From Mssrs Pratchett & Gaimain

Footnote from Good Omens, by Terry Pratchett and Neil Gaiman:

"NOTE FOR YOUNG PEOPLE AND AMERICANS: One shilling = Five Pee. It helps to understand the antique finances of the Witchfinder Army if you know the original British monetary system:

Two farthings = One Ha'penny. Two ha'pennies = One Penny. Three pennies = A Thrupenny Bit. Two Thrupences = A Sixpence. Two Sixpences = One Shilling, or Bob. Two Bob = A Florin. One Florin and one Sixpence = Half a Crown. Four Half Crowns = Ten Bob Note. Two Ten Bob Notes = One Pound (or 240 pennies). One Pound and One Shilling = One Guinea.

The British resisted decimalized currency for a long time because they thought it was too complicated."

Battle of the retro Unix desktops: NsCDE versus CDE

John Riddoch

Re: RAM usage

We had CDE running on Sparcstation 4s & 5s back in the day - I think they only had 16MB or 32MB of RAM. Some of the SS5s only had a 500MB hard drive (that was fun shoe-horning Solaris onto...), let alone memory.

One part might also be a move to 64-bit which has a tendency to inflate binary sizes, but that should only be a doubling at most and probably much less.

Re: Nasty goings on

Late 90s/early noughties you could pretty much guarantee that ANY web search no matter how innocent would consist of about 50% porn links. It was fairly common to search for "search term -sex" to at least try and filter out some of it.

Tough news for Apple as EU makes USB-C common charging port for most electronic devices

Ah, earth problems...

Had a much less hair raising experience with that - bought a 2nd hand guitar and got a chunk off because it was buzzing loudly when plugged into the amp. Took it to bits and discovered they'd wired the jack socket wrongly when it was replaced... 5 minute solder job to switch round the wires and no more buzzing :)

Now onto fixing the other issues like the frets needing polished, rusty screws replaced and updating the pots (one doesn't work, so might as well switch out the cheap ones for better models). I'm beginning to think I didn't so much buy the guitar as rescue it from neglect...

Co-inventor of Ethernet David Boggs dies aged 71

John Riddoch

Re: Ethernet turned out to become the network winner

Back in the 90s, our uni lecturer was convinced that Ethernet was doomed and ATM was where it was all going. What changed was the move from coax, with all its myriad problems and relatively dumb hubs to fully switched networks. These helped reduce/remove the collisions which plagued early Ethernet networks and allowed it to scale up and out.

What is ironic is that Ethernet followed ALOHAnet which was a wireless protocol, making it wired. We've now taken Ethernet back to wireless with our wifi links. Everything turns full circle...

UK internet pioneer Cliff Stanford has died

John Riddoch

Re: Sad news.

Aberdeen had Wintermute, I think I was with them before Demon. The Wayback machine shows my site on Demon from 97 to 2001 before I moved to ADSL, so I suspect I must been on Wintermute in 95 (when I left uni and lost the free access there) until moving to Demon in 97. IIRC, Wintermute folded or something, so that probably precipitated my move...

IBM cannot kill this age-discrimination lawsuit linked to CEO

John Riddoch

Re: This has been going on long enough

Pretty much... "Sign here and get a guaranteed payout and go away. Or take it to trial, where our lawyers are better paid and you might get nothing and have to pay our legal fees. Your call...."

Not hard to see why they might just take the settlement and sign the NDA. There might come a time that someone is willing to take it to court on principal, but it'll take strong principles and dedication to go through it all.

IBM would, of course, argue that they're just minimising risk and seeking closure to the whole thing and just trying to save their ex-employee from a gruelling court case.

China details relocation plan for up to five million datacenter racks

John Riddoch

Surely a typo?

65% availability would mean it was unavailable 1 day out of 3, or over 2 days a week. If that's what is delivered, it's going to be a tough sell to get anyone to use the new data centres.

"it mysteriously disappeared from the disk and its backup did not work either." - so they had a backup, presumably on a second floppy; these are the days when code could fit on a single floppy after all. My guess is the first copy nuked itself, so they loaded the 2nd copy into the PC and ran it with the same result.

Re: I bet it all comes down to services!

In house IT teams will generally put in a bit more effort to keep things ticking over; it's in their interest, after all, since it's job stability, performance bonuses and share options in many cases. Outsourced IT workers will generally do the minimum required to meet the SLA and service improvements won't happen unless it's billable (at an appropriate markup, obviously).

Toshiba reveals 30TB disk drive to arrive by 2024

John Riddoch

RAID is fine, up to the point it takes so long to rebuild the replaced disk that another disk fails in the meantime. I think we got to the point that RAID 5 was no longer "good enough" because the chance of hitting a 2nd disk failure during a rebuild of the parity was pretty near 1 on large storage arrays some time ago...

Amazon stretches working life of its servers an extra year, for AWS and its own ops

John Riddoch

Re: "servers have a useful life of five years"

There are a bunch of reasons to replace servers:

Harder to get hold of replacements. No-one's making 5 year old CPUs as a rule (although I daresay AWS may have contracts with Intel/AMD etc to supply CPUs for a longer period) so maintaining a big enough fleet of server type A becomes too hard and you have to retire them and replace with server type B.

Technical debt - keeping your stack running on old kit means one more piece of tin to support so you have to retire it as new kit comes in and replaces it.

Marketing - if your cloud is using 5 year old CPUs and competitor is using 1 year old CPUs, which cloud are you going to use?

Power/cooling. New CPUs are often more efficient than older ones, so there are cases it's worth replacing old CPU models with newer CPUs. They probably don't have a much higher clock speed (if at all), but probably have higher core count so you can gain significant savings in footprint, power and cooling with newer CPUs.

As for impact on life of running in the cloud, I'd imagine they're mostly running hotter all day than on-premises kit; I don't know if that impacts their running life more than the warmup/cooldown cycles of on-premises.

Re: Its an alternative to doing anything useful

I have said it often - some people in America would vote for a dead goldfish, provided it was standing under the correct party. Sometimes it's because they've always voted Republican/Democrat, sometimes it's just because the goldfish wouldn't be the "other person".

Google Cloud started running its servers for an extra year, still loses billions

John Riddoch

Re: Old kit

There's a cut-off point at which you're better replacing older servers because the hardware cost is made up pretty quickly in reduced footprint/power costs. If you're running 6 year old servers with 6 cores/socket, you can probably half your running costs with a newer 12 core CPU because you'll get twice as many cores in each rack.

For a standard company, you often have to reckon in the project costs of doing such a replacement and getting budget approvals etc, and that's before you potentially get into licensing issues with replacements. If you're used to simply swapping out boxes on a daily basis and your software stack is free/internal, it becomes a much cheaper option to replace old kit, so that breakpoint of saving money happens sooner.

When forgetting to set a password for root is the least of your woes

John Riddoch

similar...

While at university in the mid 90s, my mate and I were doing some work and needed to FTP a file to/from one of the servers, so we opened up the supplied FTP client (stored on a Novell fileshare IIRC), typed in the server name and found an auto-completed config set for that server. With the root account. And a password saved in the config. We looked at each other and hit "connect"... and promptly had an FTP session on the server as root.

After confirming we were definitely in as root (by downloading, deleting and re-uploading /etc/passwd - yes, a bad choice in retrospect, we could have FUBAR'd the machine), we decided we'd better tell the lecturer who looked after that box about the issue. The config in the FTP client was removed that day.

Linux distros haunted by Polkit-geist for 12+ years: Bug grants root access to any user

John Riddoch

Re: Eyes

Why do we care about this bug that allows a user to run unprivileged code? It couldn't possibly be used to do anything nasty...

The point is that once you have an unprivileged shell on a target machine, having a method to escalate to root is the next step. The best crackers don't rely on one vulnerability, they chain together multiple vulnerabilities to get where they want to be.

Former Oracle execs warn that Big Red's auditing process is also a 'sales enablement tool'

John Riddoch

Handful of reasons:

1. Legacy. 10 years ago, if you wanted a robust, vendor supported DB solution, Oracle was one of the few shows in town. This makes for a lot of systems deployed on Oracle

2. Inertia. Once you have 100s of DBs on Oracle, it's harder to introduce another one. Many companies will have a policy like "all databases to be Oracle" because they've standardised on it.

3. Features. Oracle does have some features that are rare in other products. Probably >95% of DB use cases will never use any of those features, but if you need feature X, you really need it.

4. Application vendor support. "We support our application with Oracle DB" means you pretty much have to deploy Oracle if you want it to work. For some of these applications, there may not be a replacement which supports PG/Maria and is "good enough".

I strongly suspect that 90% of Oracle databases could well be managed with PostgreSQL, MariaDB or whatever quite happily with negligible development work, but the legacy and inertia issues mean they're stuck on Oracle.

Saved by the Bill: What if... Microsoft had killed Windows 95?

John Riddoch

Oh, yeah, the 6 monthly reinstalls were painful, but better than the instability & slow downs you got after a few months. XP was the first version which I managed to leave for over a year between reinstalls I think.

As for shenanigans with autoexec - my first PC (DOS/Win 3.11) had to have the boot interrupted to run Doom, otherwise it didn't have enough memory (a measly 4MB). I have vague recollections of tweaking both files at different times, but generally just left them well alone as far as possible...

LG promises to make home appliance software upgradeable to take on new tasks

'Admin error': AWS in dead company data centre planning application snafu in Oxfordshire

John Riddoch

Re: Rather close together

Latency and the speed of light. Basically, AWS runs "Regions" (e.g. eu-west-2 is somewhere around London) in which are multiple "Availability Zones" (i.e. data centres). If your data centres are too far apart, you'll start hitting latency issues with certain services which replicate data within a region, so you need to keep them relatively close together to remain performant.

As you've rightly pointed out, this does entail keeping them in the same "blast radius" of certain events which is why you should be looking to have a DR solution in another region to cover for the rare cases of an entire region going out. That said, the more common event is a networking/maintenance SNAFU which takes out a region rather than natural disaster.

Re: Authorised dealers only...

It hasn't got to that yet - turned out it wasn't a fuse issue anyway, so lost interest in tracking it down. Google searches weren't much help either, tbh, as there are so many different models of Passat. If I need to figure it out later, I'll dig a bit more.

Authorised dealers only...

Not quite as bad as the Merc, but my VW Passat manual doesn't even tell me which fuse is which. Literally, if a fuse goes, I'm expected to take it to a garage so they can charge me to change a part that costs less than 10p.

Heart attack victim 'saved' by defibrillator delivery drone*

Re: Doctors...

I've done some training on AEDs as part of First Aid at Work training and I was shocked (pun intended) at how simple they are to use. I've not seen one with videos, but the diagrams on the pads make it easy to know where to put them and the device will tell you what to do.

Also, as far as CPR goes, if someone isn't breathing, you CANNOT make them worse by attempting CPR. At worst, their corpse might have a few broken ribs (common rule of thumb is "if you don't break a rib, you're not doing it hard enough), but they'd be dead anyway. At best, you'll keep their organs oxygenated long enough for medical attention. Bad CPR is better than no CPR.

Re: Coding, Sigh

Ah, I must have been thinking of return codes in Unix shell scripts... Like I said, it's been a while. The last real C programming I did was when I munged the XMMS Solaris plugin but that was about 20 years ago.

John Riddoch

Re: Coding, Sigh

One = mean assign, two means comparison. As to why that was done way back when, I don't know for sure. It does mean that both of these are valid in C although they behave differently (in most cases):

if ( x = y ) // assigns value of y to x, checks if that is true or false (true=0, false anything else IIRC - it's been a while)

if ( x == y ) // compares x to y, doesn't change value of either

The fact that the top option works and will compile must have been the source of millions of bugs in C programs over the years. I will note that, for my sins, I have used the method of assigning a variable in an "if" statement intentionally (in Java, FWIW, although the methods are the same) and the code worked as expected.

Normally, if two insurance policies cover an incident, both pay out a portion of the payout.

What happens if both say the same thing would be interesting as you could argue neither apply...

Google advises Android users to be careful of Microsoft Teams if they want to call 911

John Riddoch

Re: Good old Microsoft!

It's probably down to how you can register other apps for core services - like FB messenger keeps nagging and trying to take control of SMS messages ("Unified interface for all your messages", totally unrelated to slurping up as much data as we can for advertising...). It's potentially really useful to have an alternative app for making phone calls (possibly with accessibility features for some users), but that application must NEVER interfere with making emergency calls. It should also be crystal clear that it's taking on that role so the user understands what's going on.

Best guess is that the issue is Teams app trying to register as a way to make/receive calls (since you can make calls with Teams) and screwing it up.

Re: My email wasn't blank...

Use of Amex is still flaky; a lot of stores don't accept mine so I have to use another card. Annoying (particularly as mine gives me cashback on purchases), but I just shrug and pull out another card.

Visa/Mastercard pretty much have a duopoly on card transactions, so it would be interesting to see if Mastercard start ramping up their fees too where shops would go after that.
