Google App Engine, Secure Data Connector (SCD), and supported protocols

- by Pablo Alvim

I've been investigating what I can do with Google's Secure Data Connector and App Engine. Is it possible, from an App Engine application, to grab resources inside my corporate intranet without using HTTP(S)? From what I read in the documentation, the only way to request resources through SDC is by using url_fetch, which is limited to HTTP, right?

I'm sending a JSON response from php to jquery: foreach ( $obj as $o ) { $a[ $o->key] = utf8_encode($o->id); } die(json_encode($a)); my html/jquery code is: $.ajax({ type:'POST', url: "imoveis/carrega_bairros", data: ({cidade:10}), dataType:"json", success: function(ret) { alert(ret) if(ret.success) { // ... } else alert("error"); } }); The json response is perfect (i get it on the console), but jquery is receiving a NULL ret object and it alerts "error". What's the problem???

Good ways to map a 2D side shooter (somewhat like liero, or soldat)

- by Blaze

I'm wondering what way would be best to render a 2D map for a shooter (these will be static maps) similar to Soldat. Multiple options I've considered are a tile based map (stored in txt files), or just creating different classes for the different terrains I plan to use and creating a data structure to read/store them in a file. (I want to also be able to include things like jumping/running on walls, sliding down walls/slopes ect) I feel like there must be a better way than either of these, but haven't been able to find definitive information :/ Thanks :)

Determine from where is "sh" being run under apache www-data user using using PF or NETSTAT

- by Eugene van der Merwe

I am working with a compromised Ubuntu 8.04 Plesk 9.5.4 server. It seems that a script on the server is continuously doing reverse lookups to random IPs on the Internet. I first spotted it during by using top and then noticed flashes of this coming up continuously: sh -c host -W 1 '198.204.241.10' I wrote a this script to interrogate ps every 1 second to see how frequently this script happens: #!/bin/bash while : do ps -ef | egrep -i "sh -c host" sleep 1 done The results are that this script runs often, every few seconds: www-data 17762 8332 1 10:07 ? 00:00:00 sh -c host -W 1 '59.58.139.134' www-data 17772 8332 1 10:07 ? 00:00:00 sh -c host -W 1 '59.58.139.134' www-data 17879 17869 0 10:07 ? 00:00:00 sh -c host -W 1 '198.204.241.10' www-data 17879 17869 1 10:07 ? 00:00:00 sh -c host -W 1 '198.204.241.10' www-data 17879 17869 0 10:07 ? 00:00:00 sh -c host -W 1 '198.204.241.10' root 18031 17756 0 10:07 pts/2 00:00:00 egrep -i sh -c host www-data 18078 16704 0 10:07 ? 00:00:00 sh -c host -W 1 '59.58.139.134' www-data 18125 17996 0 10:07 ? 00:00:00 sh -c host -W 1 '91.124.51.65' root 18131 17756 0 10:07 pts/2 00:00:00 egrep -i sh -c host www-data 18137 17869 0 10:07 ? 00:00:00 sh -c host -W 1 '198.204.241.10' www-data 18137 17869 1 10:07 ? 00:00:00 sh -c host -W 1 '198.204.241.10' My theory is if I can see who is launching the sh process or form where it's launched I can isolate the problem further. Can somebody please guide me using netstat or ps to identify from where sh is being run? I might get many suggestions that the OS is out of date and so the Plesk, but please bear in mind there are some very concrete reasons why this server is running legacy software. My question is aimed at a advanced Linux systems administrators who have in depth experience with security compromises and using netstat and ps to get to the bottom of it.

Automatic Data sorting/ analysis in Excel

- by hkf

I have data in the form of four columns. The first three columns represent time, value1, value 2. The fourth column is binary, all 0's or 1's. Is there a way to tell excel to delete time, value1 and value 2, when the corresponding binary value in column four is 0? I know this is a lot easier in C++ or matlab, but for reasons beyond my control, I must do it in excel.

Best practices and Design Patterns for iPhone forms?

- by cannyboy

Part of the app I'm making requires the user to fill in a multi-page form, the contents of which will be saved locally (perhaps using Core Data). Are there any best practices for this? This form just includes text fields. I guess the options are UITextFields, or perhaps a UIWebView, with the fields as part of an html form? Are there are any best practices, or design patterns, which are good for this kind of thing?

Best way to model Customer <--> Address

- by Jen

Every Customer has a physical address and an optional mailing address. What is your preferred way to model this? Option 1. Customer has foreign key to Address Customer (id, phys_address_id, mail_address_id) Address (id, street, city, etc.) Option 2. Customer has one-to-many relationship to Address, which contains a field to describe the address type Customer (id) Address (id, customer_id, address_type, street, city, etc.) Option 3. Address information is de-normalized and stored in Customer Customer (id, phys_street, phys_city, etc. mail_street, mail_city, etc.) One of my overriding goals is to simplify the object-relational mappings, so I'm leaning towards the first approach. What are your thoughts?

Handling of data truncation in FUSE

- by Vi

I expect any good program should do all their reads and writes in a loop until all data written/read without relying that write will write everything (even with regular files). Am I right? Implemented simple FUSE filesystem which only allows reading and writing with small buffers, very often returning that it is written less bytes that in a buffer (using -o direct_io). Some programs work, some not. Are them buggy or programs should not expect truncated writes and reads from the regular files?
