• Ajax Div Maintain Height

  - by pws5068

  Greetings, I have a list of user comments on a page, with a next button which makes an Ajax call to get the second set of comments. The problem is, the height of the comments div temporarily becomes very small while the loading bar is in place. This makes the user need to scroll back down to see the new comments The issue can be seen at the bottom of this page by clicking "Next" comments. Is there a way to force the div to maintain its height through Javascript? I do not want to hard code the div height in case a page has 3 or less comments.

• OT: US Banks: Bank Routing Number and BIC/SWIFT

  - by Konerak

  I know it is a bit offtopic, but I've been having a hard time finding more information to this question, and since this site is visited by a lot of people from the United States, you guys might know/find the answer more easily. Banks in europe each have a SWIFT Number, while US Banks use Routing Numbers. This leads to following questions: Does each bank in the US also carry a BIC number? (SWIFT) Is there a 1-1 relationship between BIC and SWIFT? Is there a list of these numbers somewhere? (background information: we're adding international payments to our bookkeeping application. Users can add international suppliers, but my boss prefered not to change the current supplier table but to have the ROUTING NUMBER in another table, with as PK the BIC. I'm wondering if BIC is a valid choice, or if it should just be BANK ACCOUNT NUMBER.)

• How do you keep a balance between working, training, health and family?

  - by Jim Burger

  One trend I see in the awesome developers I've met, is that they devote inordinate amounts of time to coding at the expense of (usually) their health. Personally, I also find it hard to motivate myself to keep healthy. Every now and again, I meet a fantastic coder who has it clocked; they are up to date with the latest dev news, have time to read about good programming practices, and to finish it off, have happy wives/husbands and families. How do you guys/gals manage it in the short 24 hours a day that we all have?

• Young people using Emacs?

  - by bigmonachus

  I am a college student that has fallen in love with Emacs. I have used IDEs in the past, and although features like Intellisense made the switch to Emacs very hard, I now think that Emacs is much more powerful, and features like Intellisense can be pretty closely matched by various modes depending on language (and I am not referring to M-/). I am happily writing Elisp code for everything that I need that isn't provided by modes or by Emacs itself and I love the way that it adapts and molds to my needs. However, I do think that its main disadvantage is the fact that it has a pretty steep learning curve and that most new programmers will not even begin to learn it out of many common misconceptions. So, I want to know the opinions of young people (or any person who didn't start using Emacs before there were IDEs) that are Emacs users. Just to get some reassurance that Emacs is not dead within our Eclipse-loving generation =). (Opinions of users of any other highly extensible editor like Jedit are also welcome)

• MySQL Student database beginner SQL employment expectations

  - by sammysmall

  Background, Student pursuing BSIT degree, employer expectations, entry level. I would like to solicit opinions from this forum as to what your professional expectations are as regards an entry level position in working in the database realm... I see many job opportunities that require a minimum of 2 or more years experience, how does one go about obtaining this experience (I have tried very hard to maintain a minimum 3.70+ GPA) but have ZERO work experience in this field... I spend non school time working in VB and SQL to try and increase my proficiency. I have considered postponing my job search until I obtain certifications from brainbench etc... Any criticism and or advise is welcomed... Again I have no experience in database other than undergrad work in class. Thank you for your time sammysmall

• Version Control for developers new to source control

  - by Daisetsu

  I've been writing code for a few years now and our backup strategy has been to zip the entire code directory up every few days and put it somewhere else on your hard drive, or occasionally upload it to some online file hosting service. Unfortunately the file hosting service got canceled without telling me and we lost years of backups. It's come down to the point where I finally have to learn to use version control. The only problems are My boss really doesn't like SVN, he tried it and it had a high learning curve (at least his client). We need a reliable place to host it (we can pay a reasonable amount). Can someone suggest what may be the best version control system and client for a newbie which won't be too annoying. Second what is a good remote version control service?

• Session variable getting lost using Firefox, works in IE

  - by user328422

  I am setting a Session variable in an HttpHandler, and then getting its value in the Page_load event of an ASPX page. I'm setting it using public void ProcessRequest(HttpContext context) { HttpPostedFile file = context.Request.Files["Filedata"]; context.Session["WorkingImage"] = file.FileName; } (And before someone suggests that I check the validity of file.FileName, this same problem occurs if I hard-code a test string in there.) It's working just fine in IE, but in Firefox the Session Variable is not found, getting the "Object reference not set to an instance of an object" error in the following code: protected void Page_Load(object sender, EventArgs e) { string loc = Session["WorkingImage"].ToString(); } Has anyone encountered this problem - and hopefully come up with a means for passing the session variable?

• Building big, immutable objects without using constructors having long parameter lists

  - by Malax

  Hi StackOverflow! I have some big (more than 3 fields) Objects which can and should be immutable. Every time I run into that case i tend to create constructor abominations with long parameter lists. It doesn't feel right, is hard to use and readability suffers. It is even worse if the fields are some sort of collection type like lists. A simple addSibling(S s) would ease the object creation so much but renders the object mutable. What do you guys use in such cases? I'm on Scala and Java, but i think the problem is language agnostic as long as the language is object oriented. Solutions I can think of: "Constructor abominations with long parameter lists" The Builder Pattern Thanks for your input!

• Ideas on collaborating with small number of people

  - by Mark Szymanski

  Hi, I am collaborating with someone on a project and currently use Skype for collaboration. I like it because we can be on a call to say things that are hard to say by typing out. We can share our screens so we can help with code writing. And we can use the text chat to copy-paste code between each other. We also use Subversion for version control. I just wanted to know what other people used for collaborating with others so I could see whats out there to use. Thanks!

• Lightweight Object->Database in python

  - by pehrs

  I am in need of a lightweight way to store dictionaries of data into a database. What I need is something that: Creates a database table from a simple type description (int, float, datetime etc) Takes a dictionary object and inserts it into the database (including handling datetime objects!) If possible: Can handle basic references, so the dictionary can reference other tables I would prefer something that doesn't do a lot of magic. I just need an easy way to setup and get data into an SQL database. What would you suggest? There seems to be a lot of ORM software around, but I find it hard to evaluate them.

• How to transform phrases and words into MD5 hash?

  - by brilliant

  Can anyone, please, explain to me how to transform a phrase like "I want to buy some milk" into MD5? I read Wikipedia article on MD5, but the explanation given there is beyond my comprehension: "MD5 processes a variable-length message into a fixed-length output of 128 bits. The input message is broken up into chunks of 512-bit blocks (sixteen 32-bit little endian integers)" "sixteen 32-bit little endian integers" is already hard for me. I checked the article on little endians and didn't understand a bit. However, the examples of some phrases and their MD5 hashes are very nice: MD5("The quick brown fox jumps over the lazy dog") = 9e107d9d372bb6826bd81d3542a419d6 MD5("The quick brown fox jumps over the lazy dog.") = e4d909c290d0fb1ca068ffaddf22cbd0 Can anyone, please, explain to me how this MD5 algorithm works on some very simple example? And also, perhaps you know some software or a code that would transform phrases into their MD5. If yes, please, let me know.

• How to Use JQuery Click Event on Button in an AJAX Form

  - by dpierre23

  I admittedly don't know much about JQuery but I have an AJAX page where I need to trigger a click event when someone clicks a button, but because the button is not there on the initial page load, I'm having issues using the click event. In my code, I just want to run a function when a button is clicked. <script type="text/javascript"> //Run function when button is clicked $(document).ready(function() { $("#idOfButton").click(function() { doSomething(); }); }); //The function I want ran when page visitor clicks button function doSomething() { //Do Something } </script> Obviously this code doesn't work, but any suggestions on how to use .click? I'm only able to insert JS via a tag management system, so I can't hard code anything into the page. Also, the JQuery version is 1.4, so I can't use .on. Thanks for your help.

• Need Database Help - A second opinion - thank you

  - by user287745

  i have designed an er model and then normalized it till the BCNF and converted it into tables using vs08. my problem is i do not know from where to get the normalized database checked to see if it has no mistakes in normalization- can not be further normalized. please do not give answers such as- ask a friend- ask your professor- do not have these resources available- it is very very hard and really time consuming waiting for the relevant person to be available. so are there any sites from where i can ask help from other designers- people like you to check the normalized database? please note:- it should be free, sorry for accept rate, was not aware of accepting the answers, all the help is appreciated thank you

• What is technically more advanced: Brainf*ck or Assembler?

  - by el ka es

  I wondered which of these languages is more powerful. With powerful I don't mean the readability, assembler would be naturally the winner here, but something resulting from, for example, the following factors: Which of them is more high-level? (Both aren't really but one has to be more) Who would be the possibly fastest in compiled state? (There is no BF compiler out there as far as I know but it wouldn't be hard writing one I suppose) Which of the both has the better code length/code action ratio? What I mean is If you get to distracted by the, compared to Brainf*ck, improved readability of assembler, just think of writing plain binary/machine code as what assembler assembles to. Both languages are so basic that it should be possible to answer the question(s) in a rather objective view, I hope.

• Detect block size for quota in Linux

  - by Chen Levy

  The limit placed on disk quota in Linux is counted in blocks. However, I found no reliable way to determine the block size. Tutorials I found refer to block size as 512 bytes, and sometimes as 1024 bytes. I got confused reading a post on LinuxForum.org for what a block size really means. So I tried to find that meaning in the context of quota. I found a "Determine the block size on hard disk filesystem for disk quota" tip on NixCraft, that suggested the command: dumpe2fs /dev/sdXN | grep -i 'Block size' or blockdev --getbsz /dev/sdXN But on my system those commands returned 4096, and when I checked the real quota block size on the same system, I got a block size of 1024 bytes. Is there a scriptable way to determine the quota block size on a device, short of creating a known sized file, and checking it's quota usage?

• TortoiseGit - representing branches in a tree - visual issue

  - by richard

  This is a little hard to explain with text, but I'll do my best, and you try to keep up; if something isn't clear at first, don't hesitate to ask, and I'll try to clarify. When TortoiseGit has one branch it looks approximately like this: o | o <-- a commit sign | x When I split my work into a new branch, it looks like this: o | o--o | x when I split, from the master to another new branch it looks like this: o--o | o--o | x Is there a way for every new branch that I make, and work on, to have its own "line" ... what I mean: o-----o | o--o | x so they don't "vertically overlap". So that every branch, has its own vertical line I can follow (for some reason this looks rather confusing to me, the way it's done now). Do any other Git clients for Windows do this differently ?

• Is there any specific available method in jsp/Servlet API which tell you from which page the request

  - by anubhavjain86

  Hi, I have been working in Oracle iStore from past 4 months and i have been managing the application without any IDE (basically doing all the chores on notepad only because application has been designed poorly and no IDE can support it). Since the coding is done on simple notepad files it is very hard to find out the bugs in the application. I am facing a problem that i have not idea which jsp page redirect the control to which jsp page. For instance, there are two jsp pages A.jsp and other is B.jsp. Now the browser is currently displaying A.jsp. When the user click on submit button (available on A.jsp) the form submits and redirects the control to B.jsp. Now my problem is that i know i am coming on B.jsp but, i don't know that A.jsp is redirecting the control to B.jsp. Is there an method available in Servlet API which tells Which jsp is redirecting the control to B.jsp? Sorry for making you read so much long story :( appreciate ur help in advance Best Regards Anubhav

• DateTime: Require the user to enter a time component

  - by Heinzi

  Checking if a user input is a valid date or a valid "date + time" is easy: .NET provides DateTime.TryParse (and, in addition, VB.NET provides IsDate). Now, I want to check if the user entered a date including a time component. So, when using a German locale, 31.12.2010 00:00 should be OK, but 31.12.2010 shouldn't. I know I could use DateTime.TryParseExact like this: Dim formats() As String = {"d.M.yyyy H:mm:ss", "dd.M.yyyy H:mm:ss", _ "d.MM.yyyy H:mm:ss", "d.MM.yyyy H:mm:ss", _ "d.M.yyyy H:mm", ...} Dim result = DateTime.TryParseExact(userInput, formats, _ Globalization.CultureInfo.CurrentCulture, ..., result) but then I would hard-code the German format of specifying dates (day dot month dot year), which is considered bad practice and will make trouble should we ever want to localize our application. In addition, formats would be quite a large list of all possible combinations (one digit, two digits, ...). Is there a more elegant solution?

• Dump characters (glyphs) from TrueType font (TTF) into bitmaps

  - by jpatokal

  I have a custom TrueType font (TTF) that consists of a bunch of icons, which I'd like to render as individual bitmaps (GIF, PNG, whatever) for use on the Web. You'd think this is a simple task, but apparently not? There is a huge slew of TTF-related software here: http://cg.scs.carleton.ca/~luc/ttsoftware.html But it's all varying levels of "not quite what I want", broken links and/or hard to impossible to compile on a modern Ubuntu box -- eg. dumpglyphs (C++) and ttfgif (C) both fail to compile due to obscure missing dependencies. Any ideas?

• Connecting to a SQL Server Compact Edition (.sdf) from an MFC application

  - by Hazerd

  Hey ! I'm building an MFC app in Visual Studio 2008 which classifies textures and I need some sort of lightweight database to hold the characteristics (just some doubles and strings) which can be: -carried around with the app on different computers; -be able to perform queries on it from the app (searches , updates ,inserts ,etc); Currently I'm looking into SQL compact edition because it was very easy to create from Visual Studio ( I also need only one table) but I having a hard time connecting and updating the db from C++. This is what I've found on msdn regarding C++ and SQLCE: public: void createSqlCeConnection(){ SqlCeConnection* myConnection = new SqlCeConnection(); myConnection->ConnectionString = "DataSource = blabla.sdf"; MessageBox::Show(String::Format( S"Connection State: {0}", __box(myConnection->State))); } Unfortunately my experience with .net apps is pretty limited. Hopefully you bright minds could tell me if I'm on the right path and what links and includes should I add for this to work with an C++ MFC projects. Thanks !

• Django development targeting both the Google App Engine and Py2Exe

  - by bp

  I must hand in a mostly static database-driven website on a topic on my choice by the end of June as both a hosted version live on the internet and a stored version on a cd-rom. "Ease of launching" is one of the bulletpoints for evaluation of the project. (Yeah, I know.) I and my project mate are currently comparing various frameworks and technologies to help us deliver and deploy this as quickly and painlessly as possible. Theoretically, by using Django, I can target the Google App Engine (which I guess would provide us reliable, free-as-in-beer hosting) or the Py2Exe system + SQLLite (which I guess would make starting the website server from disk as hard as doubleclicking on an .exe file). Sounds better than what PHP and MySQL can ever hope to bring me, right? However, we need to target both Py2Exe and the GAE. How much of the differencies between these wildly different configurations are hidden by Django? What will instead require special attention and possibly specialized code on my end?

• Mac OS X: Intel vs. PPC marketshare

  - by benc

  I was looking at my plugins, and ended up looking at Silverlight on several Mac systems. What I noticed (from Wikipedia), was that only Silverlight 1 runs on PPC. Without knowing about the technical details and trade-offs, I was surprised. On its face, if you build Silverlight 1 for PPC and Intel, would it have been hard to continue to support both chipsets? So, assuming this was a decision based on marketshare, I tried to search for information on the Mac OS PPC vs. Intel marketshare, but could not find anything on point. Does anyone here have an idea what the ratio is? It seems like the most important architectural/product decision you would make for a Mac OS X product.

• php regex expression to get title

  - by 55skidoo

  I'm trying to strip content titles out of the middle of text strings. Could I use regex to strip everything out of this string except for the title (in italics) in these strings? Or is there a better way? Joe User wrote a blog post called The 10 Best Regex Expressions in the category Regex. Jane User wrote a blog post called Regex is Hard! in the category TechProblems. I've tried to come up with a regex expression to cover this, but I think it might need two. The trick is that the text in bold is always the same, so you could search for that, like this: regex: delete everything before and including wrote a blog post called regex: delete in the category and everything after it.
