way for a single developer to take a fairly large code base that has no architecture and refactor it into something with reasonable architecture that is not a nightmare to maintain and expand?

• Allowing client to select data to return via REST interface

  - by CMP

  I have a rest service that is essentially a proxy to a variety of other services. So if I call GET /users/{id} It will get their user profile, as well as order history, and contact info, etc... all from various services, and aggregates them into one nice object. My problem is that each call to a different service has the potential to add time to the original request, so we would rather not get ALL the data ALL of the time if a particular client does not care about all of the pieces. A solution I have arrived at is to do something like this: GET /users/{id}?includeOrders=true&includeX=true&includeY=true... That works, and it allow me to do only what I need to, but it is cumbersome. We have added enough different data sources that there are too many parameters for that style to be useful. I could do something similar with a single integer and a bitmask or something, but that only makes it harder to read, and it does not feel very Restful. I could break it down into multiple calls so they would need to call /users/{id}/orders and /users/{id}/profile separately, but that sort of defeats the purpose of an aggregating proxy, who's purpose is to make clients jobs easier. Are there any good patterns that can help me return just enough data for each client, without making it too difficult for them to filter and select what they want?

• How can I make my PHP development environment more efficient?

  - by pixel

  I want to start a home-brew pet project in PHP. I've spent some time in my life developing in PHP and I've always felt it was hard to organize the development environment efficiently. In my previous PHP work, I've used a windows desktop machine and a linux server for development. This configuration had it's advantages: it's easy to configure Apache (and it's modules)/PHP/MySql on a linux box, and, at the time, this configuration was the same like on production server. However, I never successfully set up a debug connection between my Eclipse install and X-debug on server. Transferring files from my local workspace to the server was also very annoying (either ftp or Bazaar script moving files from repository to web root). For my new setup, I'm considering installing everything on my local machine. I'm afraid that it will slow down workstation performance (LAMP + Eclipse), and that compatibility problems will kick-in. What would you recommend? Should I develop using two separate machines? On one? Do you have experience using one of above configurations in your work?

• Korea&rsquo;s Anti Abortion / Pro Life Movement

  - by Randy Walker

  The South Korean government is in dire straits.  The national birth rate continues to decline and as the population grows older, there aren’t enough children being born to support the country long term.  The social issues of post Korean War are coming back to haunt the empowered nation.  Being torn apart by the Korean War (nicknamed the forgotten war in America) and with a nation facing starvation, South Korea allowed hundreds of thousands of their children to be adopted abroad.  This has created a problem of epidemic proportions, essentially devaluing life in Korea and child rearing. In an effort to encourage birth rates, the government encouraged their workers to go home early and procreate by turning off the lights in buildings.  Something unknown to me, was the illegalization of abortion except in special cases. According to the this article, http://joongangdaily.joins.com it’s working.  Abortions are down and women are being encouraged to give birth.  However the flip side is illegal risky abortions are on the rise, with potential back alley abortions looming.  But with a nation facing it’s potential implosion, it has to continue it’s efforts to encourage mothers to give birth. Many of the issues that America has faced is in stark contrast to South Korea.  Abortion has been a generally accepted procedure for some time.  If you’ll recall, I mentioned South Korea devalued their children.  But the nation’s problems lie so much deeper.  Being an Asian nation, saving “face” is an important aspect of life.  And being an unwed mother disgraces the family.  Living as a single mother in South Korea is a difficult life.  Most married mothers stay at home to take care of the children.  Being a shunned single mother that has a hard time getting a job (because you are a single mother) and affording child care isn’t like life in America. If we in the states suddenly faced a birthrate crisis, what would the U.S. government do?

• F# &ndash; Converting your C# brain to the F# way

  - by MarkPearl

  My brain still thinks in C#!!! I have been looking at F# and trying to figure out the basics of it, but all the time in the back of my mind I am going – what is the C# equivalent to this or that… It’s frustrating because I almost want a F# to C# dictionary the whole time – and simply translate my C# code to F# – which would negate the main motivation for learning F# – as I want learn functional programming - if I was simply doing C# code in a F# syntax I would be gaining nothing! So I am experiencing pain while my brain forms some new neural networks… but luckily I live in a country where we have 11 official spoken languages, and plenty more unofficial languages so I have gone through the pain of learning how to speak a new language before – and I am finding the process is almost identical in learning a programming language that promotes a different way of looking at problems (from Object Orientated to Functional). That beings said… the first thing to learn is the basic syntax… I have searched the web for appropriate places to get a translation – and have been quite disappointed with what is out there for F#. Luckily, OCaml came to the rescue. There are some really good tutorials on getting started with OCaml syntax, one in particular that stood out was the OCamal-Tutorial. What I particularly like about it is that it is doing comparisons between C based languages and OCaml. Give it a read sometime – it’s well worth it and has definitely helped me understand F# a little better.
