Finder: maybe the best free duplicate file finder program (via: Mac-Forums Discussions)
Posted by jpluimers on 2014/09/29
Every once in a while you’re looking for a solution to a problem, and slap yourself to the head that you’ve been overlooking a real obvious solution.
This case: finding duplicate files on Mac OS X.
pendlewitch had this great tip: use the Finder!
You can do this in Finder for free, it’s a bit time consuming but if you’ll get them all eventually.
- Open a new Finder window
- In the search field, enter the wild card asterisk symbol *
- Arrange by Size
I find it best in List view.
Prepare to be gobsmacked at how much duplication you do have.
I totally agree with his last sentence (:

Solution for opensuse 12.2: yast “System Services (Runlevel): Services” very slow
Posted by jpluimers on 2014/09/26
Thanks to the wonderful people at the opensuse forums (especially Knurpht and wolfi323) for helping me out with opensuse 12.2: yast “System Services (Runlevel): Services” very slow: how to investigate.
The solution is to install openldap2, then reboot.
The easiest way is to perform this under sudo:
zypper install openldap2
Somehow in opensuse 12.2 yast, sendmail and apache depend on it (though the yast/zypper software installer don’t recognize the dependency).
Without the reboot, yast was still slow. Not sure why yet.
I will need to check this out in the most current opensuse release.

bash vulnerability; patch your *n*x boxes A.S.A.P. (via: CERT/NIST reveal level 10 bash alert today, 24 September 2014)
Posted by jpluimers on 2014/09/25
Unpatched bash allows for remote code execution.
Patch as soon as you can and be aware that the current patches might not be complete.
Many vendors (including Debian, Red Hat, SuSE, Ubuntu) already have patches available: CERT/NIST reveal level 10 bash alert today, 24 September 2014.
This is a long article which explains the why/how/… and has an easy check to see if you are vulnerable: What is the CVE-2014-6271 bash vulnerability and, how do I fix it.
It looks like the current patches aren’t complete yet, but do plug big parts of the hole.
Watch bash CVEs in Ubuntu and CVE-2014-7169 in Ubuntu (and maybe for other nx varieties as well).
Update:
- Easiest test through https://github.com/hannob/bashcheck:
curl https://raw.githubusercontent.com/hannob/bashcheck/master/bashcheck > bashcheck.sh
less bashcheck.sh # check if there is nothing fishy
chmod +x bashcheck.sh && ./bashcheck.sh

A few must watch videos on test driven development and unit testing
Posted by jpluimers on 2014/09/25
If you are going to do test driven development and unit testing, you should watch these videos and slide decks, most of them by Miško Hevery:
- Not a video, but a good starter: Guide: Writing Testable Code (or read the PDF version).
- 0:32:07 ▶ “The Clean Code Talks — Unit Testing” – YouTube.
- slides: Clean Code Talks – Unit Testing (Q&A: be careful that Monkey Patching does clean up after itself and not infect the global state).

Delphi poor mans debugging trick: approximate the source location of an exception address
Posted by jpluimers on 2014/09/24
A while ago, I had a client with an exception on a workstation.
There was no permission to run a debugger on their system, or use something like MadExcept or Exceptional Magic in their code base.
The exception looked like this:
--------------------------- Application Error --------------------------- Exception EInOutError in module MyApplication.exe at 001656B1.File access denied. --------------------------- OK ---------------------------
These are the steps to get at the source line in an x86 Delphi program (I still have to try the x64, but presume it works similarly): Read the rest of this entry »

Generate XSD from XML – XSD.EXE versus on-line tools – take 2
Posted by jpluimers on 2014/09/23
Almost 4 years ago, I compared XSD.EXE to some on-line tools. Time for a follow-up.
From the old post:
- Online Flame-Ware XML-2-XSD 2.0
- HiT Software XML utilities (registration required)
- XmlForAsp XML Schema Generator
XML Utilities has since then moved to a new domain: www.xmlutilities.net; the other 2 are still at their original locations.
New on-line generators I got pointed at by Mark O’Connor’s stackoverflow answer:
- Free Online XSD/XML Schema Generator From XML – FreeFormatter.com.
- XML to XSD Generater Online – xmlGrid.net.
Neither of them can generate the XML types separately like XmlForAsp XML Schema Generator does.
But the first one does get attributes right, whereas all the others often skip some or all of the attributes.

Optimal posting time? (via: Are there optimal days/hours to post questions in order to get visibility and answers? – Meta Super User)
Posted by jpluimers on 2014/09/22
A while ago, i came across this interesting question: Are there optimal days/hours to post questions in order to get visibility and answers? – Meta Super User.
The recommended time 1400 UTC is related to my blog post scheduling behaviour.
Virtually all my blog posts are either (when both apply at the same time, that is pure coincidence):
- scheduled at 0600 WordPress time (which varies because of DST; usually it is either 0600 UTC or 0600 UTC+1)
- about “real world” events and just posted on the spot
I schedule posts on Monday through Friday:
- Monday + Friday I focus on Power User / Lifehacker topics
- Tuesday, Wednesday and Thursday I focus on Development topics
Difference between 0600 UTC and 1400 UTC
So why the time difference of about 8 hours between 0600 UTC and 1400 UTC?
That has to do with the public I generally interact with: software developers speaking English, mainly living in European and USA, with a minority in India, Asia and down-under.
- At 0600 UTC, most Europeans are about to wake up or just arrived at work, so they get fresh content. Still quite a few people from India and Asia are up (returning from work) can read it the same day it was posted. And virtually everyone in the USA is still sleeping, so they get fresh content too.
- At 1400 UTC, most Europeans are at work, people at the USA East Coast just started working and the rest of the USA is waking up and (hopefully) going to work. So you get a huge group of on-line people online with a high chance if comment/answer interaction on your question: great for getting answers on the same day.
