Twitter API JSON - Returning wrong ID of tweets

Twitter recently updated its API to enable the new Status ID generator - 'Snowflake'. With that, the new unique Tweet IDs are now 64bit unsigned integers, which, instead of being sequential like the old IDs, are based on time. The full ID is composed of a timestamp, a worker number, and a sequence number.

The implications of this change is that some programming languages like Javascript cannot support numbers with >53bits. To allow javascript and JSON parsers to read the IDs, a string version of any ID is now included when responding in the JSON format. What this means is Status, User, Direct Message and Saved Search IDs in the Twitter API will now be returned as an integer and a string in JSON responses. This will apply to the main Twitter API, the Streaming API and the Search API.

For example, https://twitter.com/status/user_timeline/hongjun.json?count=5 now returns you both "id" and "id_str". We should now be using "id_str" instead.

The following code in complete will display tweets using JSON method.

How to stop FortiClient from starting automatically?

Installed FortiClient recently but the challenge in disabling the application/service from running automatically on every start-up annoyed me. Attempt to stop 'FortiClient Service Scheduler' only return 'Parameter is incorrect' error message.

An article on Technet help solve my trouble. To stop FortiClient from starting automatically, try the following:
Shut down FortiClient from the system tray.
Run net stop fortishield on command prompt.
Run msconfig.
On msconfig, switch to the Services tab. Clear the FortiClient Service Scheduler check box and click Apply.Run services.msc on command prompt to open up show all available services.Look for FortiClient Service Scheduler. Switch Startup type to Manual.Restart your computer. FortiClient should not be running automatically the next time round. Hope it helps.

ACJC Birthday Girl Tied Up and Tortured

The two videos mentioned are particularly shocking to me because of two factors. First of all, the perpetrators are practically all females, with a few boys in the background cheering. I never knew women are into such cruelty as well. Second, it occurred in bright daylight at a crowded school canteen - where everybody can see! The poor victim was tied to a chin-up bar and attacked mercilessly. All in the name of “celebrating” her birthday.

The school where all these took place is a well-reputed school - Anglo-Chinese Junior College (ACJC). (No point in concealing the school’s identity as the uniform of the students involved is obvious).

Video captured on the incident was uploaded onto YouTube but was taken down after this matter was blown up.
