  • Off-Page SEO - The Ethos of Backlinking

    I want to delve under the bonnet more regarding off-page, so let's get to it! How do we get backlinks to our site? It may seem easy and what springs to mind for many is to ask someone to link to your site while in return you link back to theirs. In general this is a very fair and sensible undertaking, it really is. However, in Google's eyes and perhaps in the other two big search engines too now, its not counted as a valuable link any longer.

  • How can I figure out if programming is right for me? [closed]

    - by user66414
    I have an IT background and was pretty confident until an opportunity came up at work to go into programming(C#). I have never programmed before this, and the software I am programming for is a program I have never used before (a 3D modeling software). It has been 6 months since then and I feel like giving up. I didn't get much training... about 3 weeks of training spread out over the last 6 months. I think I would be good at programming but this experience is kinda making me rethink my decision. I'm not sure if it's just me, or if this frustration is normal. How can I tell if programming is right for me?

  • Poll: What kind of computer should a corporate provide to their developers.

      I have been collecting a poll to almost any developer I find on my way as well as business owners. I have been looking to see what a small development shop, medium size company and a big corporate considers when providing development computers to their software developers. This has being very intriguing to me. In my career I found different software developers, the ones that work always with one product and one framework, as well as the one that keeps a few frameworks and projects. Of course...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight.

  • How can I use LightDM for user-defined sessions?

    - by Philipp
    If I unterstand it correctly, LightDM has replaced GDM per default. I wonder if it's possible to make it run the things I put in my .xinitrc file ... what I need is an option below "Unity" and "Unity 2D" which says "Run a user-defined session". Is that possible? Should be the easiest thing, but I did not get a clue so far. I export and define and run a lot of things in this file, so it's pretty important for me to have control over that. What I do NOT want is a custom session in /usr/some/where, I only want it to run the stuff from each user's xinitrc (or similar).

  • Designing a hierarchical structure with lots of reads and writes?

    - by JD01
    I am in the process of working on a video on demand system part of it involves the management of a hierarchical tree structure (think windows explorer) which allows users to upload videos, move folders around, create new folders etc. User action will be allowed depending on which permissions they have. In addition to managing the structure (creating folders and uploading videos), subscribers will be viewing content (read access). The number of reads will be significantly more than the writes. My question (and it is big one) is should I store the data in a database (for the writes) and also have some sort of cache which will be used for the reads? or do I use two databases? or is there a better solution? Also I will have to resolve concurrency issues which I think optimistic locking on the database will resolve. I have a fair bit about CQRS over the last few months but not sure if this is the way to go. Any ideas?

  • for vs. foreach vs. LINQ

    - by beccoblu
    When I write code in Visual Studio, ReSharper (God bless it!) often suggests me to change my old-school for loop in the more compact foreach form. And often, when I accept this change, ReSharper goes a step forward, and suggests me to change it again, in a shiny LINQ form. So, I wonder: are there some real advantages, in these improvements? In pretty simple code execution, I cannot see any speed boost (obviously), but I can see the code becoming less and less readable... So I wonder: is it worth it?

  • appearance incomplete

    - by user288986
    I'm using 14:04 which is pretty nice. Something wionders me: if I open a window (e.g. Ubuntu Software Centre) I can see SOME items (sometimes nothing) but by hovering the mouse over it it appears - and then disappears again. Sometimes the side mover acts the same way... Maybe it has to do with my hardware: P4, 3 GHz, 2 GB RAM, older graphics board, KVM-switch? There's no difference whether I use Gnome, Ubuntu standard, Ubuntu classic, Ubuntu fallback... Thanks for hints Jens

  • Version Not Final, Does not represent actual game footage?

    - by thinly veiled question mark
    Just curious about this. Frequently, a lot of gameplay videos from big studios have small subtitled text at the lower part of the screen, reading something like: Pre-Alpha Gameplay -- Footage not Final Game Footage not Final Pre-Alpha, Game here is not final Is there some sort of reason they do this? Is there some sort of legal ramification that they need to go through by adding this? I have especially seen some gameplay vids whose titles are "Alpha x.x.x", yet still, in the video itself, it always something like "footage not final, game may change".

  • Goings On

    The last several weeks have been pretty hectic for me. First, Visual Studio 2010 and .NET Framework 4 shipped. Of course, only those living in caves and under rocks missed that bit of news. However, that event forced me to leave my own cave and make a few public appearances.

  • How can I show contextual ads after a user filtered page contents by keyword?

    - by lex82
    I am building a social bookmarking service that is monetized in part by Google Adsense. However, I don't know how to influence how the ads are displayed. I think Google scans my pages and decides itself which ads to show where. Navigation on my site is mainly based on the selection of categories or tags being provided by the users. So after a user filters a list of bookmarks by the tag "SEO", I think I know pretty well what he is looking for. So I am looking for a service that allows me to show contextual ads for these particular keywords. How I can guide Google to show relevant ads? Can you recommend an alternative ad network, that gives me more control?

  • SimpleViewer + lightbox

    - by singles
    Is it possible to integrate any kind of Lightbox with SimpleViewer? But I don't want to display SimpleViewer in Lightbox. I want to Lightbox show when I click on one of the images in SimpleViewer. Does anyone tried that with success? EDIT I have a SimpleViewer page now. I just want to bind handler to clicking an image (as normally in HTML based pages), fetch big image url and show that image (not SimpleViewer!) in Ligthbox/ThickBox/FancyBox etc.

  • What does the SEO market look like? [closed]

    - by TheEconomist
    I'm an economist (aspiring economist, if we are being technical) and my curiousity has been recently piqued by search engine optimization services. I had the following questions. 1) What industries most widely use search engine optimization services? 2) Is it small business or big firms that use SEO services typically? 3) What is SEO pricing typically dependent upon and how much is it on average? 4) Do SEO services really increase traffic? Is there a dataset I can get a hold of for this sort of thing? I am not looking for answers to the questions necessarily. Although answers would help, a nudge in the right direction is more than sufficient, and greatly appreciated. Thank you!

  • Ubuntu 14.04 is unstable on my Thinkpad T61

    - by user292386
    I have this super old Thinkpad T61 and installed Ubuntu 14.04 on it. I noticed X11 is quite unstable. It'd freeze all the time, especially after suspension. Sometimes dash would appear as a blue screen, etc, etc. I have tried Xunbuntu as well. It's pretty much the same. But I don't seem to have problem with Debian 7.5. I still prefer Ubuntu to Debian. I just wonder which build of Ubuntu would have similar video/X versions as Debian 7.5. Thanks.

  • Managing shots of the player

    - by Bitbridge
    I'm currently developing a 2D Jump'n'Run and the situation is the following: The player has different weapons he can collect and is then able to shoot the weapon's projectiles (laser, rockets, whatever). In my previous game (space shooter) I just had a manager class for all the weapon-shots, it stored them in a container and then updates and draws every single one. When the "shoot-event" occurred, the "ProjectileManager" was notified and it added the wanted projectile. The input for player action is handled in the player-class, so the player would have to know the manager to call the function of the manager. I also have a collisionManager, that checks for collisions between, for example, enemies and the projectiles and then notifies these objects. However, I somehow have the feeling, that I shouldn't use this approach and that there might be a better way to handle this. I know, the question is a bit vague, I'm pretty much just looking for input and ideas to improve my design.

  • How to hide assets from user? ( e.g.: a png file )

    - by burninggramma
    I think the title is quite self-explaining, still this is a big area I think, so let me drop a few words: I've got a simple experiment game project going, and I want to make sure, that the user isn't messing with the game assets like player skin etc. In my opinion the best way would be that on production I would merge all the assets into one file and the application would check the hash of that file, so it could detect the corrupted data. Is this an acceptable practice? There must be sum libraries / applications which are targeting this problem, could you guide me on this? Project details: unix/linux, c++, sdl

  • Organize a game set

    - by jncunha
    I'm developing a endless running game and I'm not really sure on how to make the set. The first approach was to make a BIG set like 10240x3072 pixels so that we have a nice portion of set. After having like 3 or 4 sets that go along with each other I would work on making their elements sequential and repeatable. However this is getting really heavy for the iPad 1 (it's running good in the iPad 2 and the New iPad) even though I'm splitting all the set in slices through Photoshop. For the implementation I'm using Cocos2D. Is there any better approach to make something like this but truly efficient for the iPad memory? Thank you.

  • Recommended Books for OpenGL [closed]

    - by TheBlueCat
    I'm fairly new to OpenGL and I'm have been researching any books that would be beneficial, I've had suggested to me (I've finished reading the OpenGL Book online): Real Time Rendering GPU Gems 3 OpenGL Super Bible Does anyone know any other books that they've found useful in the past, even if it covers higher level algorithms. Also, can anyone suggest an IDE/Text Editor for Linux? I'm using Komodo and it's super buggy, I just booted into Windows today and tried Visual Studio and loved it, is their anything similar for Linux? Although, the books I've been reading are saying to not use IDEs, partly because of the reliance you place onto them, per se. I use Eclipse a lot for my Java programming, can I use C and OpenGL with that? Lastly, do you think it would be more beneficial staying on Windows and programming in C/OpenGL on their, I do like Linux, but I found Visual Studio to be pretty good in some aspects?

  • Nvidia tearing, any progress?

    - by Taerus
    I've been having tearing issues with Nvidia drivers since i installed ubuntu. I've tried every driver, from ubuntu ppa to xorg-edgers etc. None seem to relieve me of this burden. The only way for me (luckily this is my laptop) is to switch over to my intel graphics which is pretty reasonable. However as i've been searching, i noticed how many articles on this matter are at least from half a year to sometimes even three years ago. So i was wondering if there has been made any progress on this matter. Currently i'm using a GTX765M.

  • client problems - misaligned expectations & not following SDLC protocols

    - by louism
    hi guys, im having some serious problems with a client on a project - i could use some advice please the short version i have been working with this client now for almost 6 months without any problems (a classified website project in the range of 500 hours) over the last few days things have drastically deteriorated to the point where ive had to place the project on-hold whilst i work-out what to do (this has pissed the client off even more) to be simplistic, the root cause of the issue is this: the client doesnt read the specs i make for him, i code the feature, he than wants to change things, i tell him its not to the agreed spec and that that change will have to be postponed and possibly charged for, he gets upset and rants saying 'hes paid for the feature' and im not keeping to the agreement (<- misalignment of expectations) i think the root cause of the root cause is my clients failure to take my SDLC protocols seriously. i have a bug tracking system in place which he practically refuses to use (he still emails me bugs), he doesnt seem to care to much for the protocols i use for dealing with scope creep and change control the whole situation came to a head recently where he 'cracked it' (an aussie term for being fed-up). the more terms like 'postponed for post-launch implementation', 'costed feature addition', and 'not to agreed spec' i kept using, the worse it got finally, he began to bully me - basically insisting i shut-up and do the work im being paid for. i wrote a long-winded email explaining how wrong he was on all these different points, and explaining what all the SDLC protocols do to protect the success of the project. than i deleted that email and wrote a new one in the new email, i suggested as a solution i write up a list of grievances we both had. we than review the list and compromise on different points: he gets some things he wants, i get some things i want. sometimes youve got to give ground to get ground his response to this suggestion was flat-out refusal, and a restatement that i should just get on with the work ive been paid to do so there you have the very subjective short version. if you have the time and inclination, the long version may be a little less bias as it has the email communiques between me and my client the long version (with background) the long version works by me showing you the email communiques which lead to the situation coming to a head. so here it is, judge for yourself where the trouble started... 1. client asked me why something was missing from a feature i just uploaded, my response was to show him what was in the spec: it basically said the item he was looking for was never going to be included 2. [clients response...] Memo Louis, We are following your own title fields and keeping a consistent layout. Why the big fuss about not adding "Part". It simply replaces "model" and is consistent with your current title fields. 3. [my response...] hi [client], the 'part' field appeared to me as a redundancy / mistake. i requested clarification but never received any in a timely manner (about 2 weeks ago) the specification for this feature also indicated it wasnt going to be included: RE: "Why the big fuss about not adding "Part" " it may not appear so, but it would actually be a lot of work for me to now add a 'Part' field it could take me up to 15-20 minutes to properly explain why its such a big undertaking to do this, but i would prefer to use that time instead to work on completing your v1.1 features as a simplistic explanation - it connects to the change in paradigm from a 'generic classified ad' model to a 'specific attributes for specific categories' model basically, i am saying it is a big fuss, but i understand that it doesnt look that way - after all, it is just one ity-bitty field :) if you require a fuller explanation, please let me know and i will commit the time needed to write that out also, if you recall when we first started on the project, i said that with the effort/time required for features, you would likely not know off the top of your head. you may think something is really complex, but in reality its quite simple, you might think something is easy - but it could actually be a massive trauma to code (which is the case here with the 'Part' field). if you also recalled, i said the best course of action is to just ask, and i would let you know on a case-by-case basis 4. [email from me to client...] hi [client], the online catalogue page is now up live (see my email from a few days ago for information on how it works) note: the window of opportunity for input/revisions on what data the catalogue stores has now closed (as i have put the code up live now) RE: the UI/layout of the online catalogue page you may still do visual/ui tweaks to the page at the moment (this window for input/revisions will close in a couple of days time) 5. [email from client to me...] *(note: i had put up the feature & asked the client to review it, never heard back from them for a few days)* Memo Louis, Here you go again. CLOSED without a word of input from the customer. I don't think so. I will reply tomorrow regarding the content and functionality we require from this feature. 5. [from me to client...] hi [client]: RE: from my understanding, you are saying that the mini-sale yard control would change itself based on the fact someone was viewing for parts & accessories <- is that correct? this change is outside the scope of the v1.1 mini-spec and therefore will need to wait 'til post launch for costing/implementation 6. [email from client to me...] Memo Louis, Following your v1.1 mini-spec and all your time paid in full for the work selected. We need to make the situation clear. There will be no further items held for post-launch. Do not expect us to pay for any further items other than those we have agreed upon. You have undertaken to complete the Parts and accessories feature as follows. Obviously, as part of this process the "mini search" will be effected, and will require "adaption to make sense". 7. [email from me to client...] hi [client], RE: "There will be no further items held for post-launch. Do not expect us to pay for any further items other than those we have agreed upon." a few points to consider: 1) the specification for the 'parts & accessories' feature was as follows: (i.e. [what] "...we have agreed upon.") 2) you have received the 'parts & accessories' feature free of charge (you have paid $0 for it). ive spent two days coding that feature as a gesture of good will i would request that you please consider these two facts carefully and sincerely 8. [email from client to me...] Memo Louis, I don't see how you are giving us anything for free. From your original fee proposal you have deleted more than 30 hours of included features. Your title "shelved features". Further you have charged us twice by adding back into the site, at an addition cost, some of those "shelved features" features. See v1.1 mini-spec. Did include in your original fee proposal a change request budget but then charge without discussion items included in v1.1 mini-spec. Included a further Features test plan for a regression test, a fee of 10 hours that would not have been required if the "shelved features" were not left out of the agreed fee proposal. I have made every attempt to satisfy your your uneven business sense by offering you everything your heart desired, in the v1.1 mini-spec, to be left once again with your attitude of "its too hard, lets leave it for post launch". I am no longer accepting anything less than what we have contracted you to do. That is clearly defined in v1.1 mini-spec, and you are paid in advance for delivering those items as an acceptable function. a few notes about the above email... i had to cull features from the original spec because it didnt fit into the budget. i explained this to the client at the start of the project (he wanted more features than he had budget hours to do them all) nothing has been charged for twice, i didnt charge the client for culled features. im charging him to now do those culled features the draft version of the project schedule included a change request budget of 10 hours, but i had to remove that to meet the budget (the client may not have been aware of this to be fair to them) what the client refers to as my attitude of 'too hard/leave it for post-launch', i called a change request protocol and a method for keeping scope creep under control 9. [email from me to client...] hi [client], RE: "...all your grievances..." i had originally written out a long email response; it was fantastic, it had all these great points of how 'you were wrong' and 'i was right', you would of loved it (and by 'loved it', i mean it would of just infuriated you more) so, i decided to deleted it start over, for two reasons: 1) a long email is being disrespectful of your time (youre a busy businessman with things to do) 2) whos wrong or right gets us no closer to fixing the problems we are experiencing what i propose is this... i prepare a bullet point list of your grievances and my grievances (yes, im unhappy too about how things are going - and it has little to do with money) i submit this list to you for you to add to as necessary we then both take a good hard look at this list, and we decide which areas we are willing to give ground on as an example, the list may look something like this: "louis, you keep taking away features you said you would do" [your grievance 2] [your grievance 3] [your grievance ...] "[client], i feel you dont properly read the specs i prepare for you..." [my grievance 2] [my grievance 3] [my grievance ...] if you are willing to give this a try, let me know will it work? who knows. but if it doesnt, we can always go back to arguing some more :) obviously, this will only work if you are willing to give it a genuine try, and you can accept that you may have to 'give some ground to get some ground' what do you think? 10. [email from client to me ...] Memo Louis, Instead of wasting your time listing grievances, I would prefer you complete the items in v1.1 mini-spec, to a satisfactory conclusion. We almost had the website ready for launch until you brought the v1.1 mini-spec into the frame. Obviously I expected you could complete the v1.1 mini-spec in a two-week time frame as you indicated and give the site a more profession presentation. Most of the problems have been caused by you not following our instructions, but deciding to do what you feel like at the time. And then arguing with us how the missing information is not necessary. For instance "Parts and Accessories". Why on earth would you leave out the parts heading, when it ties-in with the fields you have already developed. It replaces "model" and is just as important in the context of information that appears in the "Details" panel. We are at a stage where the the v1.1 mini-spec needs to be completed without further time wasting and the site is complete (subject to all features working). We are on standby at this end to do just that. Let me know when you are back, working on the site and we will process and complete each v1.1 mini-spec, item by item, until the job is complete. 11. [last email from me to client...] hi [client], based on this reply, and your demonstrated unwillingness to compromise/give any ground on issues at hand, i have decided to place your project on-hold for the moment i will be considering further options on how to over-come our challenges over the next few days i will contact you by monday 17/may to discuss any new options i have come up with, and if i believe it is appropriate to restart work on your project at that point or not told you it was long... what do you think?
