• Optimizing data downloaded via 'link' media queries and asynchronous loading

  - by adam-asdf

  I have a website that tries to make sensible use of media queries and avoid 'expensive' CSS for users of mobile devices. My eventual goal is to make it 'mobile-first' but for now, since it is based on Twitter Bootstrap it isn't. I included some background images (Base64 encoded) and styles that would only apply to "full-size" browsers in a separate stylesheet loaded asynchronously via modernizr.load. In Firefox (but not webkit browsers) it makes it so that if you navigate away from the homepage and then return, the content (specifically, all those extras) 'blinks' when it finishes loading...or maybe I should say reloading. If, instead of using modernizr.load, I include that stylesheet via a link... in the head with a media query attribute will it prevent the data from being downloaded by non-matching browsers (mobile, based on screensize) that it is inapplicable to?

• creating object parameters in {}?

  - by RealityDysfunction

  I am trying to decode a piece of code from a book: List<Person> people = new List<Person>() { new Person {FirstName="Homer",LastName="Simpson",Age=47}, new Person {FirstName="Marge",LastName="Simpson",Age=45} }; Person is just a simple class they made, with a bunch of fields: Name, Last Name, etc... What I don't understand is, don't we send parameters to a constructor of Person in non-curly brackets? I tried replicating this code, but it doesn't seem to fly, any takers? Thanks for input.

• Quantitfying a cost for a software project

  - by The Elite Gentleman

  Disclaimer: I didn't know exactly where to put this question. If you feel that this question is not suitable for Programmers @ StackExchange, feel free to migrate it. Background: Broadening my last question, there is a request for tender for a software system that's open and I have decided to take it on. I am a software developer & engineer by profession and, in this tender process, I have to put on the pricing for my bid. I have been provided a documentation consisting of functional and non-functional requirements only. I have to put a project manager's cap on and think of all aspects, e.g. cost for implementation for the project, resources needed, etc. My question is: Is there a project framework that I can follow that breaks the project cycle into steps and corresponding cost aspect or how would I go about best calculating/approximating the cost for the project?

• Constructive ways to answer "What was your most challenging project? and why?"

  - by tau

  I am asked this question many times in the interviews. What was your most challenging project -- and why? I get confused about which project to tell them and why some project would look challenging or non-challenging. What are they looking for in the answer? Any software is a challenge before it gets started and it becomes a normal software engineering task after it has finished. All softwares I made were challenging until they got finished. Do I misunderstood the word "challenge"? What's wrong in my thinking? What's an appropriate and constructive way to approach this question?

• L'iPhone 4G dévoilé par une fuite, Apple exige la restitution de l'appareil

  L'iPhone 4G dévoilé par une fuite, Apple exige la restitution de l'appareil Voici comment un secret si bien gardé jusqu'alors s'est retrouvé à faire le tour du Web ... Un simple oubli a suffit à gâcher le grand événement que constitue d'habitude l'annonce d'un produit Apple : l'iPhone 4G devait être annoncé en juin, avant qu'un ingénieur de chez Apple ne l'oublie dans un bar près du siège... Le jeune homme aurait utilisé ce nouvel iPhone alors qu'il fêtait le 18 mars son 27ème anniversaire au «Gourmet Haus Staudt», un bar de Redwood City, non loin du siège californien d'Apple.

• Microsoft gives you your cache back

  - by Dave Ballantyne

  The system works and its called Microsoft Connect , who would of thought it :) Following on from my previous blog post MicroSoft – Follow best practices, on the connect item , the followup stated that changes had been made in 2008.  I genuinely thought that a change would take an age to trickle through to the customer. But after firing up 2008R2 RTM and examining the SqlAgent traffic with profiler , where before i would see non-parameterized sql, I now see RPC calls.    Excellent , i get my cache back.

• Querying Literals in Entity SQL

  Entity SQL might surprise you if you are building query expressions with some non-string types. Ive blogged about this before with the DateTime literal after trying to use a string to represent the date in my query as Im used to with TSQL.

• What is So Unique About Node.js?

  - by Adrian Shum

  Recently there has been a lot of praise for Node.js. I am not a developer that has had much exposure to network application. From my bare understanding of Nodes.js, its strength is: we have only one thread handling multiple connections, providing an event-based architecture. However, for example in Java, I can create only one thread using NIO/AIO (which is non-blocking APIs from my bare understanding), and handle multiple connections using that thread, and I provide an event-based architecture to implement the data handling logic (shouldn't be that difficult by providing some callback etc) ? Given JVM being a even more mature VM than V8 (I expect it to run faster too), and event-based handling architecture seems to be something not difficult to create, I am not sure why Node.js is attracting so much attention. Did I miss some important points?

• Setting TeX Live path for root

  - by N.N.

  I have installed TeX Live 2011 vanilla and I have trouble setting the TeX Live path for root (in Ubuntu 11.10). The problem is that when I run sudo tlmgr I get: sudo: tlmgr: command not found To fix the path for non-root it was sufficient to add PATH=/usr/local/texlive/2011/bin/x86_64-linux:$PATH to /etc/profile. I have tried adding this same line to /root/.bashrc and I have also tried to add it to /etc/profile.d/zzz-texlive.sh like Herbert suggest in http://tex.stackexchange.com/questions/26624/tlmgr-inaccessible/26626#26626 but it does not help.

• Is it possible to preview arbitrary formats in Nautilus?

  - by alfC

  I recently found out that Nautilus (Ubuntu 12.04 at least) can show thumbnails of files of non-image formats, for example (data grapher) grace files (.agr) shows a small version of the graph contained in its data. Obviously, there some library or script that is processing the file, making the image, and allowing nautilus to show a small version of it. This made me think that in principle any file that potentially can be processed into an image can serve as a Nautilus thumbnail. For example, a .tex file (which can be converted to .pdf) or a gnuplot script can be displayed as a thumbnail when possible. In the case of .tex file, the correspoding .pdf can be created by the command pdflatex file.tex. The question is, how can I tell Nautilus to create a thumbnail for an arbitrary format and how do I specify the commands to do so within Nautilus?

• Optimal Database design regarding functionality of letting user share posts by other users

  - by codecool

  I want to implement functionality which let user share posts by other users similar to what Facebook and Google+ share button and twitter retweet. There are 2 choices: 1) I create duplicate copy of the post and have a column which keeps track of the original post id and makes clear this is a shared post. 2) I have a separate table shared post where I save the post id which is a foreign key to post id in post table. Talking in terms of programming basically I keep pointer to the original post in a separate table and when need to get post posted by user and also shared ones I do a left join on post and shared post table Post(post_id(PK), post_content, posted_by) SharedPost(post_id(FK to Post.post_id), sharing_user, sharedfrom(in case someone shares from non owners profile)) I am in favour of second choice but wanted to know the advice of experts out there? One thing more posts on my webapp will be more on the lines of facebook size not tweet size.

• Should I limit my type name suffix vocabulary when using OOP?

  - by Den

  My co-workers tend to think that it is better to limit non-domain type suffixes to a small fixed set of OOP-pattern inspired words, e.g.: *Service *Repository *Factory *Manager *Provider I believe there is no reason to not extend that set with more names, e.g. (some "translation" to the previous vocabulary is given in brackets): *Distributor (= *DistributionManager or *SendingService) *Generator *Browser (= *ReadonlyRepositoryService) *Processor *Manipulator (= *StateMachineManager) *Enricher (= *EnrichmentService) (*) denotes some domain word, e.g. "Order", "Student", "Item" etc. The domain is probably not complex enough to use specialized approaches such as DDD which could drive the naming.

• Screenshot Tour: 10 New Features in Android 4.2 Jelly Bean

  - by Chris Hoffman

  Android 4.2 improves on Android 4.1 in numerous ways, adding a variety of new features. Android 4.2 isn’t as big an update as Android 4.1, also called Jelly Bean, but it’s a definite improvement. If you have a Nexus 7 or Galaxy Nexus, you should be getting this update very soon. Unfortunately, it will likely take quite a bit longer for manufacturers to ship Android 4.2 on non-Nexus devices.

• Web Usage Policies at "Best Companies to Work For"

  - by Greg

  For any company that has made it onto a "Best Companies to Work For" list* in 2010 that hires programmers, what restrictions on web usage do they have in place? Does that company view unrestricted internet access as a benefit to their employees even if they might use it for non-work related reasons? If you can provide a link to back up this information, even better. (* I don't want to promote any specific publication, but they are easy enough to find.) My hypothesis is that a company that aspires to be one of the best needs to provide fairly unrestricted internet access and I'm trying to test it.

• Managing Custom Series

  - by user702295

  Custom series that have been added should be done with client Defined Prefix, ex. ACME Final Forecast, so they are can be identified as non-standard series.  With that said, it is not always done, so beginning in v7.3.0 there is a new column called Application_Id in the Computed_Fields table.  This is the table that stores the Series information.  Standard Series will have have a prefix similar to COMPUTED_FIELD, while a custom series will have an Application_Id value similar to 9041128B99FC454DB8E8A289E5E8F0C5. So a SQL that will return the list of custom series in your database might look something like this: select computed_title Series_Name, application_id from computed_fields where application_id not like '%COMPUTED_FIELD%' order by 1;

• Why is Cocoa using an old version of Unicode? [closed]

  - by Randy Marsh

  While I was searching for something in the Apple docs, I stumble on this: illegalCharacterSet Returns a character set containing values in the category of Non-Characters or that have not yet been defined in version 3.2 of the Unicode standard. On the Unicode website, I find that the latest version is 6.1.0. That's a lot of major versions higher than what Cocoa supports. Does somebody know why Apple doesn't upgrade their framework? My more important question is: Are there problems for not doing having support for Unicode 3.2+? Will I have problems reading Unicode files created on other systems with a more recent version of Unicode?

• Oracle Communications Calendar Server: Upgrading to Version 7 Update 3

  - by joesciallo

  It's been some time since I have posted an entry. Now, with the release of Oracle Communications Calendar Server 7 Update 3, it seems high time to jump start this blog again. To begin with, check out what's new in this release: Authenticating Against an External Directory Booking Window for Calendars Changes to the davadmin Command Enable and Disable Account Autocreation LDAP Pools New Configuration Parameters New Languages New populate-davuniqueid Utility New Schema Objects Non-active Calendar Accounts Are No Longer Searched or Fetched Remote Document Store Authentication The upgrade is a bit more complicated than normal, as you must first apply some new schema elements to your Directory Server(s). To do so, you need to get the comm_dssetup 6.4 patch, patch the comm_dssetup script, and then run the patched comm_dssetup against your Directory Server(s) instances. In addition, if you are using the nsUniqueId attribute as your deployment's unique identifier, you'll want to change that to the new davUniqueId attribute. Consult the Upgrade Procedure for details, as well as DaBrain's blog, before forging ahead with this upgrade.

• Ubuntu install and boot failure 11.10

  - by Robert Moody

  I installed Ubuntu 11.10 on my machine alongside Vista, and upgraded to 12.4. I decided I liked 11.10 better, so I tried to install that again as my only OS, except I increased the size of the swap file partition to 2 gigs. It boots up fine off the CD, but when I install, it gives me a non-specific error, and returns me to the desktop. When attempting to boot off the hard drive, I get a black screen with a blinking underscore that starts in the corner, drops a couple spaces, and stays there. I managed to install 9.04, and am currently using that. The computer is a little outdated, but was fired up for the very first time last week, so the hard drive is in new condition and the CD rom drive is fine too. Running a 3GHzX2 processor. I ran a memory test, which came back fine, and being new to the linux environment, I've been scratching my head for the last couple days. How can I fix this?

• Setting APPMENU_DISPLAY_BOTH for gnome applications does not work on Ubuntu 12.04 LTS

  - by Jack'

  To start the application with the menu enabled in the application and the panel, the following command has to be used: APPMENU_DISPLAY_BOTH=1 appname I recently discovered that this only works for non-gnome applications on Ubuntu 12.04 LTS, i.e. if you replace appname with applications such as gnome-terminal, gedit, evince, empathy, evolution, rhythmbox, nautilus, etc. only global menus will be displayed. However, if you start, for example, gimp or inkscape by using APPMENU_DISPLAY_BOTH, both global and local menus will be shown. The questions is: why is APPMENU_DISPLAY_BOTH not taken into account when starting such gnome applications? P.S. I know how to disable global menus in order to get the local ones (UBUNTU_MENUPROXY trick, removing appmenu-gtk/qt packages, removing the indicator-appmenu, etc.) Thanks for the help!

• If I release a program under GPL, do I have to continue to do so?

  - by Kos

  Consider this scenario: I am developing a program FooSuite that uses a GPL-licenced library QuuxTools I release the program FooSuite 1.0 under GPL Later on I discover that, for some reason, I need to licence the program to someone on different terms. Hence: I remove the dependency on GPL via QuuxTools, by either... rewriting the program not to use this library any longer obtaining a different licence for QuuxTools (if it's dual-licenced; see PyQt) I release FooSuite 1.1 under a non-GPL licence. However, FooSuite 1.1 is still a derivative work from FooSuite 1.0. I understand that it's not legal for a stranger to do what I did, but am I myself - as the owner of FooSuite - free from this restriction?
