Static electricity can be shockingly funny, but the joke's over when a rack goes dark

Dvon of Edzore

Re: noise. Or the lack of it.

A much smaller DEC, in a filing-cabinet-sized rack, was installed in an attorney's (barrister's) office suite. This was a new business series intended for such uses. The fans were quite effective at keeping it running, but did not fit in with the character of the surroundings. Normal abatement efforts were unsuccessful, so the senior attorney contacted an executive at DEC. The executive, oddly enough, went down to the shop floor, listened to an example of the unit in question, and replied "That's unacceptable. I'll have a tech there to replace them with quieter fans very soon."

In the fullness of time, a tech with a couple of brown boxes appears and installation of said new fans begins. Unfortunately, a Murphy demon also arrived and a wire slipped from its usual place to brush the CPU board. The other end of the wire, as you have guessed, carried voltage and currents suitable for destroying business computers. Imagine upsetting sound effects and smells. The Murphy demon's friends in the DEC warehouse then hid all the matching CPU boards so what had been a nice bit of slightly-noisy kit remained expensively silent until a distant assembly line came round to building that board again.

The secretaries transcribing dictation tapes appreciated the quiet, at least.

Global datacenter electricity use to double by 2030, say policy wonks. Yup, it's AI

Tyrannical Government Wanted

AI demands more electricity, say global policy wonks. Generating more electricity will destroy the planet, say other policy wonks. Governments who listen to the rabble, who listen to the wonks, give speeches and otherwise do nothing. The solution is clear.

A government is needed where one person controls devastating force, one person who is free to dispose of both wonks and rabble at whim, who feels no need to be either fair or reasonable. It is time for Lord Havelock Vetinari.

Huh? My MPU-401 worked before there was a Windows. Meanwhile, the rest of the world is using Ethernet-based audio routing protocols like AES50, AES67, Dante, Livewire, RAVENNA, and others designed in THIS century - working across the stage or across multiple oceans. Even the stage lighting moved past slow protocols like MIDI a long time ago.

Often the founders find that running a business is not as much fun as creating and growing one. They then get offers that will finance their next idea and soon hand over their child to these devils in angel's clothing. Those who only look ahead never see the burned-out husks of the companies and people they leave behind.

Re: "Passivated" I understand, but "fully demised"?

These are both Government Regulatory Body terms. There are a lot of ways an object in space can be "dead". The new hotness is to ensure an object that re-enters Earth's atmosphere turns into small particles that are no longer of interest to anyone that matters. Thus "fully demised" meaning not on orbit and not in big enough pieces for government to care about.

Raspberry Pi sets IPO jam for June

Dvon of Edzore

Re: Carving up the Pi

If this were simply an industry grant with very limited strings attached, or a government incentive to build a new factory in a disadvantaged area, I might agree. Going public means business decisions will be made in the interests of the shareholders. No longer shall the lofty goals of the founders be echoed by strong community support, which has been the continuing value behind the Raspberry Pi. Now quarterly profits will determine both sales allocation and new product development. Rumors in The City and at other stock exchanges will drive short-term thinking, to the usual disastrous results. "Continue their outstanding work" shall be relegated to an increasingly inaccurate marketing phrase.

Carving up the Pi

What we see here is the Upton's retirement plan. It's no longer fun to operate a small, agile, and focused organization designed to bring new people into STEM education. Building the parts that go invisibly deep inside other products brings in both the money and the ulcers. Better to unload the whole thing on other suckers while they still have some positive press to squander.

No one can serve two masters. RasPi will now be under new international governance at the whim of whatever cause gets the publicity. Goodbye, Raspberry Pi!

It's who counts that counts

The two biggest examples, financially, of intellectual property are the music and film industries. In both, the accounting department is the main profit center. By "properly" identifying expenses, any given product can be shown to have occurred at a loss and thus generate no profits to be shared with lesser entities like actors, musicians, and programmers. Superstars who can negotiate contracts to be paid "above the line" are rare for a reason. And as the unions are quick to point out, there is always someone willing to work for nothing unless prevented.

Seriously, good luck with this.

Want to keep Windows 10 secure? This is how much Microsoft will charge you

Dvon of Edzore

Re: Go to market strategy

That is precisely the case, and the title of this article reflects how well their strategy has worked. Want to "keep" Windows 10 secure? That presumes Windows 10 is currently secure. It is not now, nor has it ever been. Microsoft's greatest trick has been redefining "secure" to mean "continually modified." Ironically this exists simultaneously with the meme that the monthly patches will break something, and that Patch Tuesday is just the start of Remediation Week, Workaround Month, or the Year of We Can't Do That.

The current churn cycle of Announce Upgrade, Ship, Test, Fix, Repeat produces exactly what it was designed to: a demand for full replacement (at a hefty profit) of the now enshittified product as rapidly as the consumers can be forced to do so. We can only comply as the Standard of the Industry falls lower and lower with each iteration.

Truly secure software is produced by quality-minded people who are allowed to do quality work in an environment that maximizes enduring quality. Software that leaves the vendor in a secure state cannot, by definition, be rendered insecure by external developments. Packets do not magically get higher voltage over time to batter through aging firewalls, nor does payroll software gradually forget that Hours * Wage - Deductions = Paycheck. Only improperly modifying the internals, such as with poorly-tested patches, can render working software insecure. Pity THAT isn't common knowledge.

US reckons it's about time the Moon had its own time zone

Dvon of Edzore

Re: Surprised it's only just come to the fore.

Lunar science, and space science in general, has an excuse that previous missions were so short, horologically speaking, that any relativistic differences in time were completely swamped by propagation delays and, in the case of deep space probes like the Voyager series, Doppler effect on radio frequency. Now that longer duration missions are being planned such that specific locations on the surface will matter, the precision timing requirement of satellite-based location measurement comes into play. A moon-based Coordinated Lunar Time network has become necessary and practicable only recently.

Backblaze's geriatric hard drives kicked the bucket more in 2023

Dvon of Edzore

From previous blogs I understand Backblaze waits to replace drives in a storage pod until a certain number of drives in it have failed. The coding scheme used for their multiple drive redundancy permits normal operation with several drives failed in each 20 drive RAID set. That way the power cycling and other costs of pulling a pod from operation can be spread across multiple drive replacements at a time. Each drive in a set is in a separate pod, so if a whole pod goes down, whether from maintenance or system failure, it only takes out one drive from each set, and operation can continue using the remaining pods.

If a set has more than a couple of drives in failure state, the data is migrated to a different set before enough fail to risk data integrity. This allows waiting to replace drives in their 45 or 60 drive pods until it is cost effective to do so. Their massive numbers of active drives, and the design to manage them, gives Backblaze additional flexibility most small organizations don't have.

Re: And the valves?

Although digital proportional valves have long existed, continuously-variable flow can be simulated with on-off PWM to any degree needed. Designing for PWM also allows much faster response to changing conditions than existing mechanical systems which are high-inertia, slow-moving beasts.in comparison.

As others have already noted, the fine article says manufacturers will be free to provide their own crapware, sourced from their own servers. However we both know the next thing will be under-the-table encouragement for makers to stop doing that in favor of the "universal" solution, which locks users into whatever the cartel decides is most profitable. After that comes bankruptcy or merger of the weaker cartel members into the stronger. Eventually a sole source for printing emerges which appears immune to anti-monopoly laws, but speculation there is a government back door involved somehow never gets printed.

Don't be so surprised

Circa 1980 I was involved with an early computer retailer. An accounting package was offered by a vendor, which supposedly ran on systems we sold. It had been written in BASIC, and used the factory-standard interpreter. (It was a different time, OK?)

Within the first CRT page of code was a line that caused the product to crash. Unconditionally. The as-distributed copy had no way of ever running.

Fixing that, and upon examination by someone with bookkeeping clue, the columns of numbers didn't add up. Somehow they were printing the detail of credits and debits in the wrong columns, but the totals were in the standard locations. Checking the example reports in their printed marketing materials showed the exact same little oopsie.

Phone call to the software supplier went as expected. "Our product is perfect, you must have a bad computer, you did something wrong, this software is in use daily by hundreds of satisfied customers..." You know, the usual blaming of the victim.

The software was not offered to our customers, nor did we offer a contract to repair it. Oddly enough it avoided becoming a well-known accounting product today.

Datapoint (maker of ARCnet) had an accessory optical link to get around needing to pay telco to run a wire across a street or paperwork for government-licensed radio links. It was plain optical with big lenses to avoid cost of compliance with laser safety regs at the time.

https://en.wikipedia.org/wiki/Datapoint_2200

Expanded summary:

* 8008/8080 came from the Datapoint 2200 design, not the calculator-based 4004.

* As reported in other accounts, the 2200 design was offered to both Intel and Texas Instruments in order to pay an overdue bill for memory chips. Intel accepted, TI refused.

* The improved instruction set of the upgraded 2200 became the Zilog Z-80 when Intel decided the original was good enough. Some Intel engineers thought otherwise, left and formed Zilog. The two instruction sets were essentially identical, even at the bit level.

* The 2200 was an early all-in-one computer, having keyboard, screen, processor and storage (a pair of digital tape drives) in one desktop box.

* The display on the 2200 was a pioneer of human factors engineering. The screen refresh was synchronized to the power line so office fluorescent lights reflecting off the screen no longer caused flicker-induced headaches for the operators.

* Datapoint also pioneered heterogenous networking in Arcnet, where multiple computers could share a single hard drive. (Was this the first SAN?) The interface also supported hardware encryption via a plug-in scrambler PROM chip, which allowed different users to have private repositories on a shared drive. I saw all this in operation with a software development team. Each programmer had their own chip to encode their work.

* Arcnet also had a wireless link over non-laser, non-radio infrared optics, so it didn't require FCC or AT&T permission to cross a public street within a campus, as wired or radio network links would at the time.

* The Datapoint OS also allowed rudimentary multi-tasking. For example, one could play a game on the screen while copying one removable hard disk to another.

Not bad for the early 1970's!

Re: Floors?

At my university, the building mainly housing the Computer Science department had a lobby with a parquet floor which the IT students installed. (The floor may have been their gift to the school - those neurons were recycled decades ago.) After inserting the final piece of the puzzle, the tired crew went back to their dorms, only to return the next morning to a veritable explosion of small wood squares. It seemed the kiln-dried lumber had made merry with the rise in humidity overnight and expanded a bit in size, but the walls were not so forgiving. Reportedly, the student crew had to hand-sand each of the thousands of squares to make them fit once again. (I suppose the grain of the wood made them no longer square so the pattern wouldn't work if used as-is.)

Re: Its a partial description of your IT farm.

"I usually joke that if I'm doing my job well enough then I've just done myself out of a job because everything important is now covered and there is nothing really for me to add."

What you add is your current experience. You better understand the relationship of the components to the business, and can modify the monitoring and reporting to be more useful for your specific business case.

You can also work on cross-department relationships so changes can be anticipated and the infrastructure ready to meet future company goals as they arrive. For example, adding a first-ever third-party sales representative in a different country can bring a nightmare of compliance issues that did not exist before. You'll really appreciate time to get understanding and documentation of requirements and costs when you're blindsided in a meeting and have to either commit to doing something you have no idea how to accomplish or be seen as obstructionist to company progress.

Nestled between donuts and gingerbread creations lurks the Windows 7 EOS fairy

Dvon of Edzore

Spread it on the rose bushes

Microsoft is spinning a fairy tale. Windows of any version is exactly as vulnerable to viruses the day or year after support ends as it was the day or year before. Software does not "wear out" with use like a pair of cheap shoes. Internet packets do not get more powerful to break through closed connections like K.I.T.T. crashing through a wall. Defects in design or production that allow malware exploits were inherent in this "professional" software from the moment it left the factory, and should be treated by regulators the same as safety defects in appliances and automobiles - by mandatory repair or refund regardless of warranty terms.

An End-Of-Support date is just an attempt to turn liability for defects into sales of new products with new defects adding to the legacy defects carried forward for compatibility. Microsoft's shifting "end-of" dates testifies to how arbitrary these paper lifetimes really are.

The cycle of "sell crap, pretend to care for a bit but disclaim all remedies in the license, sell new crap" will continue until lawmakers assign strict liability to software vendors that claim to offer support as a justification for the price. If the license limit on number or type of installation applies in perpetuity, then so must the full support period. Flaws present from Day One should be treated as if they were discovered on Day One and not allow the get-out-of-hell-free card of calling a product "too old to fix."

Firmware for such devices is often shared among multiple related products, including those from other vendors, because chipset makers generally provide reference designs and code libraries for the purchasers to brand with their product logos and other user interface customizations. This was seen last year when a broad swath of Netgear home routers were found vulnerable to a common set of vulnerabilities, as cited in the story.

Searching the CVE database for the similar JGS524PE, one finds four 2020 vulnerabilities shared by the JGS516PE, JGS524PE, JGS524Ev2, and GS116Ev2. Someone having any of these four sibling devices should press Netgear for answers.

Sprinkler myth is all wet

All the sprinkler heads going off at the same time only happens in bad movies. Each sprinkler head has a heat activated trigger that keeps the water valve in each head closed unless the air temperature at that specific head rises above the trigger value. This system was designed a long time ago when elec-trickery was understood to be unreliable in a crisis, so no common signals for false alarm disasters.

Still a dumb idea to use water, when CO2 is cheap and plentiful. Too bad the horns that announce its release are so loud the vibration can damage the equipment (hard drives mostly) it is there to protect.
