Error Code -43 macOS Sierra / OS X 10.12

December 15th, 2016

Under Mac OS X 10.12.1 aka macOS Sierra attempting to put files into the trash results in an error message:

The operation can't be completed because one or more
required items can't be found.
(Error code -43)

Currently a solution can not be googled that well: As general as the error message sounds there is a large heap of well meaning system care advice.

In my situation the problem seems to have been caused by no cleanly un-mounting CF cards and/or external hard drives.

A reboot makes the issue go away. Nothing more and nothing less required.

robo phone phishing

November 28th, 2014

3rd robo phishing call in as many days.
Today it spoofed my own number as it’s caller ID
and pretended to be AT&T. Telling me to enter
the last 4 of my social. Their scheme was that
my account had been “flagged”. Entering
false four digits prompted in a “flag has been removed”
message. So that people easier forget. I wonder what
people want to do with the combination of my
phone number and the last 4 of my social.

It is frightening to think that they might a have a success
rate in the double digit percentages with this scheme.


November 16th, 2014


Sunday morning, and Breakfast will only be served in 15 minutes.

Not feeling to open a book I visit:

A song comes up. Turns out I don’t have it, but I like it.

The iTunes music gave me grief before. So I use Amazon.
Or, let’s say I try to.

A song with a wikipedia page is obviously easy to find.
I can preview it. Yes, it is what I thought it would be.

No surprise that the purchase button is easy to.

They have a new player / app they like to push.
The old amazon downloader did not cause any troubles,
so I choose that one.
The file downloads in no time. That USED to be the problem:
Getting those large files to your computer.
Clicking on it, the mac tells me that this app is from an unidentified
In system preferences I tell it to open it anyway.
It does, but shows an empty screen.
In my downloads is still the amazon file. I click on that one.
Nothing happens. Well, not really nothing: The downloaded file
Then I go in Amazon to my purchases music. The song is not there
either. The 0.89 USD I spent will probably the only memory of those
3:18 (the length of the song) that I spent to get this song.

Buying music should be easy in 2014. It turns out in my specific
way of trying this it totally is not. I don’t buy music often. So I don’t feel
like researching all that might be involved.

I rather ramble here about it. Also since it is quiet symptomatic:

The actual act of copying a couple of bits to my computer is such a
small part of the overal action. It used to be that DRM was part of
the problem. It no longer is. Still have I have to deal with interfaces
and software that changes / breaks every time I like to use it.

The background is that the people running and maintaining these
systems do not care for the “Alpha to Omega - Experience” enough.

The late Mr Jobs was really good at making sure that things ran
as smooth as possible for certain flows from start to finish. If you don’t
then with computers and systems lots of ‘stuff’ will creep into the flow.
And the system will start depending on this extra stuff of other parts of
the system.

If you think that Byzantine bureaucracy was horrible then you have
no idea how our digital future will be.

the valley is behind us

September 27th, 2014

The first realistic rendering of a human in a computer I even laid eyes on got created by Chris Jones in Australia. If Intel would have any sense then they would give him everything he needs so that he can make a super bowl spot.

It is much easier for a director to dial in some emotions on an “Eckman board” rather than trying to coax them out of a drugged up little twat being full of itself. CAA better get their sh*t and required legislation together.

It will take a little while, but this WILL be a big deal: Completely artificial movies that just look like reality.

hiperos ? whoa that sucks

May 13th, 2014

Big corporations have their own problems. And if they don’t have them, then they create them. Like hiperos.

Imagine people reading a couple of Franz Kafka novels, putting them down and then proclaiming: “Hey lets build this (badly) and slap a web interface over it”
Of course they were intrigued by all the horrifying concepts and scary details in those nightmarish (yet awesome books) of that bohemian insurance clerk.

I wonder how much productivity gets lost by people waiting for hiperos to load, or trying to decipher what those random popups mean, how to find what
is missing in which form, etc etc etc.

Amazing how bad some things look in light of the second decade of the 21st century.

Validate fonts cleans up error message

May 3rd, 2014

On OS X 10.9.2 I got a message in /var/log/system.log like

Google Chrome Helper[23799]: CoreText CopyFontsForRequest received mig IPC error (FFFFFECC) from font server

whenever I opened a new Chrome window. (running version 34.0.1847.131)

Fixing this was surprisingly easy:

1) open Font book

2) select-ALL

3) Validate Fonts from the file menu.

Once I cleared the problematic ones the messages no longer appeared.

Canon support: awesome

May 2nd, 2014

I don’t have any expectations if it comes to end consumer support. These days I anticipate phone systems that will try very hard to make you give up. Should you reach a person they seem often not to care about your issues, their job or anything for that matter.

When I ran into questions with a recent Canon camera I called them anyway. I have been massively and positively surprised: After 90 seconds I spoke to somebody who cared. He had the camera I had in hand within a minute.
I sent them test pictures, and now they are looking at them. Regardless what the outcome of this investigation will be: I have the feeling that they care about their product and my experience with it.

As I said: I have not expected this. It will probably be a long time before I would consider another manufacturer. Unless there is a killer feature in a competitors product I will always look for a Canon device. I don’t mind paying more for it.
It might very well be that other companies have awesome support too. The risk to run into issues and they don’t is just to high.

So, yes, every support call is the chance to win a customer for life.

How odd that so few companies seem to understand this.

ping frequency of black boxes

April 5th, 2014

Today’s story on flight MH370 is that pings got picked up by a Chinese ships. Blackboxes seem to emit a signal every second for a couple of weeks.

Maybe it would be better if these devices would send a ping not every even second. Technically it should be easy to give black boxes a fix random
ping frequency. I probably would help that the device you are looking for emits a ping every 1.345 seconds.

And bigger batteries are probably a good idea as well.

jetset without overplay is dull

February 17th, 2014

Finally followed advice from a good friend and got overplay. Was super easy. Support was stellar. Netflix releasing House of Cards while I am on the wrong contintent?
Who cares …

Nice planet. But parts of it are a bit boring without any access to netflix etc.

Wells Fargo session.cgi from Statements & Documents

February 13th, 2014

I tried to download an online statement from the Wells Fargo today. What fun!

While I could do so for one account - on the one I needed I got nothing. I could select the year, or click on “Recent Statements”.

I called Wells Fargo. After ten minutes the first human I was able to talk to told me that I would need to speak to the online department for that.

So I was put on hold for another ten minutes. ( 1 800 956 44 42 would be their direct number). WF hold music cut deep grooves in my auditory system in the mean time.
It is the most obnixous loop one can think of. Amazing how they can literally have humans listen to this junk for years each day and nobody complains.

Once there was a human on the other end he was able to ‘enable online statements’ for the account in question. Not sure why that was not on in the first place.
After signing off and on again I did indeed my past records. Which is awesome.

I friendly declined the second offer from the WF operative if he could sell me any additional services at this point. That’s a bit like trying to sell timeshare junk to people
having a root canal.

All this would not be worth wasting any ink over. It’s just corporate America how it slogs along day after day extracting billions from people trying to get by (and from me too) .

When I clicked on the actual download link all I would find is a file called


Turns out that WF online puts the PDF statement into file with that name.

Renaming to


made it accessible. I decided not to spend another 20 minutes in the Wells Fargo phone loop to tell them about this unfortunate bug.

Media consumption in 2014

February 10th, 2014

4 months after I moved I connected the BluRay player. Turns out it was worth it: “Save the Tiger” is worth watching.

nest blinking red light

February 8th, 2014

I moved five months agao and had not installed the nest yet. When I hooked it up it only showed

a red blinking light

On top of the unit. It turned out that the device needed to get charged via the mini USB adapter in the back. After about 5 minutes, a small dull nest home screen showed up.
After maybe another minute the screen said:

Please attach display
to its base

It turns out that this message tends to be over optimistic: After connecting the device
it fell back into the red-blink slumber.

I gave the device 10 more minutes of USB charge. I used an actual physical charger, not a USB connection from a computer. The ampere that the unit sees can be quiet different.
A drained rechargeable battery certainly appreciates the flow a nice and solid current.
After said 10 minute charge things got better: the thermostat started ‘boot’ while being connected and it was able to operate the heat pump. At this point it still said

low battery

in the Wifi and other connection related screens. Since this did not change for an hour I gave the display another 30 minutes on the USB charger and then was able to set up the network connection as expected.

perl CPAN fails install DateTime::TimeZone

January 26th, 2014

doing a simple

perl -MCPAN -e shell
install DateTime::TimeZone

the screen starting throwing LOTS of errors at me. And they end along the lines of:

... skipped lots of output ...
t/10deprecated.t   (Wstat: 512 Tests: 0 Failed: 0)
  Non-zero exit status: 2
  Parse errors: No plan found in TAP output
Files=12, Tests=0,  0 wallclock secs ( 0.04 usr  0.03 sys +  0.26 cusr  0.05 csys =  0.38 CPU)
Result: FAIL
Failed 10/12 test programs. 0/0 subtests failed.
make: *** [test_dynamic] Error 255
  /usr/bin/make test -- NOT OK
Running make install
  make test had returned bad status, won't install without force

That does not look so promising - does it?

Actually the fix was easier than the output had let me to believe. Scrolling up I saw there were lots of errors starting like

Can't locate Params/ in @INC ...

When I tried to do a

install Params::Validate

I got a similar error - just now Attribute/

Much to my happiness

install Attribute::Handlers

actually worked. After that Params/Validate could be installed and finally I was back on track with installing the module that I actually wanted.

I do not know why my CPAN install is not having the right understanding of its proper pre requisites. Since this worked for me I probably will not find out …

learning vim

December 19th, 2013

First there is ‘vimtutor’ which covers the basics.

Drew Neil publishes insightful screen casts about vim.

Bram Moolar himself has a great commented page about books he recommends about vim. [A little bit as if Jesus would point out his favorite Bibles]

These vim keyboard maps might be handy. Not sure since I have not used those yet.

LSI megaraid write cache via CacheCade

October 14th, 2013

If you like to use the MegaRAID write cache feature make sure that you indeed have a version 2.0 key.

Version 2 keys have the part number LSI00292 while Version 1 keys have the part number LSI00248.

It is possible to get the Version 1 flavor, since both keys share a part number. If you use a Version 1 key
nothing will say this in the MegaRAID “WebBIOS” software or any of the command line tools that LSI offers.
The only indicator will be the part number on the packaging and the fact that write cache will not be enabled.

avoid enum suggestions in mysql procedure analyse()

August 23rd, 2013

If you don’t want to see enum suggestions in a mysql procedure analyse() call on a table then you simply run it like:

select * from table_name procedure analyse(1,1) \G

The (1,1) will always show you non enum solutions for each column.

Firefox 22 . Mac OS X 10.6.8 and Quicktime 7.6

July 2nd, 2013

It seems that in any dying project the bureaucrats, middle managers and otherwise challenged people are the last to leave. They cling on to past greatness and try to re-evoke what is gone.

The last Firefox update 22 put the latest available Quicktime Version 7.6.8 on their blocklist. Clips will not longer play, but a warning will show up, requesting an update. Only problem is that Quicktime 7.6.6 is not out of date for OS X 10.6.8. FF has acknowledged this and it is fixed. But a download of FF still has the broken blocklist.xml.

If you want or need to fix this manually you can do:

1) locate blocklist.xml for instance via

mdfind blocklist.xml

2) remove the 3 lines:

<pluginitem blockID=\"p408\">
<match name=\"filename\" exp=\"QuickTime Plugin\.plugin\" />                      <versionrange minVersion=\"0\" maxVersion=\"7.7.0\" severity=\"0\" vulnerabilitystatus=\"1\"></versionrange>

3) restart Firefox

infinite sar display - neat option

May 21st, 2013

wanting watch sar run in a terminal in linux indefinitely one can start it with

sar 1 0

The first number indicates the sampling time in seconds. The second number is usually the number of samples you like ot see.

If this number is 0 then sar will not stop. And as another bonus will look at how large the terminal is and will display a new header

Command line can be user friendly. I really like those little gems that show up in all software: People spending their time to make something better. It is like a little gift to the world. With software the value of even a little detail can potentially be significant. Which is an awesome thing.

For all we know it might very well be that the feature described here will please people in a hundred years from now.

I don’t think that mankind will manage to drop unix at this point. Neither can it give up on the use of steel. Yes there might be new systems, much like there have been new materials.

The new gets all the attention. But in many cases the new will not replace the old entirely. Only journalists tend to think that way. In reality the findings of Mr Newton help Boeing and Airbus today to build tubes with wings that shuttle people around the globe close to the sound of speed.

I hate this guy

March 11th, 2013

Working on some code which is from 1992. Amazing fact number one is that the bits did not rot. Still compiles like a charm. But I really really hate the guy who wrote it. I know that back in the day storage was an issue. Things needed to be a bit more optimized than today. But having it all come down to a line like:

pos1 = ((*(*(l+x)+y)));

feels a bit outdated. Sure, it still works. Couple of comments could have been nice. Those extra brackets barely make up for it. I think the best thing that the author of those lines did, was not to get under a bus or die in any other way: I would not be here in that case.

Thermaltake BlacX seing 801.57 GB on a 3TB disk

July 14th, 2012

For time machine and other local data needs I really like a drop in design for an external disk. When drives were cheap it was so nice just to drop them into the ‘enclosure’ and go on.

I ended up buying and liking the BlacX ones from Thermaltake. Slight cheap electronic stench when you open them. 1 out 5 that I bought ended up not working. But the price was really right.

Unfortunately the love ends with larger than 2TB drives. It seems to say somewhere in the specs for the device. The model I have is old too.

But it is still a bit of a let down if a 3.0 Tb drive only shows you 801.57 GB in ‘Generic External Media’ in Disk Utility under OS X.

I remember having spent hours at a client in 1987 trying to get their whopping 30 Megabyte hard drive to work with the limitation of the initial FAT16 allocation table.

There have been countless problems caused by an “oh this kind of system will last for sooo long” engineering attitude since then. “Nobody will want to have so much space, speed, insert-thing-here.”

People seem to have a hard time estimating how long something will be around - and in what kind of world things might have to fit in.

Doing those underlying things ‘right’, making them easily extendable for instance, creates tremendous value.

If Amazon actually manages to continue to fully implement their SOA approach then we might be hearing from that for quiet a while. They are currently one of the few companies that positively surprise me when I interact with them.

We will see. And I wonder what kind of size limit the new drive enclosures have that I just ordered.

leap second - the buck stops over there …

July 1st, 2012

Skimming over the news (a bad thing in itself I must admit) it seems that the leap second addition - one might tempted to say - between June 30 and July 1st caused allot of Java based systems to fail.

While the headlines list who got affected and all that it is interesting that there was no reference to responsibility. Outages in general are news. Like the one on this recent Friday that took AMZN service and then some systems down.

In general it is all in a ‘oh well’ state. “shit happens”.

This attitude is awesome for technology providers: Not once saw I reference to who owns Java in those leap second bug reports. Sun did. Sun got bought by Oracle. Larry Ellison, principal and I guess at least part time owner of Oracle picked up a nice Hawaiian island the other day. How about he offers sys admins working late to work around HIS bugs a complimentary stay there?

medical imaging

December 16th, 2011

So glad I found this great introduction and overview of medical imaging.

I liked the article since it gives a great overview of different techniques together with their genesis. Stuff like a PET scanner does not rain down on humanity. Lots of people needed to work hard to realize it. Ideas, Patents and -as it turns out- the Beatles were needed and involved.

I personally found it fascinating how much ample computation power has enabled. Nothing that mattered in the last 40 years would have been conceivable without massive numerical processing. Even 99.999% of computing power is wasted on Facebook and games it is just awesome that we people deviced instruments to compute so cheaply.

It is probably impossible to estimate the impact that technologies like DfMRI will have on our knowledge and picture of ourselves. The microscope changed the world and each of our lives in the most radical ways. Which might only have dawned on people in the 17th century.

Of course the link was found in Wikipedia. After having set up a monthly donation to them and knowing how good it feels now and will do in the future I wonder why I did not do so earlier. Specially learning new things most Wikipedia pages allow a quick overview about the topic. What I personally really love is how detailed yet concise even very specialized topics are being documented. Quiet brilliant.

loving a suitcase?

November 18th, 2011

Last century we bought 3 full size Samsonite Oyster suitcases. Back then you had to put some stickers on them to distinguish them from all the others that people had.
That changed. Now there are all those black soft textile bags on the belt. I never understood why.

Those suitcases are simply amazing. They have traveled ridiculous miles by now. Life is tough if you are luggage. I can not imagine what kind of treatment they have gone through. They always worked.

I was very saddened when he lock broke on one of them. I don’t think I want any other suitcase. Rimowa seems to be en vogue. But I feel that they would not work better and probably look pretty beat up within a couple of months. I also don’t like if my luggage tells the world “Hey - check this out - I have money - stealing here is worth the risk”.

But as it turns out Samsonite did not only make awesome products, their service rocks as well:

I emailed them, asking if I could order a spare lock. They asked for my address and will send me a replacement lock for free.

I love it if things work right. I think this kind of service is truly inspiring.

Me loves my Samsonites!

Science PR - good luck getting the Manhattan Project going today

September 23rd, 2011

Yesterday two ’science stories’ ‘broke’: “Neutrinos traveling faster than light” and “Computers can read images out of the brain”. I am borderline clueless on matters of physics, so I leave that one alone. The fMRI mashup by Nishimoto et al is borderline in my view. The presentation of their findings makes it way to easy to drum up headlines like “Brain Imaging Reveals What You’re Watching” or “Scientists Reconstruct Brains’ Visions Into Digital Video ”

Only spending little time with the setup it seems that the experiement pretty much reveals that 5,000 hours of youtube video are so stereotypical that even a fMRI of the v1 can match some patterns back. For a given individual, after hours of learning. To suggest that the video shown on the right as ‘coming out’ of the brain is extremely misleading.

Having two of those studies in one day means nothing of course. But one can go off on a tangent and wonder why - I am sure wonderful - people and scientists drop science in exchange for head lines and eyeball. Maybe it is time to decide over the 2012 budget? And I am sure that given realities of today it is much to get money for “we can go back in time” or “we can film your dreams”.

I have doubts that the Manhattan Project would have a chance today. Rewind to 1940: Some professors had drawn some numbers on chalk board. Up this day only very few
people understood what they were talking about. I certainly have no clue. They had no computer simulated films. They had no precedence. The bomb they were talking about
was by multiple magnitudes bigger than anything that had done before. There was nothing in reality to show for. Just scribblings on a chalkboard. And some common consensus among a few people. One could see this happening if they would have asked to disappear into the desert to do a bit of thinking. But they needed a bit more: Factories bigger than anything else that had been built. And 10% of all electricity in the entire US to run them. To make a handful of matter that -according to science- might make one big boom.
All based on science. And politicians and military people did go with it. And they built different models that both worked after five years.

apple: don’t bother

September 18th, 2011

iTunes just rejected to play a song that I purchased 3 years ago, since it told me I need to authenticate my current computer.
Instead of trying to figure out what is broken with the Apple authentication for that song I just went ahead and bought it again on Amazon. Without CRM.

Apple is notorious for having one of the worst user management systems for their online services. The documentation of my Apple ID changes and resets
spans many pages. There are none for other systems and services that I used equally long.

Funny how one company can be so great in a couple of areas and fail so consistently in others.

requested architecture/executable not found

June 30th, 2011

On a recent Macbook Pro (i7, Macbook Pro 8.1) post Feb 2011 I did not have much love from a kernel driver. Oddly google was not that helpful.

/var/log/system.log system log complained along the lines of:

/System/Library/Extensions/HuaweiDataCardActivateDriver.kext failed to load -
(libkern/kext) requested architecture/executable not found;
check the system/kernel logs for errors or try kextutil(8).

The fix was pretty simple: Just boot the machine into 32bit mode. Turns out the default boot mode is 64bit on later hardware. One way to find out which OS mode you run is to go to:

About this Mac
More Info …
click directly on the Software item on the left.

You will see 64-bit Kernel and Extensions: “Yes” in the second last line.

If you hold the numbers 3 and 2 during boot then you will be in 32bit mode and get probably much more love from 32 bit extension. In my case it was an Aldi Surfstick S4012 based on a Huawei one that caused some grief in 64bit.

Since not many 64 native machines are out there it explains why this topic is not easier to google right now.

I miss my Onyxes

May 19th, 2011

A, the good old days, when I had hair (well kinda) and computers were large, big and expensive.
These emulators from Nvidia reminded me of that time back last century.
And they also get to show how much horsepower actually is in a modern day GPU.

The invisble hand of working stuff.

March 28th, 2011

Switching machines I realized that I had to re-install webmailer. This wonderful preference plane lets you launch any web based mail program whenever your default mail application would be launched.

I have used it for years. Thousands of times. And it always worked.

And I failed to appreciate that. Going through our lives our attention is where we need to act or avoid. The broken and annoying stuff is what we notice.

All the well working things that surround us go naturally under appreciated. And, since people have piled up allot of technology and culture in the last couple of generations there is actually a huge amount of that.

If a thousand items worked and one does not, that one will be all we think about.

The end of Nokia

February 11th, 2011

A good summary of what happened to Nokia. Point is that engineers can not run the show. But -of course- all the prettiest design in the world can not safe a project / company if the underlying technology is not up to the task.

I’d kill him

January 21st, 2011

If I ever find that engineer that told the users that the way computers worked could be changed I’d kill him. He had it coming. He probably told those proto-users also that it would be complicated etc etc. But he had already lost them. All they remember is that they can change their mind. The how and why they don’t care about. “you can make that work, right”. No more planning. No more thought. Just charge ahead wherever your mind and dreams might guide you.

All goes to hell, since nobody thought about anything? No big deal. Can be changed. It’s easy, right?

Next profession I choose involves a chisel, a hammer and preferably rocks. Also handy to have something to throw on the floor at all times.
