VPN Enabler 1.0.1
Category : Technology/VPNEnabler1dot0dot1.txt
I’ve updated VPN Enabler to make it more helpful. I’ve added a “Suggest IP Addresses” button. (Download VPN Enabler 1.0.1
If you’re running VPN Enabler on the single machine, on the local network behind the router, that has all the Internet services loaded on it (e.g., web, mail, and dns server, all on one machine, which is quite a reasonable assumption for the user base that is running all my “enabler” apps), then when you click on that “Suggest IP Addresses” button, it’ll try to provide you with reasonable values that you can use.
These values are provided to an incoming VPN client, which is joining your private local network, so it’ll firstly be assigned an IP address within the range you provided, and then it’s told where to go for DNS services. Basically, the VPN Server acts like a DHCP Server for the incoming VPN clients.
Let a Thousand VPN Servers Bloom
Category : Technology/VPNEnabler.txt
I’m releasing Version 1.0 of VPN Enabler (this is the download link
). I used this to set up a VPN Server on OS X Mavericks before I went to China, so I can access Facebook, etc, while I was on wifi networks in Chengdu, Sichuan. As far as I can test myself, the VPN Server works (wonderfully, if I may add :)
Only three steps and one click. That’s all it takes to get your own VPN Server running. Of course, your Mac server must be accessible from the Internet. If you’re on a dynamic IP address, sign up with DNS providers like dyndns.org, and use my app, DNS Agent
(for Mavericks), to keep your IP address in sync with your domain name, no matter how often that changes.
On the Mac client, set up your VPN configuration like this, in Network Preferences :
Click the Authentication Settings… button:
And click the Advanced… button to set the “Send all traffic over VPN connection” option:
For iOS clients, look for Settings > General > VPN. Add a VPN Configuration:
and, in the Add Configuration panel, do this:
And that’s all there is to it. Enjoy!

I’ve got a VPN Server running on the plain client version of Mavericks. As usual with these installations, I did so many things to get this to work. I’ll need to figure out what I did that actually worked, and then put them all into a “VPN Enabler” app.
There are many uses for a VPN server. I’ll be going to Chengdu in China in a little less than three weeks’ time. I’ll be able to see if this helps me get past that Great Firewall of China, so I’ll still be able to get through to Facebook, etc, while I’m surfing the public WiFi over there.
I’m going to start work putting together this VPN Enabler app. If there is anyone interested in trying it out when I’m done, just drop me a note.

LDAP and slapd Version
Category : Technology/LDAPErrorOnMavericks.txt
I’m still trying to figure out why LDAP authentication for Dovecot and Postfix will work on Mountain Lion but not on Mavericks.
I’m baffled because the slapd server’s version is the same on both systems - version 2.4.28. So I’m going through every single configuration parameter - on LDAP, Dovecot and Postfix, and the configuration directories they use on the system, like /usr/lib/pam and /etc/pam.d.
I keep getting this error - "pam_ldap: error trying to bind as user (Insufficient access)”. Lots of leads on Google but no real breakthrough.

Broken LDAP on Mavericks
Category : Technology/LDAPMavericks.txt
I’ve released a new version of MailServe for Mavericks
with the LDAP authentication feature hidden because this broke on Mavericks and I’m struggling to find a solution for the time being.
This new version of MailServe (7.0.2) comes with one tiny new feature, though. There is now an option to inhibit the sending of the job completion report whenever the SpamBayes training job completes. I guess having that message clog up the in-tray gets tiresome after a while.
I’ve also updated LDAP Enabler for Mavericks
(3.0.1) to fix a bug with its De-Install process. I’ll continue to work on LDAP on Mavericks. If you’re interested in its progress, just let me know and I will send you any new updates I make. If I can solve it, that is.

BookNapper for iOS 7
Category : Technology/BookNapperiOS7.txt
I’ve released a slew of updates the last few days, including BookNapper
for iOS 7, which reminds me—I haven’t updated its screen shots on the App Store.
BookNapper is an app I wrote to allow me to keep a list of books that I’ve chanced upon in book stores, that I might like to read later on, if I can find it in our local library.
This is how it looks like in iOS 7 :
The point is, I’ve come to think that it looks better now in iOS 7 than in iOS 6. Here’s the screen shot from iOS 6
Which comes to the point I really want to make—Jony Ive’s remake of the iOS interface seems to have worked. There’s a vibrancy that’s apparent in spite of the “flatness”, or maybe because of the flatness. Now, looking at Mavericks, I believe we’re due a similar make-over for the Mac. It really needs a clean up.
Mavericks Torture Tests
Category : Technology/MavericksTortureTest.txt
I’ve tested MailServe for Mavericks (and all the other Enablers) as much as I can before placing them on my web site for people to use.
MailServe is a pretty deep product, with plenty of components and moving parts underneath. I thought I’ve tested every feature and fixed all the things I could see that had been broken — different versions of Postfix requires different configuration parameters and Apple is in the habit of swapping out Unix level command line tools without warning.
But I’ll still get mail like this
and I’ll have to scramble to test everything again.
So, if things don’t look like they’ve changed, it doesn’t mean that nothing has changed. Sometimes a lot has changed, underneath.

I have new versions of MailServe, DNS Enabler, DNS Agent, and WebMon for Mavericks.
Pardon me if I take a break. I’m quite exhausted getting them out and tested. I’m still working on them. I wish sometimes that Apple will stop making so many changes so often, if only to get some breathing space to actually build on this fantastic platform.

Category : Technology/BookNapperPlusGoodReads.txt
I built this app called BookNapper
so I can keep a list of books I want to read. Then when I'm in any one of the very excellent public libraries that we have here in Singapore, the app will tell me which of these books I want to read can be found there.
It's been working quite well and you can find it at the App Store
. But what I want to do now is make it work with Goodreads, so the books that are napped goes into a Goodreads Currently-Reading shelf and eventually to a Read shelf.
This is what I'm working on now (besides all the Mavericks stuff, that is, which I find a pain. Can't Apple leave us alone for a while so we can catch up with the technology, rather than change things every year?).

Luca in Chinese
Category : Technology/LucaInChinese.txt
Hai Hwee has been working on a Chinese-localised version of Luca:
That's how it will look like.
This version includes various bug fixes and speed improvements. It's a version we hope we'll be able to sell on the Mac App Store.
And then onwards to a version of Luca for the iPad.

Bug Fixes for Liya and LDAP Enabler
Category : Technology/NugFixesForLiyaAndLDAPEnablerforML.txt
Liya is now at version 2.0.11 (while the Mac App Store version remains stuck at version 2.0.9). I've fixed Liya so it'll handle SQLite fields declared as Bool. Liya will treat it as an integer, and map it to the NSNumber Cocoa data type.
LDAP Enabler is now at 2.0.2. In version 2.0.1, the password was not set correctly when a user was first created. You had to do a Change & Save Password explicitly to set the password correctly. Version 2.0.2 fixes this bug.
