A Word file that crashes the Macbook hard disk

Believe it or not, I was editing this week a document that I received by email. After 3 minutes Word Mac 2011, Version 14 crashed, leaving only a temporary file back on my OSX 10.7.4 desktop.

As restarting Word did not work, I used disk utility, that recommended to be started from another disk.

When doing so, it recommended to reformat my hard disk (which I did). Continue reading A Word file that crashes the Macbook hard disk

Sync Lion desktop via iCloud

While all that sync’ing works quite well, I still have different desktops on my MacBooks.
Here is a solution that is based on some undocumented feature of the iCloud that I have found at macstories.net. It basically needs to activate the iCloud settings also for files which will give you in Lion access to a magic 5 GB ~/Library/Mobile Document folder very much alike to Dropbox.
I am rsyncing here now my Desktop folder by an automator action as described at banana.com. Can be done in less than 5 minutes…

Infinite stupidity?

This is a new Edge conversation with Mark D Pagel.

A tiny number of ideas can go a long way, as we’ve seen. And the Internet makes that more and more likely. What’s happening is that we might, in fact, be at a time in our history where we’re being domesticated by these great big societal things, such as Facebook and the Internet. We’re being domesticated by them, because fewer and fewer and fewer of us have to be innovators to get by. Continue reading Infinite stupidity?

Computers are like bicycles for our mind (Steve Jobs)

or in his won words

Your time is limited, so don't waste it living someone else's life. Don't be trapped by dogma - which is living with the results of other people's thinking. Don't let the noise of other's opinions drown out your own inner voice. And most important, have the courage to follow your heart and intuition. They somehow already know what you truly want to become. Everything else is secondary.

Less than one mistake in every 6 million deliveries

I have seen recently a TV documentation about the Dabbawalas in Mumbai who deliver freshly cooked food to the workplaces and return the empty boxes back to the customer’s home. According to Wikiedia.

In 2002, Forbes Magazine found its reliability to be that of a six sigma standard. More than 175,000 or 200,000 lunch boxes get moved every day by an estimated 4,500 to 5,000 dabbawalas, all with an extremely small nominal fee and with utmost punctuality Continue reading Less than one mistake in every 6 million deliveries

A Mac OSX journalling error can inhibit the boot disk to be mounted

The screenshot below shows my desperate search why my Macbook wouldn’t boot again (following a cold reset writing a large Photoshop CS5 file for more than 15 minutes).

The verbose boot mode (APPLE+S) showed some error with the journalling system, basically an error as described at the currently non functioning Apple Support Board

jnl: replay_journal: bad block list header @ 0x4bra50 (checksum 0xega0fee1 != 0x927a5993)
jnl: journal_open: Error replaying the journal!
hfs: early jnl init: failed to open/create the journal (retval 0).

Unfortunately nothing helped. Booting from an external disk just showed a normal, error-free HD in disk utility. Continue reading A Mac OSX journalling error can inhibit the boot disk to be mounted

Optimized SSD under OSX

Having now a SSD in use for more than one year, here are my accumulated tweaks. The first one is Smart Sleep which greatly enhances sleeping/wakening time. Disabling the motion sensor (“sudo pmset -a sms 0”) doesn’t hurt but is isn’t really necessary. Mounting the SSD noatime , however, gives a measurable performance gain. And at the end, I dropped that RAM thingy as it breaks with every system update.

R cloud computing

A recent article on WPA hacking using the Amzon EC2 cloud computing facility let me wonder whether there couldn’t be more useful projects. For example gene-gene interaction testing would be nice – indeed somebody has already setup a possibility to use R: Robert Grossman, director at the Informatics at the Institute for Genomics and Systems Biology. Great, many thanks!
What’s even better, a

… 60 Genomes dataset can be found here, as part of the public data that Bionimbus makes available to researchers. With the Bionimbus Community Cloud, the data is available via both the commodity Internet, as well as via high performance research networks, such as the National LambdaRail and Internet2 … If you are a member of the Bionimbus Community Cloud, then you don't need to download the data but can compute over the data directly with Bionimbus. Currently, we are not making the Bionimbus Cloud generally available, but expect to do so beginning in approximately June, 2011.

Mac wallpaper with notifications

Do you want to know what the large figures on my desktop mean? These are the counts of important emails (with sender in my addressbook), all other unread emails as well as unread RSS feeds.

It turned out to be a bit tricky what to enter into the Geektool shell window – here is my solution:
