• How will I know when my company is ready to receive an investment? [migrated]

  - by gunshor

  How will I know when my company is ready to receive an investment? I am starting a company and have bootstrapped it so far. I have produced four versions of the demo. The first fully-working version is underway. Getting this to a beta phase product will require capital, which requires an investment, which requires an investor, which requires I stop working on the product and go out and talk to people about it. The last time I raised money from investors, it took a while but I was successful. I don't want it to take a while. I want it to be brain dead simple for an investor to understand the value so that I can optimize the time I spend with the product. Is my logic flawed? What is the best way to approach raising money, while limiting both my time and risk? Thanks.

• New "How do I ..." series

  - by Maria Colgan

  Over the last year or so the Optimizer development team has presented at a number of conferences and we got a lot of questions that start with "How do I ...". Where people were looking for a specific command or set of steps to fix a problem they had encountered. So we thought it would be a good idea to create a series of small posts that deal with these "How do I" question directly. We will use a simple example each time, that shows exactly what commands and procedures should be used to address a given problem. If you have an interesting "How do I .." question you would like to see us answer on the blog please email me and we will do our best to answer them! Watch out for the first post in this series which addresses the problem of "How do I deal with a third party application that has embedded hints that result in a sub-optimal execution plan in my environment?"

• Black screen with blinking cursor after dual boot install 14.04

  - by chillstream

  I have just installed Ubuntu 14.04 on my toshiba laptop along side Windows 7. When the menu comes up to choose which OS to boot into, I can easily boot into Windows 7. I cannot successfully boot into Ubuntu. All I get is a blinking cursor on a black/purple screen. I attempted the nomodeset trick, which was a bit more successful. I got a screen with a lot of code, but then it stopped with a blinking cursor at the bottom and wouldn't load anymore. As a last resort, would returning my laptop to factory settings get rid of linux and the partitions made to the drive? I already did this to my laptop when it was just windows, which is why I thought I might as well try to add Ubuntu. But it's a lengthy process, and if it won't get rid of the partitions and ubuntu, I won't bother. I appreciate any help ~many thanks

• Unit testing multiple conditions in an IF statement

  - by bwalk2895

  I have a chunk of code that looks something like this: function bool PassesBusinessRules() { bool meetsBusinessRules = false; if (PassesBusinessRule1 && PassesBusinessRule2 && PassesBusinessRule3) { meetsBusinessRules= true; } return meetsBusinessRules; } I believe there should be four unit tests for this particular function. Three to test each of the conditions in the if statement and ensure it returns false. And another test that makes sure the function returns true. Question: Should there actually be ten unit tests instead? Nine that checks each of the possible failure paths. IE: False False False False False True False True False And so on for each possible combination. I think that is overkill, but some of the other members on my team do not. The way I look at it is if BusinessRule1 fails then it should always return false, it doesn't matter if it was checked first or last.

• Best way to manage a changelog

  - by Gnial0id

  I'm currently developing a WinForm application. In order to inform the client about the improvements and corrections made during the last version, I would like to manage and display a changelog. I mostly found existing changelog on website (the term changelog is pretty used) or explanation on how to manage the release numbers, which I don't care. So, these are my questions: Is there a good practice in changelog management (using XML, pure text in the app, etc.) in a desktop application ? What is the best way to display it (external website, inside the winform application) ? Thanks.

• Will modem manager be updated in 12.04 LTS to release 0.6.0 or above by Canonical?

  - by user204045

  It is still stuck at release 0.5.2 since early last year, while release 0.6.0 does not seem to be progressed to a stable release for 12.04 LTS. Any plans for the update to occur before the end of the year? In a related but separate question, I note that the latest Modem Manager GUI (0.0.16) has now been released for Saucy Salamander in its Software Center, but still with the older 0.0.13 version for Precise's Software Center - why does it not follow suit? Perhaps Mathieu Trudel-Lapierre or Graham Inggs can offer some help with answers if no one else can? Thanks in advance!

• 12.04 Software "RAID 0" on desktop replacement, 2 HDD?

  - by gregzeng

  Hardware: HP Pavilion DV7 notebook: 8GB DDR3, 2x 750GB SATA2 HDD, I7 c+ Radeon GPU, eSATA, Bluray, etc. Currently multiboot with Win7-64 + choice of 5 'buntu-64. Prefer Xubuntu-64-alternate, but not able to install software RAID-0 at the last active partition on both HDDs. Tried many types: real boot partition, etc. All my Linux op sys boot successfully from the extended partitions on both drives, but without RAID of any kind. Theory - yes. But has anyone really succeeded with 12.04 software RAID-0?

• Strange behaviour when screencasting

  - by Luis Alvarado

  Since an update I did yesterday I am not able to screencast any video using Kazam, Recordmydesktop or even ffmpeg/aviconv. After the upgrade to some libraries (A normal update that showed in Update manager) the problem was this: When doing the screencast, scrolling inside an Apps window like Firefox, Chrome or Gedit is not shown. The video only shows the last image it recognized before I started scrolling. For example with Gedit, I have a lot of text on it and when I start to scroll down, the video only shows what I had in the beginning while I listen to myself talk about what is in the rest of the file (Which is not shown in the video). When opening a window, for example again Gedit or Chrome it might not show in the video, it will just show the desktop without the window opened. I do not see any error with dmesg, syslog or others. What can I check to debug this problem?

• CSS not loading when site is viewed via Windows VPN

  - by Dreamling

  Internal site has recently been redesigned, but IE8 does not seem to be loading the new css rules only when viewed via VPN. I really have no clue what to look for. I can't reproduce the problem, but it's apparently affecting client for the last month. I've suggested: Reloading IE8 Checking Internet Permissions Flushing the cache I'm not really certain what direction to search for the answer. Is it likely to be a server permissions issue? a VPN connection issue? a rare ie8 CSS bug?

• How to patch libgphoto2 for preview pictures in Shotwell while importing?

  - by Erraticus

  Under some circumstances, Shotwell shows no photo thumbnails while importing. I was trying to download some pictures from my camera (Canon EOS 400D) with Shotwell and the program didn't show any preview for the pictures before downloading them (it just shows a "forbidden" snapshot). After importing them everything seems fine. I've found this bug report but no solution is given for now. It seems there could be a solution for EOS cameras, according to the last comment. This guy links to a patch, but it's not downloadable. Any ideas of where to obtain a deb package of this patch or of any other solution?

• Ubuntu 12.10 64b does not shutdown

  - by user108264

  I am a new linux user so i am not familiar with what actually is needed to check. When shutting down or trying to restart i get a screen with yellow letters and the system does not close or restart. I have to shut down manually. I can't type all the numbers but i will give the last ones. [90102.232650] [ end-trace 435966f5b367871 ] this seems to have happened after i downgraded the xorg so i can get drivers for my ATI card(4850HD). The suspend command works fine.

• Keyboard activation bug

  - by Skydreamer

  I'm using Ubuntu's last version and there's still a little problem on my installation (already on previous versions). When I start the computer and reach the login screen, I have to wait about a minute to be able to begin to use my keyboard. That's not a real problem but that's kind of annoying. I've tried some things such as a lsusb via ssh and it worked and activated the keyboard without waiting. So I've tried to put it in the crontab (with @reboot) but it doesn't really work. Has someone got an idea how to solve this bug ? Thank you in advance.

• install 64 bit as dual boot with 32 bit

  - by profgeorgefhart

  I downloaded Ubuntu 12.10 - bit .iso onto a bootable USB and want to put it on to my 32 bit 12.10 system as a dual boot, using a totally separate 1 Tb disk [which already has data on it]. However, when I go to restart and hit F8 fir BIOS set-up, I can change all the settings except the boot search order. Is there some other way to force the startup to read the USB first? Is the fact that I cannot change the search order to do with the fact that the 32 bit OS was 'Installed in legacy mode' not 'EFI? How can I rectify this? (This might be related -- might I need to update my BIOS for my Intel DX38BT motherboard? I think their last upgrade was 2009.)

• PHP user created function return values problem

  - by faX

  Okay I'm new here and I have been trying to figure this out all day I have two functions one calling the other but my functions only returns the last value for example 29 when it should return multiple values.

• Massive crash and kernel panic after updates yesterday, what now?

  - by Ghost

  Got 12.04 on an AMD+radeon machine, everything was running fine until last night when the update manager installed new packages, and now the moment I open a browser (firefox, chromium, anything) it crashes instantly. It says warning: at build/buildd/linux-3.5.0/arch/x86/kernel/smp.c:123 native_smp_send_reschedule+0x5b/0x60() Pid: 2432, comm: chrome_dbthread tainted: G D 3.5.0-2generic #2-ubuntu I already tried uninstalling the packages from the update log, didn't solve a thing. Depending of which browser I use I get a different reaction, like a complete freeze instead of a text console crash. Ideas? I really don't know what to do.

• Need your opinion: which domain should I use for the blog?

  Reader new to my blog might have wondered why blog lives in a .NZ domain: to make a long story short is because when I started my blog I was soo excited about my relocation to New Zealand that I registered a .NZ domain. Then I came back to Italy, and started to work in Milano. Last autumn I had to chance to go back to New Zealand again, but at the same time the offer to work for an European Institution arrived. And then my .net.nz domain didn't make sense any more. And because it seems like I've...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

  Hello fellow developers, I am in my last year of Undergrad (Applied Math). I have discovered my passion for programming after taking a programming course (required by program), it was a basic Java course but I loved it! So I picked up an Apress C# Pro by Andrew Troelsen book. My degree is not in CompSci and I have under a year left to graduation. How do I prove myself as a programmer? What would you recommend I do in order to become hire-able?

• Restricted Flow Of Power

  - by user13827

  I'm sure all is fine, but i need some reassurance. Last month my company launched consolidated two of their websites into one new website. www.fdmgroup.com and www.fdmacademy.com into a newly designed www.fdmgroup.com. Because the FDM Academy grew as it's own brand we decided not to just forward the domain to the fdmgroup website, but instead just mirror the new FDM Group website and use a canonical tags to the FDM Group domain (so the link juice will pass to the FDM Group domain pages) The website has be live for nearly a month and i don't believe any power has passed down through the FDM Group website to it's deeper pages even though 301 redirects from the legacy group and academy domains in place. I am also seeing the same problem on the FDM Academy domain, but i expect to see this as every page has a canonical to the same page on the Is there anything which is restricting the flow of power through the site, or am i just being impatient. Thanks in advance Jon

• How can redirect pages from old core PHP site to new Joomla site?

  - by pkachhia

  We have our old site into core PHP and we have developed it again into Joomla 1.5 last year( because of some limitations we have to build it into 1.5). Now the problem is the URL of sites changed as we have use SEO URLS on joomla. In between we have use .htaccess to redirect user from old URL to new like this Redirect /pages/oldpage.php http://www.mydomain.com/products/category/new_page.html Is this good practice to redirect user to new URL or not?(we have used same server). One more thing, We have used splash page on our site, and to set up it we have made some changes and because of it one of the important link is not working, and it is http://www.mydomail.com/index.php How can I get rid of it? I have used DirectoryIndex splash.html home.html index.php in .htaccess to open splash page first when someone open my site http://www.mydomain.com. Note: my website hosted on dedicated ubuntu server.

• Whats New in RadMap for Silverlight / WPF in Q1 2010

  Now that the Q1 2010 release has passed I would like to bring to your attention the official release of one of our newest controls - RadMap for Silverlight [and WPF]. Most of you who are actively involved into the business of data visualization solutions probably are aware that with the Q3 2009 release last year we released a public beta (CTP) version of our map control and it naturally evolved into a fully-fledged control for our current official release. First of all – a BIG thanks to all of you early adopters, who gave the control a try and shared constructive feedback (and also lots of kind words ;)) with us and helped this to happen. So in the good tradition of my original overview of the CTP version of RadMap, I would like to highlight some of the most exciting new features that you might have missed in ...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

• What's a good model for continuous manager <-> programmer feedback?

  - by MebAlone

  Is it important for managers to give devs regular feedback on how they're doing and vice versa? I say vice versa because I consider employees to be responsible to their manager, and managers to be responsible to their employees. Everyone seems to think this is a good idea but in practice I rarely see it happen because so many shops are "agile" now and that usually means a daily standup plus a weekly kickoff, etc. So one-on-ones just don't happen. In my last position I had my first one-on-one w/ my manager 6 months after I'd been w/ the company. It turned out there was lots of misunderstanding, misalignment and confusion built up and snowballed. Not really surprising when there's no direct personal communication for that long.

• laptop screen goes blank after waking from sleep

  I have been facing this issue from the last week after some update. Whenever my laptop wakes up from suspend state it just shows me a blank screen. Regardless of whatever I do(move my mouse, press keyboard buttons) it just refuses to wake up. I am forced to do a restart and lose all my unsaved files. Has this issue been reported for Ubuntu 12.04? I am using a Lenovo X200 with Intel Mobile 4 Series Graphics Chipset. Please let me know if any body has found a fix for this.
