Re: Install Clustered (4 nodes) Apache Kafka and Zookeeper on Ubuntu 10.04

hi jon zobrist,

The article is really good. I was testing a cluster myself of 2 systems and i reached the part where you get

imok from telnet and i opened the producer on one node and a consumer on other node....
I gave some entries on the producer system but I am not able to see the required output on the consumer. Do you have any idea why this might be happening...??

Re: Goodbye Linux Desktop, Hello Windows 7

Tim Szkobcov — Tue, 18 Sep 2012 16:27:23 -0000

I've been using linux (different distros) for the last 3 years as desktop os. Well, frankly 3 years of struggling, it hasn't been easy, but manageable. The last straw was to set up some java-based tax-office software :) There was no fun any more, I simply couldn't do that. So here I am on the good old Windows' road again!

Re: Automatic WordPress Database Backups Are Awesome

Kenneth Poulsen — Tue, 22 May 2012 05:46:18 -0000

Your forgetting one big thing though: WP-DBManager only backup your database nothing else, which means the pictures you upload to your posts will not be backed up.

I'm using the 'Backuper' plugin myself, it backup your entire cPanel account automatically.

I though about doing this but I couldn't find a way (other then developing a plugin) to automate this.

Hey Ryan, apologies for not responding sooner. Something was wrong with my disqus and I never saw this until now. I will post my create RAID script tonight.

Hi Jon. Did you manage to finish this script? Would love to take a look at it. I'm also trying to auto-create raid arrays (raid0 to be precise) on ec2 images. They need to be auto-created so I can make use of Amazon's autoscaling capabilities.

Re: Guest Blogger Brad Zobrist – How he would implement a Bitcasa

Here are some links related to Convergent Encryption, it looks promising, and explains how Bitcasa is doing what they claim.

A Convergent Encryption python module https://github.com/HITGmbH/... an interesting Convergent Encryption distributed file system http://tahoe-lafs.org/trac/...

Re: Guest Blogger Brad Zobrist – How he would implement a Bitcasa

jonzobrist — Sun, 18 Sep 2011 11:55:58 -0000

They apparently use "Convergent Encryption", which derives the key from the file, causing all encrypted versions to be the same post-encryption. More info here http://techcrunch.com/2011/...

The processor is a Q6600, it has 8GB ram, running Ubuntu Linux 10.04. I just use dyndns.com and connect it via my cable modem (which gets 8-12Mbps). The servers don't have more than a handful of players on them, so that may contribute to being able to run more.

What processor and bandwidth does your system have? Running 5 servers is something really good in Minecraft server hosting ....

Jon, you're a legend! I'll be honest most of your response is way over my head but I get the general idea. It was the answer I was hoping for. Thanks a million for the speedy reply. Take care.

Re: ICOD – 6.2.10 – Delete all SMS messages on iPhone

Jon Zobrist — Thu, 21 Apr 2011 13:43:01 -0000

I believe it permanently erases the messages from the SMS.db, which moved to /private/var/mobile/Library/SMS/sms.db

I had about 20 SMS, checked file size with ls -hl
ls -hl /private/var/mobile/Library/SMS/sms.db
-rw-r--r-- 1 mobile mobile 64K Apr 21 11:05 /private/var/mobile/Library/SMS/sms.db

Then ran Clear all SMS and it shrunk to 48K
ls -hl /private/var/mobile/Library/SMS/sms.db
-rw-r--r-- 1 mobile mobile 48K Apr 21 11:40 /private/var/mobile/Library/SMS/sms.db

Hope that helps!
-Jon

Vincent — Thu, 21 Apr 2011 13:26:06 -0000

Hi Jon,I'd be really grateful if you could answer a question for me. Does the Cydia App permanently erase all messages from the SMS.db so they can never be retrieved or does it simply clear them from the phones UI? I’ve searched for info on the app but there’s very little out there. As I said your help would be appreciated. Vincent

Re: Finally On EC2

Robio — Mon, 11 Apr 2011 18:52:23 -0000

I know it seems like I post on all of your articles and I do. The reason is because they are very useful. I setup my EC2 micro-instance about 5 months ago and it has worked like a champ (from your recommendation).

Posting more articles on EC2 would be really helpful. How about one on going from start to finish for a Wordpress install?

Be aware, if you use video out, or want to, this app may interfere with it if you're not in dynamic mode.
So, switch to dynamic switching mode when you need to connect an external display to your Macbook pro!

Re: ICOD – 6.2.10 – Delete all SMS messages on iPhone

Jon Zobrist — Sun, 31 Oct 2010 11:22:09 -0000

Thanks Matt! Indeed this is no longer the case, I have been running the updated version since your comment and have not had any issues. It works great, exactly as desired, I will update this post indicating the app works now and is much faster than the work around.
Thanks again,
Jon

Re: MCOD – 6.6.10 – Macbook Pro Core i5/Core i7 Battery Fix

Andrew Buckeridge — Mon, 04 Oct 2010 20:47:22 -0000

This is really dumb. It should disable the Nvida when using battery.
It would also be good if it went that way when Nvidia dies.
This will need to disable transition effects and other things that won't complete. It may have disable some apps. I.e. throw.

You should be able to lock it the other way - Intel HD only.
Should not use power hungry display solutions in laptops.

Looking at i5 because Intel HD is a non-Nvida option Apple now have. They should use it.

90s battery life? It would be bad if you still have a 90s battery.
Wirth's law is is what drives heat output of these incendiary devices.
Power consumption goes up geometrically as a function of time.

I had a dead MacBook Pro with no graphics that was just out of warranty. This was common problem a while ago. My old 00s 12" iBook with ATI is still going and won't die. I hope its fixed as OS X 10.3 on a G3 with full disc and no DVD is limiting.
