• After pip installing uWSGI there's no /etc/uwsgi/ directory - how can I use apps-enabled?

  - by orokusaki

  I've been using apt-get install uwsgi to install uWSGI. Today, I realized I needed a feature that's not available until uWSGI 1.1, and Ubuntu 12.04.1 doesn't have anything after 1.0.x, at least according to my apt-get install uwsgi=1.1 attempt. So, I used: pip install http://projects.unbit.it/downloads/uwsgi-lts.tar.gz After doing so, I get a message prescribing the use of /usr/local/bin/uwsgi to launch the program. I'm not a guru when it comes to compiling from source, but my understanding is that when you do so, nothing will be changed in the /etc/ directory. Is this correct? If not, why don't I have a /etc/uwsgi/ directory and, more specifically, a /etc/uwsgi/apps-enabled/ directory? Should I simply create the directories when installing uWSGI from source? I was hesitant to do so, considering there is no mention of this in the docs (I don't want something that accidentally works, etc.).

• Watir changes highline's "ask" method

  - by grundic

  Hello! I've encoutered some strange functionality, when using Watir and Highline together. Here is simple example: require 'highline/import' comp = ask("Company? ") { |q| q.default = "MySuperCompany" } puts comp require 'watir' comp = ask("Company? ") { |q| q.default = "MySuperCompany" } puts comp Here is an output: Company? |MySuperCompany| MySuperCompany [Company? ] => Company? Maybe it's a bug? I've also found in documentation for highline, that If @question is set before ask() is called, parameters are ignored and that object (must be a HighLine::Question) is used to drive the process instead. Sorry, I'm not a ruby guru :-(

• SQL help - find the table that has 'somefieldId' as the primary key?

  - by Kettenbach

  Hello All, How can I search my sql database for a table that contains a field 'tiEntityId'. This field is referenced in a stored procedure, but I am unable to identify which table this id is a primary key for? Any suggestions? I currently look through stored procedure definitions for references to text by using something like this Declare @Search varchar(255) SET @Search='[10.10.100.50]' SELECT DISTINCT o.name AS Object_Name,o.type_desc FROM sys.sql_modules m INNER JOIN sys.objects o ON m.object_id=o.object_id WHERE m.definition Like '%'+@Search+'%' ORDER BY 2,1 Any SQL guru's out there know what I need to use to find the table that contains the field, 'preferably the table where that field is the Primary Key. Thanks so much for any tips. Cheers, ~ck in San Diego

• Is it secure to use malloc?

  - by Felix Guerrero

  Somebody told me that allocating with malloc is not secure anymore, I'm not a C/C++ guru but I've made some stuff with malloc and C/C++. Does anyone know about what risks I'm into? Quoting him: [..] But indeed the weak point of C/C++ it is the security, and the Achilles' heel is indeed malloc and the abuse of pointers. C/C++ it is a well known insecure language. [..] There would be few apps in what I would not recommend to continue programming with C++."

  I have a select-string which is seaching an IIS log for a particular string and returning the 2 lines above and one line below.

• FlashBuilder4 RIA on GAE

  - by user330195

  I've read/watched most of your blog/tuts and it seems you are the "beautiful front-ends for Java based back-ends" guru ;) That (sucking up ;) said, I want to build a highly scalable "facebook for business" and after much testing am pretty set on FlashBuilder4 (Flex) with Google App Engine (GAE). What are your thoughts on the need/advisability of also using Spring/Cairngorm/etc frameworks? Frankly I don't have extensive experience coding, however feel the "MVC utopia" universally aspired to becomes convoluting when duplicating between front and back ends as envisioned above (i.e. Flex/ActionScript and GAE/Java respectively).

• Any active Bold for Delphi users ?

  - by Roland Bengtsson

  What are you using as a persistance framework when programming in Delphi? If the application is growing it soon became really complicated to handle the model in SQL ? Bold is a persistance framework for Delphi win32 that really deserve more attention. I use it daily and using OCL instead of SQL to get data from the database saves a lot of time and debugging. When the model is changed Bold translate this to an SQL script and change the database. EDIT: For those that are interested in Bold for Delphi I have spend this evening on create a site on Google about it. I'm not a guru in html so the design is maybe not so exciting. But I want comments and reactions about the site. You can leave the comments in this thread or at the bottom on the subpage. And the address is... http://sites.google.com/site/boldfordelphi/

• Need help with REGEXP_REPLACE

  - by Randy

  hey regex guru's I have a data column that contains a substring similar to this: 'This is a string with ID=123 contained inside' i need to replace the ID=123 with another fixed string say ID=1 i have a working REPLACE call that swaps out the values correctly, but this only works on a known original id number. I can extend to make it work when the number of digits are known by using some substr magic, however, the id number may have an arbitrary number of digits, so i'm thinking regex. any help with the regex magix to grab the entire ID=999 substring no matter how many digits would be very helpful. thanks

• Very long tree control inside a <frame>

  - by ryancerium

  I have an tree control inside of a frame. It's quite tall, around 2000 pixels. Right now, we use the frame's scroll bars, which is mostly good. Unfortunately, when you select an item near the bottom of the list, the page reloads and the view goes back to the top of the list. I tried calling the tree control's ScrollNodeIntoView() function, but since we're not using the tree's scroll bars, it just thinks that it's displaying the full 2000 pixels and the control doesn't have its own scroll bar. I'm not much of an HTML guru, so I have two ideas, neither of which I know how to do. 1) Tell the frame to not to let the tree render all 2000 pixels and instead stay inside the viewable area. 2) Tell the tree to not render all 2000 pixels and instead stay within the viewable area. Setting the CSS height property on the within the frame doesn't do anything. Thanks.

• R: how to make a unique set of names from a vector of strings?

  - by Mike Dewar

  Hi, I have a vector of strings. Check out my vector, it's awesome: > awesome [1] "a" "b" "c" "d" "d" "e" "f" "f" I'd like to make a new vector that is the same length as awesome but where, if necessary, the strings have been uniqueified. For example, a valid output of my desired function would be > awesome.uniqueified [1] "a" "b" "c" "d.1" "d.2" "e" "f.1" "f.2" Is there an easy, R-thonic and beautiful way to do this? I should say my list in real life (it's not called awesome) contains 25000ish mircoarray probeset identifiers. I'm always nervous when I embark on writing little generic functions (which I'm sure I could do) as I'm sure some R guru has come across this problem in the past, nailed it with some incredible algorithm that doesn't even have to store more than half an element in the vector. I'm just not sure what they might have called it. Probably not uniqueify.

• Seeking free ODBC database optimization tool for non-experts

  - by mawg

  I'm a database n00b and am reading as many books as I can. I have been given responsibility for an ODBC tool where the databases were designed by a hardware engineer with some VB experience - which made him a s/w guru in the small firm at that time. Things are running slowly and I suspect that the db could have been designed better. I hope to learn enough to use Explain/Describe, etc maybe add some indices, but, in the meantime, is there any free for commercial use tool which can examine an ODBC database and suggest improvements. I'm just talking about db schema here, but maybe I should also be looking at optimizing Selects with Joins? Is there a tool for that? ODBC compliant.

• SVG Animation in Python? - Any options other than Things! 0.4?

  - by ThantiK

  I recently gave my daughter some time on the computer, and she really likes a program called 'BabySmash!', and I also have another program that came with a keyboard attachment called 'Laugh, Smile & Learn' from playschool I think. I'm not a python guru by any stretch of the imagination and I kind of have it in my head that I want to create some sort of program in the spirit of these two, with vector animation and sounds. Thing is, it doesn't look like there are many options for vector animation in python. I found a library called Things! 0.4, but it's lacking in-depth documentation and seems to be more of an experiment in vector animation rather than a full blown solution. Are there any options that I'm not immediately finding? What other animation-libraries do you recommend? Even if the library isn't vector-based, ease of use is probably the strongest factor in my use.

• Aren't passwords written in inputbox vulnerable through a stack trace ?

  - by loursonwinny

  Hello, I am not a guru of the stack tracing, at all. I even don't know how to get some. Anyway, I am wondering if entering a password entered in an inputbox is safe. Can't it be retrieved by getting a stack trace ? A password entered that way will be found in many places : Caption property of the TEdit Result of the function which creates the inputbox probably, a variable that stores the Result of the InputBox Command etc... If the answer is "yes, it is a vulnerability", then my world collapses :p. What can be done to avoid that vulnerability hole ? NOTE : The InputBox is an example but it can be with a "homebrewed" login prompt. InputBox is a Delphi command but I haven't tagged the question with the Delphi tag because I suppose that the question concerns any language. Thanks for reading

• c# Delegates, Events and Lambda Expr for new students

  - by MarkP

  I've been asked by my pointy haired boss to educate our new co-ops (interns) in the ways of C#. I have roughly ~30mins to cover the topics of Delegates, Events and Lambda Expressions. The time restriction is rather tight and the topics are broad. Since I'm not a C# guru, I would like some hints and pointers. Since my time is short, what points should I cover with respect to the three topics listed above? What are some good Do's and Dont's when using those three things? I might have time for a short Lambda Expr demo. What is the most common use of LExpr (probably a Select().Where() statement on an enumerable??) that I could demo? Thanks. EDIT: The students have working knowledge of C++ and Java.

• Web Application - Authentication / Login Framework

  - by user456563

  This is a very simple, probably a most asked question and frequently developed as part of any web application. Say I'm planning to build a web application and some of the functional requirements include (apart from the usual hard hitting security reqs), - Need to have users sign up for a new account profile - Authenticate user using the native app authentication / Facebook or Google or Yahoo or OpenId login - Allow lost password retrieval - Session handling needs Is there an out of the box frameworks (Drupal, Liferay??) that I can use to wrap my application which can be a bunch of JSP's or HTML's with JS? I know I'm asking a very simple and maybe a naive question. But this is a topic every web developer guru will go thru. Any help, advise and pointers much appreciated.

• Need CSS Help with a hover element - cant extend to left and right of page

  - by Bobafett

  Hi there, Need some CSS guru help. If you visit my link: http://www.gabbr.com/js/viewer/cmedata/index1.html and hover over the years (top middles, 2008, 2009, 2010, etc) you will notice an orange bar extending from the top to the bottom of the page. I am trying to get the same effect on the left (month and day) but am unable to do so. The problem I am having is that I cannot get the orange hover bar to extend off the left of the screen for either #dayleft or for #monthleft. It extends all the way to the right margin of the screen but not the left. The problem is the margin-left: 15px; in #monthleft and margin-left: 80px; in #dayleft. But I cannot get rid of these since I require them for the letter spacing. Any advice?

• what are most important things that i must know in order to jump into silverlight development

  - by Poni

  I have vast programming knowledge; C++/C#/ActionScript/ASM/PHP..... so learning the language of SilverLight itself isn't of an issue. To keep long story short, when asking this question I'm asking it as a developer who's coming from Flash world - great graphics/sounds/media support, fully cross-platform, ability to combine several SWFs within a "movie" (which also implies code reusability). A Flash developer have pretty much freedom. What are most important things that i must know in order to jump into silverlight development? Did you already make the move to SilverLight from Flash yourself? Are you a "guru" at both? Great, let's hear what you have to say - developer to developer! =)

• Building ffmpeg with an executable output

  - by Kevin Galligan

  I generally don't like to ask such "you figure it out for me" questions, but I suspect this one will be really simple for a C++ guru. I want to build ffmpeg for Android, and I'd like it to output an executable rather than a set of libraries. We've been using the guardian project's build: https://github.com/guardianproject/android-ffmpeg It does produce what we want, but I've found tweaking it for different architectures to be, at best, unpleasant. I've gotten this version to build: https://github.com/appunite/AndroidFFmpeg It does a nice job of slicing and dicing different architectures, but produces a jni version. There is a long story as to why I want the exe, but I'll skip it for now. Is there a flag that needs to be flipped? Some path or other setting? I am at this point fully baffled. Thanks in advance.

• SQL update statement to change the value of a field and not replace it

  - by wzzrd

  I'm in the process of migrating some databases. I have this table that has a couple of hundred rows, and has a filename column. To each record in this table, the filename column needs to be altered and part of a path needs to be prepended to the value that is in that field. The table is like: | 1 | filename1 | | 2 | filename2 | and needs to become: | 1 | path/filename1 | | 2 | path/filename2 | I am not an SQL guru, but I know the basics. This eludes me though. Is there a way to do something like: update table set filename = 'path/' + filename where id = 1;
