Why good metrics do not equal good quality

A short while ago I posted an article on the codecentric blog about why good metrics can be, but need not be equal to good software quality. As I wrote earlier, I will add links to this blog whenever I post something of interest to the company site.The post is available in both English and German at http://blog.codecentric.de/en/2011/10/why-good-metrics-values-do-not-equal-good-quality.

List all open Safari tabs across windows

Image
Over the course of a workday I tend to accumulate lots of browser windows, and even more tabs inside them.  Up to now, I would often lose track of what which tabs were open in which window and in which space. In the end, I would often just open a page again in a new tab of the window I happened to be in at the moment, increasing the overall clutter.
With the advent of persistent application state across reboots or application restarts as well as fullscreen apps in Mac OS X Lion that situation has gotten even worse.

The "Window" menu in Safari does not help too much, because it only shows the tabs of the currently focussed window. Today, while wondering why a website was not displaying correctly, I accidentally found a remarkably simple (and built-in!) way of showing all open tabs across all open Safari windows.

Just hit Cmd-Alt-A or pick "Activity" from the Window menu in any Safari window to open or focus the Activity overlay window.

It is usually used to determin…

com.apple.dock.extra.xpc needs to take control

Image
After my recent Mac OS X 10.7 Lion upgrade I was greeted with a dialog box after reboot telling me that
com.apple.dock.extra.xpc needs to take control of another process for debugging to continue. Type the name and password of a user in the "Developer Tools" group to allow this.
No problem, I thought, and entered my credentials. Alas, to no avail. My name and password were rejected, which had me a little panicked at first, because I thought the OS upgrade might somehow have botched my account, potentially locking me out of my Mac later.

Hitting cancel would only get rid of the message for a few seconds, then it would reappear, again and again.
Turns out the solution was quite easy: Go the Mac App Store and download Xcode 4.1. Once the installer has finished downloading, run it to replace the Snow Leopard version of Xcode 4.0 with a Lion compatible one. Once that is done, the message will not appear again.

Please note: Maybe I could somehow have fiddled with my accounts privil…

Lion Finder Source List Icon Size

Image
[Update]As can be read on Mac OS X Hints here, this setting also applies to the side bar in Mail.[/Update]Apple has - as was to be expected - slightly modified the appearance of many Mac OS X controls in 10.7 "Lion". Some of those changes have caused protest and debate around the net, but I believe this is just the same as it is with face-lifted car designs, which means in a few weeks everyone will have gotten used to the new style and consider the previous version old-fashioned.However, there is one particular little issue that I could tell I would not come to like immediately: The icons - and more importantly the font-size - in the Finder's left hand sidebar is way bigger than it was in Snow Leopard. This makes the source list look much more cluttered in my opinion.At first, I headed for the Finder's View Options context menu, but there's nothing there to change the sidebars appearance. A little more digging then brought me to the General preference panel in Sy…

A Short Story on a Waste Of Time

This is about wasting a lot of time, effort and some energy on an unfortunately not so successful transition from smaller to bigger disks. Actors include a few external drives, Time Machine, an iMac with a dying system disk and me, being a little stupid. Fortunately there were no really serious consequences, however if I ever face a similar situation again, I might come here and read up on how to migrate systems and backups more sensibly.

Using JMeter to measure binary protocols

This is just a short post linking to an entry I recently posted on my company's blog. It is about Using JMeter to measure binary protocols, which I recently had to do in a customer project. It is very well possible that in the future there might be more posts there than here, but I will make sure there are links posted to this blog. Please note, that the JMeter article is available in both English and German.

iOS Feature creep hurts usability

Image
I have been a user of the iPod Touch from day one. With the iPhones being tied to unreasonably expensive mobile phone contracts it was never an option for me to buy one just for fun. But when the iPod Touch was announced I knew this was my device. I have been updating iOS whenever there was an update available, and usually I was pleased with what Apple had refined and added.However, one thing has been bothering me for some time now, and I did not know if it was me getting older, or if really something had changed with the OS.

On Writing a Book, Pt. 5 - The Contract

Image
This is part five of an ongoing series about my experiences while writing the MySQL Admin Cookbook for Packt Publishing. All previous parts can be found under the mysql-admin-cookbook label.After the initial discussions about the book’s outline which I described in part 2 of this series were underway, talks about the actual writing contract started. Naturally, neither Udo nor I had any experience with publishing companies and the contracts between them and their authors. Add to that the fact that we are both from Germany and had had little to no experience with English legal stuff of any kind - apart from the usual 5000 pages EULAs you just “agree to” by clicking the “go away” button as quickly as possible - and you will probably understand that we were a little nervous about what we should expect.

TotalFinder - A must have addition to Mac OS X

As a former long time Windows user I have quite successfully (and since Steam has arrived completely) transitioned to the Mac platform. It took some time, but over the past two and a half years I have found replacements and substitutes for most programs I used regularly on Windows for everyday tasks and must say I don’t look back.Ok, there are some things I installed to make the base system a little more comfortable, e. g. by installing Better Touch Tool or iStat Menus which allow for better leveraging of available hardware features. But other than that - I haven’t made up my mind about TextExpander yet - there is little left to be desired.Except: File and window management… Say what you will about Windows, but one are where it still runs circles around stock Snow Leopard is window and file management. Aero Peek - docking Windows to the screen edges and having them become exactly half the screen size - is a welcome addition to BTT, and Expos√© is also usable. But still, the Windows exp…
