Agile Manifesto co-author blasts failure rates report, talks up 'reimagining' project

Re: The more process you have the less agile you are.

So much this.

In one place I worked, the top management were sold on the belief that you implemented all Agile framework [X]'s principles from A..Z and the world was suddenly a wonderful place.

When, for example, I queried the need for a team of 6 engineers *who sat right next to each other* to stand up for 15 minutes every morning to tell each other what they were working on (which often ended up as 45 minutes of two of them debating some technical issue while the others twiddled their thumbs), I was all-but denounced as a heretic.

Tesla Cybertruck turns into world's most expensive brick after car wash

Not a unique issue

My car (2010 vintage) also has a car wash mode - it's called "Tuck in the wing mirrors and flatten the roof-mounted antenna".

Sheesh, that Tesla boot time is slower than my homebrew 4MHz Z80 machine starting CP/M from an Hitachi 4GB Microdrive.

Google's AI-powered search results are loaded with spammy, scammy garbage

Re: Total garbage search results, even for simple tech search terms

DDG's search results are going downhill too; which reflects mostly on their sources.

No shit sherlock

The results from all the major search engines have been getting progressively shittier for several years.

I am sure Google:

Values the quality of its search experience very highly.

Always endeavours to provide only the best, curated search results.

And lots of other marketing crap including words like: 'strives', 'synergy', 'quality' and 'listens'.

But we're living the reality of the situation - and it's dire.

Never mind, those profits still look oretty good for the shareholders.

Microsoft license shuffle means Power Apps users could break the bank

Re: Very generalised response ahoy

Yep - good poiint. Corporate politics and evangelism come into play too.

My background is very much biased towards Linux-based platforms and Open Source stacks.

Last place I worked spent a fortune on commercial middleware and development to integrate a couple of ITSM tools with SolarWinds, mostly for CMDB ingest and updating. I knocked up a proof-of-concept analogue in Fusion Inventory and Node-Red etc. in about 2 days as a side project to fulfill a similar, but different need, but the grown-ups couldn't get their heads around the 'L' word.

Very generalised response ahoy

I know it's down to needs and use case, data volume, responsiveness etc. etc. but I implemented a data collection and dashboarding tool with Node-RED, InfluxDB and Grafana. Picking up data from sensors (low bandwidth MQTT), Webhooks, JSON formatted data streams, API calls and some Direct (IP) device probing.

It's not a very sophisticated stack but it did the job and avoided PowerApps completely.

Brit broadband subscribers caught between crappy connections and price hikes

Datacenter fire suppression system wasn't tested for years, then BOOM

The newly-installed fire suppression system in the computer room next to me was test-fired with a cylinder of CO2.

That's when the contractors found the uncoupled pipe in the false ceiling - mostly because the entire ceiling, dust, metalwork and all, was now resting across the floor and the IBM mainframe, while the air in the room was doing a good impression of the smoggiest day in history.

At least all personnel had left the room for the test. The cleanup bill was expensive because as well as replacing the entire ceiling, the mainframe had to be cleaned and all dust filters changed. Fortunately, no asbestos found.

Son of a 'b'

Back in the early 90s, the place where I worked ran Sage Accounting on a system running AT&T UNIX.

Our semi-technical Financial Director was doing some housekeeping and needed to restore a copy of the bought ledger files from tape. As was Sage's way of things, all the bought ledger files started with 'b'. Unfortunately, the FD restored all the files into the root folder, so he just moved 'b*' to the right place and carried on.

A month or so later, the system was restarted but failed to come up. A bit of head scratching and a pile of 5.25" 'recovery' floppies later, we discovered that a rather critical file called 'boot' had been swept into the bowels of Sage alongside the bought ledger files.

DIY Sinclair clones: Left it too late to back the Next? Build your own instead

CP/M Systems

Back in the 1980s, as a very young electronics engineering apprentice working in an R&D lab, I was tasked with operating and maintaining the lab's timesheet recording app, which was hosted on this big (small filing cabinet on its side) 'thing' with twin 8" floppies. It might have also had a hard disk, I don't remember. The program was written in BASIC and I didn't really think much of it at the time.

When I got back into the retro 8-bit scene a few years back, it dawned on me that the system was a Cromemco, probably sent over from our US parent company! I suspect the system was replaced with a PC eventually and the Cromemco hardware was probably scrapped for parts :-(

Start or Please Stop? Power users mourn features lost in Windows 11 'simplification'

Win 10 treacle mode

Likewise, just for one app that runs a chip programmer.

I always regret it though because the first thing Windows does is start doing updates, slowing the entire computer to a crawl (Core i7 @ 3.4GHz, 16GB RAM, Enterprise-class HDD; might change for an SSD).

Sometimes it's around 10-15 minutes before the machine is useable for browsing, email etc. I often spend perhaps 10 mins with the app and then reboot to Linux.

It's a traumatic experience every time.

The Novell NetWare box keeps rebooting over and over again yet no one has touched it? We're going on a stakeout

Oh the memories...

When Netware 386 3.0 came out, I had a nightmare server on a customer's site in London (my office was in West Sussex).

To cut a long story short...

Regular trips to site to try and catch the issue. Very stress-inducing customer.

Replaced components until the server was effectively swapped out - apart from the case.

Novell took an interest on the basis that it might be a software glitch...they found an issue with the 'network cable disconnected' code...but the server still crashed maybe 2-3 times a week. Nothing else in the server room was playing up.

I tried a mains analyser - nothing stood out except perhaps the odd 'blip' at crash time - but it was barely more than a bit of noise.

Widening the search for a fix, I asked about the room, which belonged to another company, behind the server room...it was their kitchen, and hard up against the wall behind the server was their dishwasher. It turned out that the dishwasher was switched on when full..a couple of times a week!

Hey - EMP from the some motor or pump in the dishwasher knocking over the server!

Fix: Move the server to against another wall.

Western Digital shingled out in lawsuit for sneaking RAID-unfriendly tech into drives for RAID arrays

Um, no. Not quite.

Hitachi Global Storage Technologies was created by an IBM/Hitachi drive tech business merger in 2003.

WD acquired the business in 2012 and rebranded it as HGST and from that time, it had absolutely nothing to do with Hitachi.

WD does not own Hitachi.

Re: for the cost of a tape to copy them to and delivery.

At one place I worked, the in-house facilities guys turned one end of an office block into a fully airconned computer room with raised flooring:

1) They boxed-in a row of radiators behind drywall - but didn't shut them down, so from the getgo the room never reached the expected temperature. The aircon guys spent ages recalculating things, checking equipment etc., before someone commented 'does this wall seem warm to you..?' Out came the padsaw, holes were cut and valves were turned. The room temperature dropped, but the ugly holes were never fixed.

2) They put the room stat on a pillar next to a window so it was affected by outside temperature and sunshine. The room went into superchill mode when the sun was shining, and on very cold days the aircon would hardly kick in and the room stayed toasty. When someone put 2+2 together, the stat was relocated.

Support: Oh, the driver'll be on the CD..

Me: See my problem here?

Support: Um, yeah - but the driver will be downloadable from the BBS too...oh, yeah.

Me: I'll just pop back to the office and fetch stuff on a floppy or three..

Support: Hey, if the server's hooked up, why not download the drivers on another machine and copy them across the network?

Me: There's no other machine here with a modem. Anyway, Would the NIC drivers be on the CD?

Bloke launches twinkly range of BBC Micro:bit accessory boards

Re: “I’ve designed my own connector,“

Edit: I see Gaz was onto this and has revised the article text.

I think what Nevil meant was that he's designed his own system/connector to mate with the pitch of the edge connector on the micro:bit - and in that respect he's dealing with what pitch the micro:bit designers chose and not numptyfying* anything.

2 FWIWs:

When the micro:bit first came out, getting hold of ANY compatible edge connectors (or even the spec for one) was a PITA until Kitronik et al started to make them available.

I have been playing with a few pre-production samples of Nevil's boards for a while - kudos to him for the effort put into the project.
