  • USB 3.0 controller is not recognized

    - by BlueWanderer
    I have a Thinkpad E430 notebook, and the intel's USB 3.0 controller can not be recognized by Ubuntu 12.04. The LED on my USB-HDD is white instead of blue (And in Windows 7, it is blue when connected to USB 3.0 port, and is white when connected to 2.0). And the transfer speed is around 25MB/s instead of 65MB/s in Windows 7. I'm not familiar with Linux systems, so I've no clue about what's going wrong. I've searched the web, but got no solution.

  • Agile team with no dedicated Tester members. Insane or efficient?

    - by MetaFight
    I'm a software developer. I've been thinking a lot about the efficiency of the Software Testers I've worked with so far in my career. In fact, I've been thinking a lot about the Software Testers role in general and have reached a potentially contentious conclusion: Non-developer Software Testers staff are less efficient at software testing than developers. Now, before everyone gets upset, hear me out. This isn't mere opinion: Software Testing and Software Development both require a lot of skills in common: Problem solving Thinking about corner cases Analytical skills The ability to define clear and concise step-by-step scenarios What developers have in addition to this is the ability to automate their tests. Yes, I know non-dev testers can automate their tests too, but that often then becomes a test maintenance issue. Because automating UI tests is essentially programming, non-dev members encounter all the same difficulties software developers encounter: Copy-pasta, lack of code reusibility/maintainability, etc. So, I was wondering. Why not replace all non-dev roles with developer roles? Developers have the skills required to perform Software Testing tasks, and they have the skills to automate tests and keep them maintainable. Would the following work: Hire a bunch of developers and split them into 2 roles: Software developers Software developers doing testing (some manual, mostly automated by writing integration tests, unit tests, etc) Software developers doing application support. (I've removed this as it is probably a separate question altogether) And, in our case since we're doing Agile development, rotate the roles every sprint or two. Also, if at all possible, try to have people spend their Developer stints and Testing stints on different projects. Ideally you would want to reduce the turnover rate per rotation. So maybe you could have 2 groups and make sure the rotation cycles of the groups are elided. So, for example, if each rotation was two sprints long, the two groups would have their rotations 1 sprint apart. That way there's only a 50% turn-over rate per sprint. Am I crazy, or could this work? (Obviously a key component to this working is that all devs want to be in the 3 roles. Let's assume I'm starting a new company and I can hire these ideal people) Edit I've removed the phrase "QA", as apparently we are using it incorrectly where I work.

  • How to Obtain the Best SEO Services

    The present IT field is full of companies that boast of offering best SEO services at an affordable rate. Some even notify that they provide cost effective SEO services without compromising on the quality. Though a majority of the websites try to negotiate on the price, the services are still worth to obtain by paying the quoted price. The aspect of choosing SEO services that provide best quality is an uphill task. One of the factors that favour this aspect is thorough research on the Internet.

  • SEO is Not All About Link Building, It's About Execution

    The most people hear the term "SEO", it is generally heavily associated with link building, and dominating in the search engines. Truth be told, whilst this still remains a large part of what it is that you do to rank, it is not the be all and end all. In fact, the most important aspect of SEO is in how you execute it, and this is why the success rate of those who learn methods is actually quite low. Let me demonstrate.

  • SEO Content to Deliver Value to Your Customers

    When most people talk about SEO content they refer to stuff that is written merely to please the search engines but when the readers go through it, they find nothing but a whole lot of crap. With such content you might be able to get visitors to your site however it will be very difficult to keep them on the site for long because once they read the badly organized content they'll go away. This would mean that you conversion rate would be pretty low, which ultimately signals that you are not making enough of sales.

  • SEO - What is That? - Why You Need to Do It!

    In this article I try to explain the differences between Internet Marketing and SEO or Search Engine Optimization in a simple form so it is easily understood. I think the importance of SEO is quite often overlooked for the easier and much emphasized way of marketing and that is email and lead generation marketing using a sequence of letters and auto responders. There is such a high failure rate in marketing today and I think part of that could be related to the form of marketing one is relying on.

  • Primary IDE Channel: Ultra DMA Mode 5 >> PIO Mode

    - by Wesley
    Hi, my netbook was having huge audio lag and just abnormally slow processing. After doing some searching on the internet, I found out that I needed to uninstall/reinstall the Primary IDE Channel found under the IDE controller section in the Device Manager. I would then set the Transfer Mode to DMA if available and everything would be great. For a period of time, I would see that "Ultra DMA Mode 5" was the current transfer mode, but every so often, it'd revert back to "PIO Mode", which is when it's really laggy. What can I do to prevent the Primary IDE Channel to revert from Ultra DMA Mode to PIO Mode? Also, my netbook has BSODed a few times when it is in PIO Mode, without any real explanation. I have a Samsung N120. Specs are as follows: http://www.samsung.com/ca/consumer/office/mobile-computing/netbook/NP-N120-KA01CA/index.idx?pagetype=prd_detail&tab=spec&fullspec=F. Only difference is that I have upgraded to 2.0 GB of DDR2 RAM. EDIT: For all who are looking for an answer to this problem, click the link in Kythos's answer and look at number 6 (Re-enable DMA using the Registry Editor). This always works for me now. If on reboot, you seem to only have a black screen after XP is loading, just wait... it is still loading and will show signs of life after 2-3 minutes.

  • How can I capture output from LFTP? (Output not written to STDOUT or STDERR?)

    - by jondahl
    I would like get access to progress information from lftp. Currently, I'm using curl like so: curl http://example.com/file -o file -L 2> download.log This writes curl's progress information to the download.log file, which I can tail to get real-time progress. But the same approach doesn't work with lftp, either with stdout or stderr. I end up with an empty download.log file, until the transfer is complete. lftp -e 'get http://example.com/file;quit' 2> download.log lftp -e 'get http://example.com/file;quit' 1> download.log When I don't redirect output, I see progress on the screen. When I do redirect output, I stop seeing progress on the screen, but nothing shows up in download.log. After the file transfer is complete, I see the final result, like this - but nothing before: 97618627 bytes transferred in 104 seconds (913.1K/s) Is lftp doing something unusual with its output - printing to screen without printing to stdout/stderr? Are there other ways of capturing screen output than redirecting stdout/stderr?

  • How can I forward an application with X11 in grayscale

    - by ??????? ???????????
    I am trying to run a graphical application at home and display it on a it on a laptop which is located about six routing hops away. The problem is that the connection is so slow (or rather there is so much GOOEY being transfered) that the mouse is unresponsive and it takes a "long time" to redraw the window even at a resolution of 800x600 pixels. The connection speeds are 10MBit up at home and about 1MBit down on the laptop, which I think should be sufficient for looking at some GUI in (almost) real time. Since this traffic is sent over over a secure shell, I have enabled Compression with highest CompressionLevel along with Ciphers set to blowfish-cbc. This has substantially improved the responsiveness of the application, making it nearly usable. However, my goal is to improve the performance even further by sacrificing colors and even frame rate. The application to be displayed a Qemu SDL window with a graphically-oriented OS in it. This is not strictly relevant, but perhaps there are options to tweak the SDL output which I am not aware of. A possible workaround would be to run the application in a "hidden" X server and enabling TigerVNC on that X server. This would automatically give me the benefits of an optimized VNC viewport, but the goal is to do without (reduce complexity). The question I'm asking is what are my options for reducing the data-rate generated on the server in order to make the graphical application more usable on the client. As mentioned, colors are not important and I could probably work with 5-16 fps. Both machines are running Gentoo with the software in question being: workstation X.Org X Server 1.10.4 OpenSSH_5.8p1-hpn13v10, OpenSSL 1.0.0e QEMU emulator version 0.15.1 (qemu-kvm-0.15.1) laptop X.Org X Server 1.12.2 OpenSSH_5.8p1-hpn13v10lpk, OpenSSL 1.0.0j

  • EC2 Ubuntu - Force instance to use internal IP

    - by Peter
    I've just set up a micro instance on EC2 (AMI ID ami-e59ca991). I had hoped to avoid charges for a year as my usage falls well within the bound of the free tier. I have been charged $0.01 for "regional data transfer". I read here that this is because my instance is talking to its self via it's external IP address. From what I've Googled it looks like you can stop the charges by making sure that the instance uses its internal IP address. However, when I ping the hostname of my instance internally (via an ssh session) it resolves to the instances internal IP address. How can I configure my instance so that I do not get these charges? Is it as simple as adding a line to my hosts file? Additionally, is this the real reason for the charge? I'm concerned that I've misunderstood the pricing somewhere. I have Apace and MySQL (with phpmyadmin) running on the machine - could I be being charged for data transfer associated with these (I have only one flat HTML page and I have only logged in via phpmyadmin - I have no data in my database). Edit: Additionally, my user account on MySQL was declared as: grant all privileges on *.* to 'peter'@'localhost'; Should I have instead used the internal hostname for the instance? grant all privileges on *.* to '[email protected]'; Cheers, Pete

  • Why do (Russian) characters in some received emails change when reading in David InfoCenter?

    - by waszkiewicz
    I'm using David InfoCenter as email Software, and I have troubles with some of my emails in Russian. It's only a few letters, in some emails (sent from different people), like for example the "R" ("P" in russian) will be shown as a "T". In other emails in Russian, the problem doesn't appear. Isn't it strange? Does anyone had the same problem already and found where it came from? When I transmit that email to an external mailbox (internet email account), it's even worse, and gives me symbols instead of all Russian letters... The default encoding was "Russian (ISO)", I changed it to "Russian (Windows)", but same problem. Another weird reaction is when I write an intern email and name it TEST in Russian (????), with ???? in the text window, it changes the title to "Oano"? But the content stays in Russian... With Mailinator I got the following, for message and subject "????": Subject: ????

  • Ingress filtering in Linux traffic control: Redirect traffic to IFB device

    I have an openwrt router and I want to shape incoming traffic in order to classify all the traffic addressed to a certain IP address in my home network as low priority.

  • File recovery from Mac results in random files and extensions – how do I get my data back?

    - by Robsta
    This Mac hard drive was dying. Someone I knew did a file recovery and got as many files as he could. The program (not sure how it was done, or what program it was) dished out a bunch of folders names such as: DIR56.TOC DIR55.CUR DIR54.GPZ DIR53.GZI … and so forth, all the way down to DIR0.LZH. Some of the file extensions I do understand — like .JPEG, or .MOV — but most of them are ones I've never heard of. I've googled some of them like .TOC, wich stands for "table of contents", but I don't understand how to transfer that data back to the Mac. Currently, they are on a Windows machine. They are being transfered onto an external hard drive that the Mac can read. It can also see all the files. However, the few that I tested to see if the Mac recognizes them (like .TOC and .CUR) cannot be opened. Anyone have any idea as to what I should do? There are some important assignments on there I need to get. EDIT: Data transfer was most likely done by: Easy Recover 6 professional (95% sure, no guarantee)

  • How much network latency is "typical" for east - west coast USA?

    - by Jeff Atwood
    At the moment we're trying to decide whether to move our datacenter from the west coast (Corvallis, OR) to the east coast (NY, NY). However, I am seeing some disturbing latency numbers from my location (Berkeley, CA) to the NYC host. Here's a sample result, retrieving a small .png logo file in Google Chrome and using the dev tools to see how long the request takes: Berkeley to NYC server: 215 ms latency, 46ms transfer time, 261ms total Berkeley to Corvallis server: 114ms latency, 41ms transfer time, 155ms total some URLs if you want to try yourself: http://careers.stackoverflow.com/content/cso/img/logo.png (NY, NY) http://serverfault.com/cache/logo.png (Corvallis, OR) It makes sense that Corvallis, OR is geographically closer to Berkeley, CA so I expect the connection to be a bit faster.. but I'm seeing an increase in latency of +100ms when I perform the same test to the NYC server. That seems .. excessive to me. Particularly since the time spent transferring the actual data only went up 10%, yet the latency went up ten times as much! That feels... wrong... to me. I found a few links here that were helpful (through Google no less!) ... http://serverfault.com/questions/63531/does-routing-distance-affect-performance-significantly http://serverfault.com/questions/61719/how-does-geography-affect-network-latency http://serverfault.com/questions/6210/latency-in-internet-connections-from-europe-to-usa ... but nothing authoritative. So, is this normal? It doesn't feel normal. What is the "typical" latency I should expect when moving network packets from the east coast <--> west coast of the USA?
