As always, right in the middle of an AWS VPN problem and network issue that we're having. What's broken? Everything!
cjsuk··on Poop and Soda Bottles Threaten Air Force Rocket Program, Investigators Say
There were tool anchoring rules way before that, going back to the 1960s.
cjsuk··on Poop and Soda Bottles Threaten Air Force Rocket Program, Investigators Say
Indeed. And it doesn't work. Look at the sheer number of near world destroying accidents our military have managed to muster over the years.

I was actually working for a company that was a subcontractor to the USAF in the distant past. There is little room for individual creativity and ingenious problem solving in such a process heavy environment. It's actually like trying to work on an engineering project with Siri. The outcome of this is that only the problems allowed to be solved by the process are solved and none of the risks not identified by the process are reported, because it's too much paperwork already if you find a new one and you're not going to want your job to get any harder.

Ergo, all unidentified risks get taken because they are attractive solutions to many problems. Looking at the spanner incident pointed out by two sibling comments, the "dont carry heavy tools or anchor then when working on the big explodey thing" rule was not enforced and double-checked but hundreds of minor rules with precisely no benefit were being applied. Someone knew of that risk but didn't put the mitigation in place, probably because it was too hard.

Now military rigour and all of that doesn't like to be seen to be a turd sieve of a process so what happens is the answer is to add more processes, not look at the fundamental problem in the approach.

Overall, you need to focus on the key places where risk is considered high, but for most things, meh. Listening to people and making sure risk is managed effectively is a win.

cjsuk··on As of today, no US passenger airlines operate the Boeing 747
I watched an interview with him and apparently the reason was it worked out cheaper!
cjsuk··on Putting Apple’s iMac Pro Through the Paces
Yes. Exactly.

Also SSDs scare me more. MLC disks have so many states stored in a capacitor that is trusted not to leak over the lifetime of the device. All it takes is a few electrons to go walkies and it’s game over.

cjsuk··on Putting Apple’s iMac Pro Through the Paces
That’s fine but most of us are running on NTFS, HFS+ or ext4 where it matters.

And then there’s the same problem with MLC SSDs which are just arrays of capacitors encoding that state as different charge potentials. As a former EE, capacitors leak regardless of implementation.

I ran a lab notebook in word for a number of years and the document got fried by a filesystem error. The backup was toasted as well. This was corruption which broke the stage machine or parser in word which acted as a damage amplification.

As for the source of the error, we can only speculate but the possibility of a flipped bit is higher than you think.

Try running memtest86 on a PC without ECC for a week. You will be surprised at the results. I’ve seen perhaps 3 or 4 failures of this in new hardware. DRAM is not perfect.

cjsuk··on Putting Apple’s iMac Pro Through the Paces
As far as you know.

It only takes one bit wrong to fuck your file system.
cjsuk··on Why Am I So Lazy?
I agree. Another failure mode is that of my sister in law. She spent ten years throwing pens, pencils, paper, Lego, books, all in the bin because they make a mess.

Everything creative was an inconvenience.

Her eldest is in and out of prison. Her daughter was pregnant at 14. Her youngest is violent and has already got a social worker.

If every creative or intellectual outlet is taken away from someone or they are demotivated, what is left?

It makes me sad when I hear of parents prescribing anything negative.

That workaround makes me happy. Thank you - much appreciated!
cjsuk··on A list of macOS, tvOS and iOS bugs while helping my family over the holidays
The only bug I know of that actually annoys me is on the recommended music in the music app, when you click on the artist it redirects you back to the recommended playlist rather than the artist.

I really have had no other problems, which is a rather nice surprise if I'm honest.

cjsuk··on Open source modular synth software lets you create 70s & 80s electronic music
Yes. The phrases "menu" and "software update" are what kills all tactile electronic instruments of various kinds.

This is the same for electronic test equipment as well. There are so many features crammed in new devices, even if you manage to get enough controls for the basic cases on the front panel, a lot is still hidden in nested menus galore and they aren't necessarily sensible or discoverable or even work properly. This results in semi-religious fighting over which update is the least shit and people refusing to accept updates because they fear them.

The outcome, at least with electronics, is that you'll find a lot of 30-40 year old equipment nestling next to the state of the art with a sticker on it "for indication only". This equipment does a lot of the real work while the new stuff is used for validation and traceable measurements only. Due to rapid progress in technology, people cling to the last thing they felt any physical connection with.

This will pass in time as the status quo is accepted for younger generations. Fly by wire it is.

(I am incidentally a rather large fan of analogue and modular synthesizers and half built one in the late 1990s with 1970's electronic equipment, some of which I still own!)

Ah yes - mine had a notable bend in the shelf as well :)

They were only barely perceptible until someone told you about them. Then you saw them every time you looked at the screen :)

I do miss my 17" FD Trinitron monitor though. That was lovely. I didn't have enough money or room for a 21"

cjsuk··on iPhone 6 slows down by 28% after just 4 months use
I call bullshit. Reading the cached version, this is poorly disguised marketing lies for a third battery replacement service.

The test scenario was not described, this is only one sample which could have been selected and the source is not credible.

After 12 months of heavy daily usage on my 6s, I'm seeing 87% battery capacity left as an example after over 312 cycles. I am also seeing the same benchmark as the day I got it.

cjsuk··on Cities with Uber Have Lower Rates of Ambulance Usage
This is naive voice of someone who has never needed an effective healthcare system or faced many of the challenges that many do, such as chronic problems, unemployment etc.

What happens if it was your brother or sister dying? Not paying for them! Nice chap.

Healthcare costs are high because of lack of regulation and the ability for private enterprises to set costs. Profitability is not ethical when it comes to doing no harm. I’m sorry I can’t treat you, you can’t afford that option.

cjsuk··on I got locked out of my Google account for a month
This sort of stuff scares me so much. I see many people relying on one basket of eggs all the time (AWS is a fine example) with no backup plan.

I’ve actually considered running my own mail server again now DKIM/DMARC is around.

cjsuk··on Microsoft Surface Book 2 15-inch Review
> Dishonest designs like this should be punished by consumers

This needs to go one step further because consumers don't generally care about the design of the device until something goes wrong, at which point they get burned and lose their investment. Retailers then misinform them of their repair or replacement rights intentionally. Either the retailer should warranty it for the reasonable life of the device which has to be quoted on the front of the packaging with no questions asked or they have to meet certain repair criteria with a full refund no questions asked if they can't repair it under a certain amount of time (critically a short amount of time like 2 weeks)

Consumer Rights Act in the UK is the nearest thing to this and gives you a position to argue for fitness for purpose over the span of 6 years from purchase. But it doesn't go far enough.

With the above, the Surface Book wouldn't even make it to market which is how it should be. It's disposable and nothing in that price range should be disposable.

cjsuk··on Older Adults' Forgetfulness Tied to Faulty Brain Rhythms in Sleep
Couldn't agree more. UK here as well and there is a rather idiotic culture of social and binge drinking which I got into in the mid 1990s driven by "the pub" and "the club". I quit alcohol entirely in 2002 (15 years ago as well!) after getting married and decided to replace it with the magical elixir that cures all ills: water.

The revelation of water came from having a saline drip after an accident. I felt fantastic afterwards. Full of energy, drive and able to actually process things in my brain. Turned out I'd spent the few years before this point entirely shrivelled up with dehydration caused by drinking only tea and alcohol.

Trying to shake the caffeine monkey of my back now. That's just as bad. Drinking lots of water does help however.

Sorry I was being rather facetious there. They have VSM available (Application Guard). This is only on Enterprise edition because you know, only enterprises need a decent threat protection model...

Does it still run as SYSTEM? If so, fix that and come back later please.

It does but you can make it on demand.
cjsuk··on In the Middle Ages, the Upper Class Went Nuts for Almond Milk
I don't think it killed at lot of people but it was pre-pasteurization so fresh milk didn't keep in a drinkable state for very long. Most of it got turned into butter or cheese pretty quickly. Almond milk was almonds (with a long shelf life) and boiled water (relatively clean) so less risk.

I'm sure people got sick buying hooky milk though.
