  • How does Symfony pass members set in an action to a template?

    - by Martin Chatterton
    How does a member set inside an action... $this->foo = 'bar'; ...become a variable accessible from a template... echo $foo; // bar I would like to know how it is achieved at a framework level. There is a lot of documentation on how to use Symfony, but I've not managed to find much about how it all fits together behind the scenes (class structure/inheritance etc). Thanks in advance for your help!

  • Can you make a living as a system programmer?

    - by Helper Method
    Is there still a market for C system programmers? I love Java and some of the newer JVM languages but at the same time I really enjoy low-level system programming under Unix, using C and the GNU toolchain (it makes you feel elitist ;-)). Now I wonder a) is there still a market for C system programmers and b) how much do you earn compared to an app programmer c) is it that much fun in a large scale project?

  • Table for each region in MySQL

    - by King Wu
    There are four regions with more than one million records total. Should I create a table with a region column or a table for each region and combine them to get the top ranks? If I combine all four regions, none of my columns will be unique so I will need to also add an id column for my primary key. Otherwise, name, accountId & characterId would be candidate keys or should I just add an id column anyways. Table: ---------------------------------------------------------------- | name | accountId | iconId | level | characterId | updateDate | ----------------------------------------------------------------

  • Sorting string column containing numbers in SQL?

    - by Ish
    Dear Folks, I am trying to sort string column (containing numbers). // SELECT `name` FROM `mytable` ORDER BY `name` ASC +----------+ +-- name --+ +----------+ +-- a 1 ---+ +-- a 12 --+ +-- a 2 ---+ +-- a 3 ---+ You see natural sorting algorithm of Mysql is placing a 12 after a 1 (which is ok for most apps), But I have unique needs, so I want result should be sorted like this. +----------+ +-- name --+ +----------+ +-- a 1 ---+ +-- a 2 ---+ +-- a 3 ---+ +-- a 12 --+ Is it possible with just SQL, or I have to manipulate result-set at application level? Thanks for reading...

  • What's wrong with this function?

    - by ct2k7
    Hello, I'm using this function to determine whether my application should be online or offline: function online() { if ($online == "0") { if($_SESSION['exp_user']['userlevel'] != "1") { include("error/offline.php"); exit(); } } } However, with the data value set to 0 in the database, and $online does = '0', why is error/offline.php not included for those whoose user level is not 1? Thanks :)

  • How to suppress warnings in external headers in Visual C++

    - by Bob Whiteman
    I'm starting a new BREW project, and I'd like to compile with Warning Level 4 (/W4) to keep the application code nice and clean. The problem is that the BREW headers themselves don't compile cleanly with /W4. In gcc you can differentiate between application and system headers by using -I and -isystem, and then by default gcc doesn't report any compilation warnings in system headers. Is there an equivalent mechanism in Visual C++?

  • RESTfully request sub-parts of a representation be of a certain content-type

    - by Grayside
    I am requesting (via Accept: application/json) that an API I'm designing respond as JSON. However, I want the values within that JSON to be specified to conform to text/plain or text/html depending on the capabilities of the client. What is the RESTful best practice for a "sub-type"? How would this work if I formally switched to HAL as the top-level container? Accept: application/json+text/plain { "value": "Hello World" } Accept: application/json+text/html { "value": "<h2>Hello World</h2>" }

  • Is it okay to mix session data with form and querystring values in a custom model binder?

    - by Byron Sommardahl
    Working on a custom model binder in ASP.NET MVC 2. Most of the time I am binding data from typical form or querystring data. There are times that I end up letting the model binder bind part of an object and get the rest out of session at the controller action level. Does it make better sense to bind the entire object from the model binder (e.g. querystring, form, and session)?

  • Why is C++ backward compatible with C ? Why isn't there some "pure" C++ language ?

    - by gokoon
    C and C++ are different languages, blababla we know that. But if those language are different, why is it still possible to use function like malloc or free ? I'm sure there are all sort of dusty things C++ has because of C, but since C++ is another language, why not remove those things to make it a little less bloat and more clean and clear ? Is it because it allows programmers to work without the OO model or because some compilers doesn't support high-level abstract features of C++ ?

  • Should I merge .pbxproj files with git using merge=union?

    - by Ortwin Gentz
    I'm wondering whether the merge=union option in .gitattributes makes sense for .pbxproj files. The manpage states for this option: Run 3-way file level merge for text files, but take lines from both versions, instead of leaving conflict markers. This tends to leave the added lines in the resulting file in random order and the user should verify the result. Normally, this should be fine for the 90% case of adding files to the project. Does anybody have experience with this?

  • selecting files in windows-7 explorer just by hovering

    - by bortao
    One of the biggest annoyances for me of Windows 7 vs Windows XP is that you cant select files properly by hovering over them on Windows Explorer (or multi select by holding ctrl). When i hover an item it gets light blue, not selected. Only after a time or after more hovering, it gets selected. I set the delay (MouseHoverTime) to 1. Windows seems to avoid wrong selection by requiring an additional time or space of mouse hovering before actually selecting the item. I tried playing with the values MouseHoverHeight, MouseHoverWidth, MouseSensitivity, MouseThreshold1 and MouseThreshold2 in HKEY_CURRENT_USER\Control Panel\Mouse, but they seem to have no effect over this. (they are currently on (20, 20, 16, 6, 10, respectively). What i want: to immediately select an item whenever the mouse gets over its bounds.

  • Cassandra replication system - how it works

    - by inquisitor
    Does cassandra replicates only on write procedure (with choosen consistency level)? Is there any auto-replicate option for absent nodes, if i want symetric data in every node? If I plug in new node to cluster there is no auto replication - how to sync data from others nodes with new one? If I want replication like multimaster (2 nodes) with slave backup (1 node) known from MySQL, what is the proper logic setup and manage that on cassandra (3 nodes)? How about two nodes?

  • Variable scope and the 'using' statement in .NET

    - by pete the pagan-gerbil
    If a variable is at class level (ie, private MyDataAccessClass _dataAccess;, can it be used as part of a using statement within the methods of that class to dispose of it correctly? Is it wise to use this method, or is it better to always declare a new variable with a using statement (ie, using (MyDataAccessClass dataAccess = new MyDataAccessClass()) instead of using (_dataAccess = new MyDataAccessClass()))?

  • How do I prevent 'net ads join' from doing DDNS update?

    - by genehack
    I'm using 'net ads join' to add Linux servers to an AD domain. The servers are multi-homed, with a public IP on eth1 and a non-routable private background network on eth0 (in the 172.20 space, used for netboots and installs and stuff -- no routing to the Internet on that network). When I 'net ads join', it appears that a DDNS entry is getting created for the 172.20 interface. How can I prevent this from happening? (FWIW, my powers at the AD level are very limited -- I can join servers and delete server records but that's about it...)

  • Linux C++: how to profile time wasted due to cache misses?

    - by anon
    I know that I can use gprof to benchmark my code. However, I have this problem -- I have a smart pointer that has an extra level of indirection (think of it as a proxy object). As a result, I have this extra layer that effects pretty much all functions, and screws with caching. Is there a way to measure the time my CPU wastes due to cache misses? Thanks!

  • Why is my email server in AT&T's blacklist?

    - by legoscia
    I just got this bounce message: <¦¦¦¦¦¦¦¦@att.net>: host scc-mailrelay.att.net[204.127.208.75] said: 521-88.208.246.34 blocked by sbc:blacklist.mailrelay.att.net. 521 DNSRBL: Blocked for abuse. See http://att.net/blocks (in reply to MAIL FROM command) So I'm trying to figure out why our server ended up on their blacklist. The web page link doesn't tell me why, as far as I can see. From a few multi-RBL tools I conclude that our IP is only on the collateral damage lists of uceprotect.net (you can be exempt from that with a paid subscription), and I dearly hope that AT&T doesn't use that. From the mail server logs I see that an email to another @att.net address went through two days ago without being blocked. Does anyone have any ideas how I can find out what went wrong?
