• How do you support your code post employment end?

  - by James

  What is the process for leaving a company (or even a group/division) in terms of code support? Is it best to handle all questions? Do you give the remaining developers access to yourself as a future resource? If so, is there a way to not give full access? I've experienced first hand where answers about the general software arthitecture from the initial developer would be invaluable. I understand that if serious assistance is needed, than it becomes a typical case of employment negotiation as a support contract. However, should serious assistance be required, what steps can you make to ease that process of contacting you? I was thinking of doing something like making a (YOUR_NAME)_codesupport @ (YOUR_FAVORITE_EMAIL_CLIENT).com address. My Situation Specifics: I'm a co-op student, and as such bounce around companies on 4-month stints. This means introducing myself to a lot of new code bases, as well as leaving a fair share of orphaned code behind when I leave a company. I feel bad if I leave junk code around.

• Skynet Big Data Demo Using Hexbug Spider Robot, Raspberry Pi, and Java SE Embedded (Part 3)

  - by hinkmond

  In Part 2, I described what connections you need to make for this demo using a Hexbug Spider Robot, a Raspberry Pi, and Java SE Embedded for programming. Here are some photos of me doing the soldering. Software engineers should not be afraid of a little soldering work. It's all good. See: Skynet Big Data Demo (Part 2) One thing to watch out for when you open the remote is that there may be some glue covering the contact points. Make sure to use an Exacto knife or small screwdriver to scrape away any glue or non-conductive material covering each place where you need to solder. And after you are done with your soldering and you gave the solder enough time to cool, make sure all your connections are marked so that you know which wire goes where. Give each wire a very light tug to make sure it is soldered correctly and is making good contact. There are lots of videos on the Web to help you if this is your first time soldering. Check out Laday Ada's (from adafruit.com) links on how to solder if you need some additional help: http://www.ladyada.net/learn/soldering/thm.html If everything looks good, zip everything back up and meet back here for how to connect these wires to your Raspberry Pi. That will be it for the hardware part of this project. See, that wasn't so bad. Hinkmond

• Java's Object.wait method with nanoseconds: Is this a joke or am I missing something

  - by Krumia

  I was checking out the Java API source code (Java 8) just out of curiosity. And I found this in java/lang/Object.java. There are three methods named wait: public final native void wait(long timeout): This is the core of all wait methods, which has a native implementation. public final void wait(): Just calls wait(0). And then there is public final void wait(long timeout, int nanos). The JavaDoc for the particular method tells me that, This method is similar to the wait method of one argument, but it allows finer control over the amount of time to wait for a notification before giving up. The amount of real time, measured in nanoseconds, is given by: 1000000*timeout+nanos But this is how the methods achieves "finer control over the amount of time to wait": if (nanos >= 500000 || (nanos != 0 && timeout == 0)) { timeout++; } wait(timeout); So this method basically does a crude rounding up of nanoseconds to milliseconds. Not to mention that anything below 500000ns/0.5ms will be ignored. Is this piece of code bad/unnecessary code, or am I missing some unseen virtue of declaring this method, and it's no argument cousin as the way they are?

• What's wrong with cplusplus.com?

  - by Kerrek SB

  This is perhaps not a perfectly suitable forum for this question, but let me give it a shot, at the risk of being moved away. There are several references for the C++ standard library, including the invaluable ISO standard, MSDN, IBM, cppreference, and cplusplus. Personally, when writing C++ I need a reference that has quick random access, short load times and usage examples, and I've been finding cplusplus.com pretty useful. However, I've been hearing negative opinions about that website frequently here on SO, so I would like to get specific: What are the errors, misconceptions or bad pieces of advice given by cplusplus.com? What are the risks of using it to make coding decisions? Let me add this point: I want to be able to answer questions here on SO with accurate quotes of the standard, and thus I would like to post immediately-usable links, and cplusplus.com would have been my choice site were it not for this issue. Update: There have been many great responses, and I have seriously changed my view on cplusplus.com. I'd like to list a few choice results here; feel free to suggest more (and keep posting answers). As of June 29, 2011: Incorrect description of some algorithms (e.g. remove). Information about the behaviour of functions is sometimes incorrect (atoi), fails to mention special cases (strncpy), or omits vital information (iterator invalidation). Examples contain deprecated code (#include style). Inexact terminology is doing a disservice to learners and the general community ("STL", "compiler" vs "toolchain"). Incorrect and misleading description of the typeid keyword.

• Planning milestones and time

  - by Ignas

  I was hired by a marketing company a year ago initially for link building / SEO stuff, but I'm actually a Web developer and took the job just in desperation to have one (I'm still quite young and just finished 2nd year of University). From the 3rd day my boss realised that I'm not into that stuff at all and since he had an idea of a web based app we started to plan it. I estimated that it shouldn't take me longer than two months to do it, but as I was making it we soon realised that we want to add more and more stuff to make it even better. So the development on my own lasted for about 4 months, but then it became an enterprise size app and we hired another programmer to work along me. The guy was awesome at what he did, but because I was assigned to be programmer/project manager I had to set up milestones with deadlines and we missed most of them, because most of the time it was too much work, and my lack of experience kept me setting really optimistic deadlines. We still kept adding features and had changed the architecture of the application twice. My boss is a great guy and he gets that when we add features it expands the time frame in which things should be done so he wasn't angry at me nor the other guy. But I was feeling bad (I still am) that I suck at planning. I gained loads of experience from the programming side, but I still lack the management/planning skills which make me go nuts. So over the last year I have dedicated probably about 8 months of work to this app (obviously my studies affected it) and we're launching as a closed beta this month. So my question is how do I get better at planning/managing a project, how do you estimate the times? What do you take into consideration when setting goals. I'm working alone again because the other guy moved from the city. But I'm sure we'll be hiring to help me maintain it so I need to get better at it. Any hints, points or anything on the topic are appreciated.

• Cleaning Up After Chrome

  - by Mark Treadwell

  I find Google Chrome, which I have no interest in, is continually getting installed on machines in my house, mostly due to Adobe Shockwave bringing it along as an install package. (Family members are agreeing to the download, not realizing the Chrome is getting dropped as well.) My major issue after uninstalling Chrome is that you can no longer click on links in Outlook emails. There is a lot on the web about this, and Google has not been proactive at fixing their uninstaller. I have now added a registry file to my Win64 systems to reset the problem registry keys and clear the error. This registry file is pretty simple. It merely resets HKEY_CURRENT_USER\Software\Classes\.htm, HKEY_CURRENT_USER\Software\Classes\.html, and HKEY_CURRENT_USER\Software\Classes\.shtml back to their default values of "htmlfile". Chrome takes over the handling of these file extensions because its default install is to make itself the default web browser. The Chrome uninstalled fails to clear/reset them. In troubleshooting this, I looked in my registry based on the web info on the Chrome uninstall problem. Since my system had never had Chrome installed, my registry did not have the problem keys. To troubleshoot, I installed (ugh!) and uninstalled Chrome. Sure enough, Chrome left the expected debris with a value string of "ChromeHTML.PR2EPLWMBQZK3BY7Z2BFBMFERU" or something similar. Resetting these values fixed the problem. I see that Chrome leaves quite a bit of debris behind in the registry. I guess it is creating the keys then leaving them behind, even though their presence (with bad data) subsequently affects operations.

• Should we encourage coding styles in favor of developer's autonomy, or discourage it in favor of consistency?

  - by Saeed Neamati

  A developer writes if/else blocks with one-line code statements like: if (condition) // Do this one-line code else // Do this one-line code Another uses curly braces for all of them: if (condition) { // Do this one-line code } else { // Do this one-line code } A developer first instantiates an object, then uses it: HelperClass helper = new HelperClass(); helper.DoSomething(); Another developer instantiates and uses the object in one line: new HelperClass().DoSomething(); A developer is more easy with arrays, and for loops: string[] ordinals = new string[] {'First', 'Second', 'Third'}; for (i = 0; i < ordinals.Length; i++) { // Do something } Another writes: List<string> ordinals = new List<string>() {'First', 'Second', 'Third'}; foreach (string ordinal in ordinals) { // Do something } I'm sure that you know what I'm talking about. I call it coding style (cause I don't know what it's called). But whatever we call it, is it good or bad? Does encouraging it have an effect of higher productivity of developers? Should we ask developers to try to write code the way we tell them, so to make the whole system become style-consistent?

• ERP/CRM Systems. Desktop Based ? Web based? [closed]

  - by Parhs

  I have seen 2-3 ERPs in action. I am wondering what is better. Desktop based application or webbased displayed on a browser. My first experience was with a web based ERP when i was 14 years old.. It was web based and terribly slow... For most simple task you had to do lots of clicks... no keyboard support ..... Pages took ages to load. Last year I worked for migrating to a newer computer some old terminal based cobol application. The computer that worked till today and still has no problem was from 1993. The user interface ofcourse was textbased.. The speed that guys placed orders was amazing! just typing the name of the customer , then 5-10 keys to add a product to order.... Comparing to this ERP the page for placing orders Link (click sales orders) seems terribly slow to add a product... No keyboard shortcut works to save what you added and generally I believe you need 4 times more time to place an order compared to the text interface... Having to use both mouse and keyboard for this task is BAD and sadistic... So how can the heck these people ever use a system like that ??? So in the long run desktop application seems the only way... Of course browsers support shortcuts but the way to overide the defaults that browsers uses isn't cross compatible... That is a huge problem. Finnaly, if we MUST/forced use cloud in near future what about keyboard shortcuts?? I feel confused... I have seen converters of desktop applications to browser applications but are SLOW as hell... The question is what about user friendliness? What kind of application would you use?

• Removing spam external links after pharma hack?

  - by Beatchef

  Back in February my work's site was attacked by a pharma hack at the shared hosting end. I managed to find the placed file and the reference to run it in one of our files. I deleted this file, deleted and redownloaded all of the plugins and themes and reinstalled Wordpress. However I could never find the database entries no matter what I have read up on. Searching for known entries or for drug names backwards etc. On the Google and Bing end I have managed to deny and delete the entries and cache of most if not all of the bad links that the hack managed to instantly SEO to death (why don't these guys work legit and make more money?) However the one thing that is remaining is external links on the homepage that are invisible except when the site is viewed in google cache or scanned with unmaskparasites.com (and says that the external links are safe even though they're obviously not!). http://www.UnmaskParasites.com/security-report/?page=kmcharityteam.co.uk All sorts of website scans say there's nothing wrong with it and I can't find the source of the links in the header or footer or anywhere in the theme. I've searched for the links in the database but no use there either and they change every day so really I'd have to be looking for a generator? Does anybody have any advice or a solution for removing these links? Thanks!

• I have discovered a fundamental truth about TV shows and plots

  - by Steve Loethen

  For years, we have all known (okay, maybe I give people too much credit) that there is a very small finite number of plots.  I propose a project.  Let’s use the blogosphere to catalog those plotlines, and then find and document the episodes of shows that use them, including the show title. As evidence, how many shows have used the following plot line:? The standard “evil twin” plotline?  Once relegated to soaps, it has show up in crime shows, with the twist of DNA.  Step one, concentrate one this one.  Tell me about every show you recall that has used this plot.  I will collect and document the shows on my website (www.loethen.net) and we can build a database of the plots. Step two, what other common themes should I offer up?  How about the bigamist plot line?  The “bad guy was dead” plot line (revenge from the dead"?  The “vast government conspiracy” plotline? Let the games begin….

• Poor backlink profile - search rankings not updated for 2+ months

  - by fistameeny

  I am carrying out some work on a website that is a PR2 with a few good quality, relevant backlinks (PR4-6). It has a presence on Twitter that is updated regularly, a Google Places listing, and listings on some decent directories (Qype etc). The site was rebuilt into Drupal 7 two months ago, with all the basics done - URL rewriting, XML Sitemap submitted to Google, and most importantly, good quality, structured content. I've noticed that Google is still showing "old" URL's from the previous version of the site that was ditched 8 weeks ago. I think the site may be penalised under the Penguin update, as a previous SEO company created many low quality links from link farms/directories. My question is what the correct way to deal with this is. Bing Webmaster Tools can "disavow" links, and I guess I can attempt to contact the link farms to have them removed. I've already submitted a request to Google to request that we have the penalty removed as we're trying to tidy up a bad history. We submit updated sitemaps to Google and Bing daily, and have built some further decent quality, relevant links. Is there anything further I can do?

• Providing SSH tunnling, what to think about when configuring Ubuntu Server

  - by bigbadonk420

  Recently I've considered, mostly as a pet project, to set up accounts for a closed group of users via SSH to my box with the purpose of SSH tunnling things like web traffic -- some of it for friends that live abroad and perhaps also to help some people bypass national censorship. There's some things I imagine that I need to do, such as: Disabling shell access by setting the shell to /bin/false or similar. Get some software that can track bandwidth usage on a per-user basis historically Make sure that each user can only use a certain amount of bandwidth. The reason I'm posting here to begin with is to look around and get some pointers regarding what kind of things I should read up on, as well as hearing if there are any software recommendations for doing what I'm trying to do. I already know a bit since I've actually gotten SSH tunnling up and running already, I just don't feel like letting it loose to other people without restrictions and some basic monitoring. I'm primarily trying to learn here, so if you think this is a Very Bad Idea (or if you have a better idea on how to do this) then by all means say so, but please include some information on how to do it :) (I'm also open to trying things like OpenVPN but it seems really hard to set up, also I've heard SSH more often works in locked down environments)

• How do I mount a CIFS share via FSTAB and give full RW to Guest

  - by Kendor

  I want to create a Public folder that has full RW access. The problem with my configuration is that Windows users have no issues as guests (they can RW and Delete), my Ubuntu client can't do the same. We can only write and read, but not create or delete. Here is the my smb.conf from my server: [global] workgroup = WORKGROUP netbios name = FILESERVER server string = TurnKey FileServer os level = 20 security = user map to guest = Bad Password passdb backend = tdbsam null passwords = yes admin users = root encrypt passwords = true obey pam restrictions = yes pam password change = yes unix password sync = yes passwd program = /usr/bin/passwd %u passwd chat = *Enter\snew\s*\spassword:* %n\n *Retype\snew\s*\spassword:* %n\n *password\supdated\ssuccessfully* . add user script = /usr/sbin/useradd -m '%u' -g users -G users delete user script = /usr/sbin/userdel -r '%u' add group script = /usr/sbin/groupadd '%g' delete group script = /usr/sbin/groupdel '%g' add user to group script = /usr/sbin/usermod -G '%g' '%u' guest account = nobody syslog = 0 log file = /var/log/samba/samba.log max log size = 1000 wins support = yes dns proxy = no socket options = TCP_NODELAY panic action = /usr/share/samba/panic-action %d [homes] comment = Home Directory browseable = no read only = no valid users = %S [storage] create mask = 0777 directory mask = 0777 browseable = yes comment = Public Share writeable = yes public = yes path = /srv/storage The following FSTAB entry doesn't yield full R/W access to the share. //192.168.0.5/storage /media/myname/TK-Public/ cifs rw 0 0 This doesn't work either //192.168.0.5/storage /media/myname/TK-Public/ cifs rw,guest,iocharset=utf8,file_mode=0777,dir_mode=0777,noperm 0 0 Using the following location in Nemo/Nautilus w/o the Share being mounted does work: smb://192.168.0.5/storage/ Extra info. I just noticed that if I copy a file to the share after mounting, my Ubuntu client immediately make "nobody" be the owner, and the group "no group" has read and write, with everyone else as read-only. What am I doing wrong?

• Wrong resolution for Lightdm/GDM on Ubuntu 13.04 using HDMI

  - by f03lipe

  I've tried all the solution I could find on the matter so far, but the error persists. My problem is that the login screen (both under gdm and lightdm) runs with the wrong resolution, even though all is fine when I log in. The error occurs solely when I have my HDMI cable connected to my other screen. The login screen resolution becomes 1024x768 (for my 1366x768 laptop screen) and mirrored on my screen, which is 1920x1080. I've had this issue on version 12.04 (the last one before I upgraded to 13.04), but I got it fixed by adding the xrandr commands on the begining of the /etc/gdm/Init/Default file. This doesn't seem to work anymore. I've also tried telling lightdm to run a script fixing the resolution with xrandr (by editing /etc/lightdm/lightdm.conf), but lightdm crashes, and I'm forced to log in with low graphic settigs. Hint: when ubuntu is loading, the resolution starts OK, then goes bad right before the login screen is initialized. Does that mean that there's nothing wrong with my graphic cards? What do you think? Cheers!

• Is there a canonical source supporting "all-surrogates"?

  - by user61852

  Background The "all-PK-must-be-surrogates" approach is not present in Codd's Relational Model or any SQL Standard (ANSI, ISO or other). Canonical books seems to elude this restrictions too. Oracle's own data dictionary scheme uses natural keys in some tables and surrogate keys in other tables. I mention this because these people must know a thing or two about RDBMS design. PPDM (Professional Petroleum Data Management Association) recommend the same canonical books do: Use surrogate keys as primary keys when: There are no natural or business keys Natural or business keys are bad ( change often ) The value of natural or business key is not known at the time of inserting record Multicolumn natural keys ( usually several FK ) exceed three columns, which makes joins too verbose. Also I have not found canonical source that says natural keys need to be immutable. All I find is that they need to be very estable, i.e need to be changed only in very rare ocassions, if ever. I mention PPDM because these people must know a thing or two about RDBMS design too. The origins of the "all-surrogates" approach seems to come from recommendations from some ORM frameworks. It's true that the approach allows for rapid database modeling by not having to do much business analysis, but at the expense of maintainability and readability of the SQL code. Much prevision is made for something that may or may not happen in the future ( the natural PK changed so we will have to use the RDBMS cascade update funtionality ) at the expense of day-to-day task like having to join more tables in every query and having to write code for importing data between databases, an otherwise very strightfoward procedure (due to the need to avoid PK colisions and having to create stage/equivalence tables beforehand ). Other argument is that indexes based on integers are faster, but that has to be supported with benchmarks. Obviously, long, varying varchars are not good for PK. But indexes based on short, fix-length varchar are almost as fast as integers. The questions - Is there any canonical source that supports the "all-PK-must-be-surrogates" approach ? - Has Codd's relational model been superceded by a newer relational model ?

• Law of Demeter confusion [duplicate]

  - by user2158382

  This question already has an answer here: Rails: Law of Demeter Confusion 4 answers I am reading a book called Rails AntiPatterns and they talk about using delegation to to avoid breaking the Law of Demeter. Here is their prime example: They believe that calling something like this in the controller is bad (and I agree) @street = @invoice.customer.address.street Their proposed solution is to do the following: class Customer has_one :address belongs_to :invoice def street address.street end end class Invoice has_one :customer def customer_street customer.street end end @street = @invoice.customer_street They are stating that since you only use one dot, you are not breaking the Law of Demeter here. I think this is incorrect, because you are still going through customer to go through address to get the invoice's street. I primarily got this idea from a blog post I read: http://www.dan-manges.com/blog/37 In the blog post the prime example is class Wallet attr_accessor :cash end class Customer has_one :wallet # attribute delegation def cash @wallet.cash end end class Paperboy def collect_money(customer, due_amount) if customer.cash < due_ammount raise InsufficientFundsError else customer.cash -= due_amount @collected_amount += due_amount end end end The blog post states that although there is only one dot customer.cash instead of customer.wallet.cash, this code still violates the Law of Demeter. Now in the Paperboy collect_money method, we don't have two dots, we just have one in "customer.cash". Has this delegation solved our problem? Not at all. If we look at the behavior, a paperboy is still reaching directly into a customer's wallet to get cash out. Can somebody help me clear the confusion. I have been searching for the past 2 days trying to let this topic sink in, but it is still confusing.

• IRQ Conflicts Causing Video Card and Boot Problems?

  - by sanpatricio

  tl;dr - I have 4 devices sharing 1 IRQ. Is this bad and how do I tell the BIOS to stop it? Background: I have an old Dell GX280 dual Pentium 4 that I (semi) resurrected last weekend with an installation of Ubuntu 12.04. Everything was going fine the first several hours until a problem that plagued me when WinXP was on that machine happened -- it froze. Completely froze. None of the myriad of ways I have found here on askubuntu helped me to regain control except a long-press of the power button to shut it off. Clearly, this wasn't a software/WinXP issue. After much googling, I found that hardware conflicts can often cause this sort of total lock-up and with all the odd blocks of yellow and flecks of color showing on my screen (both WinXP and Ubuntu) I figured my old GeForce 7600 was failing and causing me these odd issues. (A good canned-air dusting of the entire interior fixed the color fleck problem) Again, through much googling and numerous answers found on askubuntu, I somehow stumbled my way onto the lshw command. After going through it, line by line, I found that I have four devices sharing IRQ 16: eth0, wlan0, ide0 (DVD-RW), and my video card. In hindsight, I can recall weird instances of my Ethernet connection to another computer not working when I thought it should. I never full troubleshot those issues so it could be a coincidence. The other thing that has been plaguing me since installing Ubuntu (wasn't there during WinXP) has been periodic moments of my monitor getting no signal from Ubuntu during boot. The first couple days, it would disappear after the Dell boot screen and reappear at Ubuntu login. Now, it disappears after the Dell boot screen and doesn't return at all -- I have to hit F12 where I can load a safe mode version of Ubuntu and get more details like dmesg and lsdev. I also ran memtest86 overnight and woke up to zero errors, so failing RAM is out. Where do I go from here?

• Thoughts on exception handling.

  - by AndyScott

  Was working on a windows form app (something I haven't done in a while), adding threading and logging so that it would work a little more smoothly and have a record of who did what.  I was just about at the point where I was going to check it into source control when I noticed that the Output window was showing "A first chance exception of type 'System.InvalidCastException' occurred in mscorlib.dll", so I googled it.  In reading some threads about the error, I came across the following comment and it got me thinking: "In addition, while they should be avoided if possible, exceptions are a quite legitimate part of program execution. It's their going unhandled that is a real issue, because that means crashy, crashy." How do you normally use exception handling?  I feel that exceptions are intended to handle errors in code (in my experience generally related to bad data making its way into the system).  Now don't get me wrong, I understand that exceptions happen and should be dealt with, but I feel that they are a "last resort" to keep a program from crashing, but should never be a way to pass data or continue logical processing that could be handled in standard code flow. I mention this, because I have seen it done. What do you think?

• What should you do when presented with a horrible design?

  - by plua

  Our firm makes websites. We also design websites. But sometimes our client brings his/her own design. This is often made by an in-house designer, or it is the same design they used for something else. However, sometimes these designs look awful. And I am talking really unprofessional, unbalanced, uncool. But the client really wants this design. I really do not like working with a design that is so awful. It takes away all pleasure in coding. You code. You check the demo. Works great. Looks awful. It's just not fun. And ultimately the client might be happy, but 1) I do not feel proud of the final product and 2) the community sees you 'develop' ugly websites, which is bad for your image. Anybody experiencing this kind of stuff? What do you recommend? I've been thinking: Blocking these clients. If somebody has an 'own' design, ask to see it first. Then somehow politely decline. Drawback: you lose a client. Create a new design. Have our in-house designers work one something really cool. Drawbacks: client would need to pay for this (without asking for it), or it will be declined and the company loses time = money. And it might come as an insult if you propose a new design out of the blue. THEIR designer won't like it for sure. Put a clear disclaimer at the bottom of the site: Website design by XXXXX, Website development by US. Helps for the community-impact (if people pay attention), but not for the uneasy feeling.

• Naming conventions: camelCase versus underscore_case ? what are your thoughts about it?

  - by poelinca

  I've been using underscore_case for about 2 years and I recently switched to camelCase because of the new job (been using the later one for about 2 months and I still think underscore_case is better suited for large projects where there are alot of programmers involved, mainly because the code is easyer to read). Now everybody at work uses camelCase because (so they say) the code looks more elegant . What are you're thoughts about camelCase or underscore_case p.s. please excuse my bad english Edit Some update first: platform used is PHP (but I'm not expecting strict PHP platform related answers , anybody can share their thoughts on which would be the best to use , that's why I came here in the first place) I use camelCase just as everibody else in the team (just as most of you recomend) we use Zend Framework which also recommends camelCase Some examples (related to PHP) : Codeigniter framework recommends underscore_case , and honestly the code is easier to read . ZF recomends camelCase and I'm not the only one who thinks ZF code is a tad harder to follow through. So my question would be rephrased: Let's take a case where you have the platform Foo which doesn't recommend any naming conventions and it's the team leader's choice to pick one. You are that team leader, why would you pick camelCase or why underscore_case? p.s. thanks everybody for the prompt answers so far

• What technical details should a programmer of a web application consider before making the site public?

  - by Joel Coehoorn

  What things should a programmer implementing the technical details of a web application consider before making the site public? If Jeff Atwood can forget about HttpOnly cookies, sitemaps, and cross-site request forgeries all in the same site, what important thing could I be forgetting as well? I'm thinking about this from a web developer's perspective, such that someone else is creating the actual design and content for the site. So while usability and content may be more important than the platform, you the programmer have little say in that. What you do need to worry about is that your implementation of the platform is stable, performs well, is secure, and meets any other business goals (like not cost too much, take too long to build, and rank as well with Google as the content supports). Think of this from the perspective of a developer who's done some work for intranet-type applications in a fairly trusted environment, and is about to have his first shot and putting out a potentially popular site for the entire big bad world wide web. Also, I'm looking for something more specific than just a vague "web standards" response. I mean, HTML, JavaScript, and CSS over HTTP are pretty much a given, especially when I've already specified that you're a professional web developer. So going beyond that, Which standards? In what circumstances, and why? Provide a link to the standard's specification.

• Is there any way to send a column value from outer query to inner sub query? [closed]

  - by chetan

  'Discussions' table schema title description desid replyto upvote downvote views browser used a1 none 1 1 12 - bad topic b2 a1 2 3 14 sql database a3 none 4 5 34 - crome b4 a3 3 4 12 The above table has two types of content types Main Topics and Comments. Unique content identifier 'desid' used to identify that its a main topic or a comment. 'desid' starts with 'a' for Main Topic and for comment 'desid' starts with 'b'. For comment 'replyto' is the 'desid' of main topic to which this comment is associated. I like to find out the list of the top main topics that are arranged on the basis of (upvote+downvote+visits+number of comments to it) addition. The following query gives top topics list in order of (upvote+downvote+visits) select * with highest number of upvote+downvote+views by query "select * from [DB_user1212].[dbo].[discussions] where desid like 'a%' order by (upvote+downvote+visited) desc For (comments+upvote+downvote+views ) I tried select * from [DB_user1212].[dbo].[discussions] where desid like 'a%' order by ((select count(*) from [DB_user1212].[dbo].[discussions] where replyto = desid )+upvote+downvote+visited) desc but it didn't work because its not possible to send desid from outer query to inner subquery. How to solve this? Please note that I want solution in query language only.

• How to mount private network shares on login?

  - by bainorama

  I've read all the existing entries I could find on using pam_mount but none of them seem to work for me. I'm trying to automatically mount shares on my local NAS at user login time. The usernames and passwords on my NAS shares match my local user name and password, but there is no LDAP/AD server. My pam_mount.conf has the following: <volume fstype="cifs" server="bain-brain" path="movies" user="*" sgrp="bains" mountpoint="/home/%(USER)/movies" options="user=%(USER),dir_mode=0700,file_mode=700,nosuid,nodev" /> When I login, I see the following in /var/log/auth.log: Oct 13 10:21:26 bad-lattitude lightdm: pam_mount(misc.c:380): 29 20 0:20 / /home/alastairb/movies rw,nosuid,nodev,relatime - cifs //bain-brain/movies rw,sec=ntlm,unc=\\bain-brain\movies,username=alastairb,uid=1000,forceuid,gid=1000,forcegid,addr=10.1.1.12,file_mode=01274,dir_mode=0700,nounix,serverino,rsize=61440,wsize=65536,actimeo=1 The folder /home/alastairb/movies is present but empty (can't see the files which are on the NAS in the respective share folder). In Nautilus, the share is shown in the sidebar under "Computer", and clicking on this takes me to the correct folder, but again, its empty. Any ideas as to what I'm doing wrong?
