Format NSString to left pad zeroes in Objective C

01, 02, 03, 04, 05..

int num = 1;
[NSString stringWithFormat:@"%02d", num];

001, 002, 003, 004, 005..

[NSString stringWithFormat:@"%03d", num];

0001, 0002, 0003, 0004, 0005..

[NSString stringWithFormat:@"%04d", num];

You get the pattern? Good!

Anywhere Pad, the Board Portal Software for iPads and Android Tablets

Around a year ago, I wrote about Anywhere Pad, particularly about its new design. That blog entry was more of a test than anything else, but I thought of doing a follow-up post because a lot has happened since I published the first one.

Yes, I'm still affiliated with the product, but I can say with only a tiny hint of bias that Anywhere Pad has significantly improved from the first time I featured it here. 

Aside from the continuous enhancements we've been adding to refine Anywhere Pad's usability, we also made it more streamlined by aligning the Android version with the iOS version. Our goal is to give directors and administrators the same user experience whether they're using an iPad or Android tablet. It's not enough that Anywhere Pad works on Android and iOS. We want it to work just as well for either platform so whatever you choose, you get to enjoy all the benefits and conveniences offered by Anywhere Pad.

This move is in response to the fact that many organizations are now adopting a Bring Your Own Device (BYOD) policy. We realize the policy won't be effective unless people have the freedom to choose whatever device to use; but with most board portal vendors offering board portal solutions for iPad use only, administrators and directors have no choice but to switch to iOS tablets if they aren't already using one yet. Don't get me wrong – iPads are great gadgets. But there are a lot of folks who prefer to use Android devices (which are great gadgets, too) so it only makes sense that they get choice in the matter as well.

Thus, we made Anywhere Pad a viable Android board portal solution for enterprise use. With stringent security features such as AES-256 network encryption, AES-128 document encryption, 2048-bit SSL, ISO 27001 (AWS EC2), on-the-fly decryption, automatic purge for lost devices, audit logging, and fine-grained access control, Anywhere Pad can effectively safeguard confidential information from malicious attacks and unauthorized access, whether the threat is internal or external.

Aside from security, we also beefed up the real-paper feel directors have been looking for in a board portal solution. The freehand annotation feature allows users to write comments using their own hand or stylus, while the whiteboard lets them draw diagrams (and even doodles) and map out processes.

[Solved] Error in npm install from a github url

If you're like me who's used to executing "git clone [github url]" then you may encounter an unusual behavior when using "npm install [github url]" or specifying the git repository inside package.json.

Here's a sample error of using npm install [github path]:

E:\progs\workspace\tmp>npm install https://github.com/mannyvergel/oils-js.git

The solution is very simple, just prefix your github url with "git+" e.g.

git+https://github.com/mannyvergel/oils-js.git

Use the format in your package.json or npm install, e.g.

npm install git+https://github.com/mannyvergel/oils-js.git

[Solved] NodeUnit does not finish when connected to Mongo DB

When running NodeUnit tests and your tests are connected to Mongo DB, the tests do not end and it just hangs there. The fix is to close the connection on NodeUnit's tearDown function.

Example below is using Mongoose' disconnect function to close the connection after NodeUnit tests are done:

var mongoose = require('mongoose');
exports.tearDown = function(ok){
    mongoose.disconnect(function(err){
        if(err) {
            console.error(err);
            return;
        }
    });
    ok();
};

How to create and apply a patch from an SVN Commit

In subversion, there are cases that you may want to apply the same commit to another folder. E.g. you have a similar branch of your source code and you have committed the changes in your main branch. For this case, rather than copying your codes manually, you can create a patch from your SVN commit and apply it to another directory using the ff:

Create a patch from your commit, get the difference between two svn commits. Usually it's just your [desired commit #] minus one:

svn diff -r [reference commit]:[desired commit] > [filename]

e.g.

svn diff -r 9714:9715 > 9715.patch

Copy the patch file to the directory you want to apply it and go to that directory in the command line and type:

patch -p0 < [filename]

e.g.

patch -p0 < 9715.patch 

[Solved] 403 Status Code on Twitter API

As of January 14, I was surprised to see that my code that uses Twitter API to post tweets does not work anymore. Then I saw the announcement that they now require https for all connections, so my change is quite simple:

From:

http://api.twitter.com/1.1/statuses/update.json

To:

Path to iPhone Simulator files in Mac OS X Mavericks, Xcode 5

You should start looking in:

/Users/[current user]/Library/iPhone Simulator/

If you can't see the Library folder in Finder, click here how to show hidden files and folders in Mac OS X.

To access the applications in the Simulator, pick the iOS version you are using e.g.:

/Users/[current user]/Library/iPhone Simulator/6.1

Go to Applications folder and pick the hashed folder name that contains your application e.g.

/Users/[current user]/Library/iPhone Simulator/6.1/Applications/2ABAAFD5-71B0-478A-BEBD-13BA56AA03D7

For the SQLite Database, it should be inside the "Documents" folder with the extension ".sqlite" e.g.:

/Users/[current user]/Library/iPhone Simulator/6.1/Applications/2ABAAFD5-71B0-478A-BEBD-13BA56AA03D7/Documents/myapp.sqlite

You can use Liya app (it's free) to open the sqlite database.
