• SEO issue - External links rel="nofollow" or NOT!

  - by Mary Melody

  Previously I created a website for promo codes and coupons. That have hundreds of external links to the Retailer's websites and I used rel="nofollow" tag. But my site SEO rank was very very... bad especially on Google. So then I removed the rel="nofollow" tag, but no improvement. The only difference between this site and my other sites is "External links". My other sites have good ranking on Google. Now I'm creating a site for reviews. So this is also similar situation for me. I just want to know about how does SEO react with external links? and then what possibly happened in my case?

• 13.04 - Extenal monitor plugged on laptop HDMI shows image but lags a lot

  - by Thiago Fassina

  It uses an Nvidia GeForce GTS 250M. When I plug in the monitor, it shows some images but with bad FPS and lagging a lot. For example, when I move the mouse pointer, it leaves a trail that vanishes from time to time. I didn't install Nvidia drivers because every time I did this on past versions I ended up with an unbootable system. On past versions I just gave up trying to use the monitor cause it never showed anything regardless of what driver I installed. But since 13.04 ALMOST made it, I'll make another tries. ps.: Works perfectlty on Windows 7/8

• Adsense link units trageting better keywords?

  - by user1010609

  I have one link unit above my navigation which targets exact keywords on what my site is about, on contrary my adsense for content Leadbord and Wide Skyscraper show ads that are totally opposite from my keyword,while my ctr increased for about 10 times with link unit I noticed cpc is lower also (but that was just based on one day, today is higher). Is it so bad to completly get rid of standard content ads and put link units, because this way I earn so little for that site but I think that is because smart pricing (accidental clicks on ads that my users are not interested)? I earn in whole day with about 25-35 clicks as much as keyword tool shows for only one click,my site is first for the topic? I really don't know what to do.. Has anyone had similar situation or can give some advice?

• Tab navigation and double content

  - by Guisasso

  I have a website in which i use tabs to navigate between pages. For example, page a displays A as an active tab and B and C background tabs. If the visitor gets to the website via page B, i also would like to display to page d, but not a and c. Question: I know i can just create index2 for b for example, so when the visitor gets to b from a, i display a,b,c and index1 when visitor gets to b from d for example. Is that a bad practice? I know double content isn't good, but in which other way can i or should i approach this problem? The tab navigation i designed uses < li and id tag do display active tab, defined in the < body tag.

• Finding inspiration / help for making up (weapon) names

  - by Rookie

  I'm really bad with words, especially with English words. Currently I'm struggling to make a good weapon names for my game, it needs to display the weapon functionality (weak/strong/fast/ballistic etc) correctly as well. For example the best weapon in a (futuristic) game cannot be called just with the name "Laser", it's just too boring, right? Are there any tools, websites or anything that helps me finding good names for weapons? (or anything else similar). I was thinking to use scientific names, but noticed that they are really hard to write, and they get very long, and I also lack information about science, I only know I could use the atomic sub-particles names in the weapons for example. How do I get started with becoming good with making up names? (this could apply in generally to any naming problems).

• Is having 'Util' classes a cause for concern? [closed]

  - by Matt Fenwick

  I sometimes create 'Util' classes which primarily serve to hold methods and values that don't really seem to belong elsewhere. But every time I create one of these classes, I think "uh-oh, I'm gonna regret this later ...", because I read somewhere that it's bad. But on the other hand, there seem to be two compelling (at least for me) cases for them: implementation secrets that are used in multiple classes within a package providing useful functionality to augment a class, without cluttering its interface Am I on the way to destruction? What you say !! Should I refactor?

• Career Advice: masters degree or work experience [on hold]

  - by user95488

  I graduated about four years ago with a degree in mathematics and I currently work as a Software Developer/Business Analyst, but more Business Analyst. I've been working for about 4 years and and I am concerned with my long term career path. I would strongly prefer to do much more software development but to continue on my current path would lead me to an analyst role. I was thinking of getting a masters in computer science to help refocus my career toward core software development. Does anyone have any advice here? Is this a bad idea?

• How to optimize a one language website's SEO for foreign languages?

  - by moomoochoo

  DETAILS I have a website that's content is in English. It is a niche website with a global market. However I would like users to be able to find the website using their own language. The scenario I envision is that the searcher is looking for the English content, but is searching in their own language. An example could be someone looking for "downloadable English crosswords." MY IDEAS Buy ccTLDs and have them permanently redirect to subdirectories on domain.com. The subdirectories would contain html sitemaps in the target language e.g.-Redirect domain.fr to domain.com/fr OR perhaps it would be better to maintain domain.fr as an independent site in the target language with the html sitemap linking to pages on domain.com ? QUESTION Are the above methods good/bad? What are some other ways I can optimize SEO for foreign languages?

• After update, audio won't play throw hdmi cable

  - by ckhenderson

  Yesterday (June 7th) I faithfully updated a bunch of stuff through update manager (though I'm not sure what since I never read what I updated any more because I'm a bad person). Afterward, I discovered that I could no longer play audio through my tv via HDMI. The sound settings menu seems to have completely changed and the shell script that I wrote a week ago (with much pain and effort as I had never before written a shell script) to toggle between my laptop speakers and the HDMI cable output no longer works. When I type in pactl set-card-profile 0 output:hdmi-surround in the command line I get Failure: No such entity Presumably this means something with Pulse Audio changed but, while I'm learning a lot about the inner workings of Ubuntu/Linux, I'm not an expert and would love some help. EDIT: So I noticed that pacmd set-card-profile 0 output:hdmi-stereo seems to get everything working. Still, shouldn't there be a way to do this through the GUI as well?

• ssis 2012 timeouts

  Originally posted on: http://geekswithblogs.net/influent1/archive/2014/05/30/156699.aspxI started getting timeouts from SSIS 2012 using the SSISDB and I couldn't make any sense of them, they seemed random.  When things were bad I couldn't even expand the Integration Services Catalogs node in SSMS.  Just by sheer luck I figured out the problem: too much data was being logged in SSISDB and the data file was up to 180 GB, with the log file at 500 GB.  I switched it to simple mode and shrank the log file, then changed the retention period to 90 days instead of 365.  Now I need to see what else I can do to keep it running smoothly...Note this:  http://www.ssistalk.com/2012/07/16/ssis-2012-beware-the-ssis-server-maintenance-job/

• Is possible to write too many asserts?

  - by Lex Fridman

  I am a big fan of writing assert checks in C++ code as a way to catch cases during development that cannot possibly happen but do happen because of logic bugs in my program. This is a good practice in general. However, I've noticed that some functions I write (which are part of a complex class) have 5+ asserts which feels like it could potentially be a bad programming practice, in terms of readability and maintainability. I think it's still great, as each one requires me to think about pre- and post-conditions of functions and they really do help catch bugs. However, I just wanted to put this out there to ask if there is a better paradigms for catching logic errors in cases when a large number of checks is necessary.

• Testing Git competence

  - by David

  I hire a lot of programmers for tiny tasks. I very clearly specify that the tasks can only be completed by making a pull request on GitHub. Unfortunatelly, so many programmers do not know Git and often the programmers cannot complete the project due to not understanding/being willing to learn Git, even after they have undertaken the programming of the task. This is bad both for me and for the programmers. Sometimes I end up arguing for why it is inefficient that they just send me a zip file containing the code. Therefore, I am looking for an online service to certify that the programmers know how to make a pull request so I do not waste their nor my time. The certificate should be free for the coders, but may cost me. It is important that the course just focuses on exactly what is needed to make a clean pull request so it should not take more than 5 minutes to go through. Does such a thing exist?

• Is excessive indirection and/or redundant encapsulation a recognized concept?

  - by Omega

  I'm curious if there's a series of tendencies or anti-patterns when programming whereby a developer will always locally re-wrap external dependencies when consuming them. A slightly less vague example might be say when consuming an implementation of an interface or abstract, and mapping every touch-point locally before interacting with them. Like an overcomplicated take on composition. Given my example, would the interface not be reliable enough and any change to it never be surmountable any any level of indirection? Is this a good or a bad practice? Can it ever go too far? Does it have a proper name?

• Strategies for removing register_globals from a file

  - by Jonathan Rich

  I have a file (or rather, a list of about 100 files) in my website's repository that is still requiring the use of register_globals and other nastiness (like custom error reporting, etc) because the code is so bad, throws notices, and is 100% procedural with few subroutines. We want to move to PHP 5.4 (and eventually 5.5) this year, but can't until we can port these files over, clean them up, etc. The average file length is about 1000 lines. I've already cleaned up a few of the low-hanging fruit, however the job took almost an entire day for 2 300-500 line files. I am in a quagmire here (giggity). Anyway, has anyone else dealt with this in the past? Are there any strategies besides tracing backwards through the code? Most static analysis tools don't look at code outside of functions - are there any that will look at the procedural code and help find at least some of the problems?

• In C++, is it a reflection of poor software design if objects are deleted manually?

  - by grokus

  With the advent of smart pointers, is it a sign of poor design if I see objects are deleted? I'm seeing some software components in our product that people are still doing this. This practice strikes me as un-idiomatic, but I need to be sure this is the industry consensus. I'm not starting a crusade but it'd be nice to be prepared theory wise. Edit: legit uses of delete, Klaim mentioned the object pool use case. I agree. Bad examples of using delete, I am seeing many new's in constructor or start() and corresponding delete's in the destructor or stop(), why not use scoped_ptr? It makes the code cleaner.

• Quantal analyzes the HD in any boot

  - by Lucio

  I have installed Ubuntu 12.10 formating the HDD. Any time that I turn on the PC and boot Ubuntu, it always analyzes my HDD in search for bad blocks. This is what happens: When I turn on the PC and load Ubuntu, before I can login my user, appears the following image. If I press C, the process ends and I can work, if I wait until the process can finish by itself also I can work. Also I had this problem, related to the HDD. My Hard Disk Driver is a Western Digital. Is there any problem on the system? Can I stop this procedure? Information that can help: tune2fs -l output

• Boot Failure: No default or UI configuration directive found Normal install on laptop [closed]

  - by user79920

  I have had Ubuntu on my laptop for quite a while, it's just a standard install, no partitioning off, no wierdness of any other sort, just ubuntu. Today my computer started to lag really bad so I tried to restart it, but after bios loaded I just got an error that said "ERROR: No configuration file found No DEFAULT or UI configuration directive found!" After that it had "boot:" and a cursor, like it expects me to type something. Once again, this is just a normal install on my hard drive, not a VM or booting from USB. It's Ubuntu 12.04 on a Sony Vaio VGN-SZ240P Any help is appreciated!

• Mounting ddrescue image after recovery (in over my head)

• Trying to update Asus BIOS: FreeDOS crashes

  - by ZekeDroid

  My UX31 zenbook is experiencing some weird shutdown behavior when the battery drops below 50% and the internet seems to agree that updating the BIOS is a good step forward since there were issue with the kernel before. I downloaded both the correct BIOS file and the windows 7 utility tool and now need to boot FreeDOS to run, however, I've tried every method out there and they all fail (or so I think): Using unetbootin's FreeDOS 1.0 image I get to an error saying it couldn't run drivers then I get to a command line on disk A:. I assumed a dead end. Using unetbootin but with the FreeDOS 1.1 version image downloaded directly: get an error of "bad or missing command interpreter". I looked online and the solutions didn't work either. So, is there an alternative to FreeDOS or to installing a BIOS that I could use?

• Is premature optimization really the root of all evil?

  - by Craig Day

  A colleague of mine today committed a class called ThreadLocalFormat, which basically moved instances of Java Format classes into a thread local, since they are not thread safe and "relatively expensive" to create. I wrote a quick test and calculated that I could create 200,000 instances a second, asked him was he creating that many, to which he answered "nowhere near that many". He's a great programmer and everyone on the team is highly skilled so we have no problem understanding the resulting code, but it was clearly a case of optimizing where there is no real need. He backed the code out at my request. What do you think? Is this a case of "premature optimization" and how bad is it really?

• What is the term that means "keeping the arguments for different API calls as similar as possible"?

  - by larson4

  There is a word which I can never remember... it expresses a design goal that API calls (or functions or methods or whatever) should be as similar as reasonably possible in their argument patterns. It may also extend to naming as well. In other words, all other things being equal, it is probably bad to have these three functions: deleteUser(email) petRemove(petId,species) destroyPlanet(planetName,starName) if instead you could have deleteUser(userId) deletePet(petId) deletePlanet(planetId) What is the word for this concept? I keep thinking it's "orthogonal" but it definitely isn't. Its a very important concept, and to me it's one of the biggest things that makes some APIs a joy to work with (because once you learn a few things you can pretty much use everything without looking at doco), and others a pain (because every function is done inconsistently).

• How do you choose a programming/data structure/algorithm book?

  - by Fanatic23

  I really should not be mentioning the name of the book, but the first time I read it (during my under-grad days) I almost concluded that data structure was a bad course to pick. Which brings me to the question I am asking here. What makes a programming or data structure or algorithm book tick? Clearly, lucid explanation is one. But I also realize that organization of the material is very important and so is diagrams. What else? Some pointers would obviously help when I hang out in my neighborhood computer book shop the next time.
