Good evening everyone 

 

I managed to sort out the bathroom light pull without resorting to replacing the cord. It wasn’t as simple as re-threading the cord though. The light pull had 2 rubber washers, one at each end, these had perished and it took quite a while to remove the last traces of the old rubber. However, the threaded rod that passes through the handle was too long, so I needed some new washers, luckily I was able to get away with making only one from placticard. I then re-fitted the light pull, re-threaded the old cord, tied a knot at the end and it was job done. 

 

I then spent the rest of the day playing with my DCC controller and an accessory decoder. I’d originally planned to use these to operate all the points. But with such a big layout, remembering all the point numbers would have been a nightmare. They wouldn’t work with servos either, so I changed direction, but ended up with a dozen or so decoders with nothing to use them with. So I’ve been experimenting with LEDs and small DC motors. By making adjustments to some of the CVs I can switch LEDs on or off and run a DC motor, either continuously (not very practical) or from anything from 20 milliseconds to 5 seconds, infinitely more useful. I can also change the direction in which the motor runs too. So, if I design and build a small gearbox I could possibly open and close loco shed doors, crossing gates etc, something to think about.

... as outlined in earlier posts, the search for Sony’s much sought after games console again proved fruitless. I note the comments of some on here about “marketing”. I have been involved with buying consoles for over 30 years. There are always issues with supplies of any brand new games console. They simply cannot make enough for the demand. The pandemic has certainly made things worse in terms of supply and the ability for customers to order them.

Sony cannot source enough of a processor chip from AMD designed for the PS5. The AMD CEO is on the record saying that she expects shortages through the first half of the year. See this news item.

 

Today, AMD is a fabless semiconductor company, meaning it uses wafer fabrication from suppliers like TSMC. There is a global shortage of semiconductors, including in the smallest (most dense) geometries like AMD is using for the PS5 chip. The shortage has also hit the global automotive industry (even though, generally speaking, automotive electronics don't rely on the latest wafer fabrication nodes) and many automobile manufacturers are limiting production because they can't procure enough electronics devices.

 

It's not just demand. Wafer manufacturing has become incredibly consolidated. There used to be dozens of companies doing "leading edge" manufacturing. Now the list of truly leading edge fabs is down to TSMC and Samsung* and few others. A number of things are driving this:

  • It is staggeringly expensive to set up the newest high density nodes
  • It's also technically difficult
    • (Intel, which still does manufacturing and was at one point the world leader is struggling to keep up, even though it is still number one in revenue)
  • Market-driven M&A activity is also driving consolidation

* Combined, TSMC and Samsung represented 72% of the global semiconductor foundry market in the fourth quarter of 2020.

I remember in the early '90's memory chip prices doubled due to a fire in a Japanese factory that supplied the glue needed in memory chip production.  An extract from The NYT of August 1993, prices and memory sizes would seem quaint to the kids of today with their phones full of 8GB of RAM...

(I remember paying around  $700 for 16MB of RAM at an NEC auction here around that time):

 

HERE we go again. Prices for computer memory chips have doubled in the past month, touching off a panic among computer makers and raising the possibility that computer prices will rise -- or at least stop falling for a while.

Sharp price swings are nothing new to the memory chip business, perhaps the most volatile of computer component industries. Prices more than quadrupled in the late 1980's and then reversed direction to become cheaper than ever in the early 1990's.

 

"We're back in those wild times," said Mike Frost, chief executive of Tech Works, one of the leading vendors of dynamic random access memory chips. A few months ago, the cost of a 4-megabit memory chip was $10.50 or $11 on the spot market, Mr. Frost said. Last week, it was about $20 and heading north.

So computer owners who had become accustomed to inexpensive upgrades, often as little as $150 for 4MB of additional memory, may soon see prices climb to $250 or $300. 

 

The episodes are reminiscent of the last chip panic, in the late 1980's, when a 4MB upgrade might cost $2,500 and it was not uncommon for companies to remove memory chips from inactive machines and lock them in a safe.

 

The catalyst for the recent panic was the July explosion at an obscure but important factory operated that is the world's leading supplier of a kind of epoxy used in the packaging of memory chips. Some 60 percent of the world supply of this esoteric goop was produced at the plant, which Japan has vowed to rebuild quickly.

 

The panic was easy to set off because demand for memory chips had been drifting upward before the explosion. As computer prices plunged in the summer of 1992 through the first half of 1993, PC customers chose not to pocket the savings, but rather to set their sights higher: on powerful Intel i486-based systems that could run Microsoft Windows, I.B.M.'s OS/2 and other so-called graphical operating systems. Those require at least 4MB of system memory. So the PC makers raised the base configuration to 4MB. (A megabyte is approximately 1,000 kilobytes, or the equivalent of a million alphanumeric characters.) Lately, some personal computers have been introduced with 8MB or even 16MB of base system memory.

I was a Fortran programmer for my working life. It suited our pension calculations and the actuaries could follow it.

I could never get Basic programs to work. COBOL looked like wriring an essay.

I tried learning C but I kept getting stuck with "C can't do that; you need to write a subroutine." and that would be just something like input/output.

In fact, the ERP system that I work with, until the latest release about 2+ years back, was very COBOL-based, using a hybrid of COBOL code, since the system was first developed in the mid-80s in COBOL on IBM mainframes. All easily migrated through the various generations of systems.

 

I wonder if that is the ERP system our organisation was using when I retired 13 years ago. I would give you the name of it, but it caused me such grief that my mind has genuinely suppressed it! We had so many 'bolt ons' (processes written by ourselves to handle all our users' peculiar 'needs') that any new release of the ERP required massive amounts of testing on our part - so much for easy migrations.

 

But at least it wasn't SAP.

For many years DRAM was used as a sort of 'barometer' for the semiconductor industry and it was usually the first application for new technology nodes since increased density led to cheaper memories. The memory market was always volatile. Perhaps 40 years ago, Intel shifted it's focus from DRAMs to microprocessors to lessen the impact of memory-related business volatility to the company.

 

Today there is less emphasis on DRAMs in proving new processes. FPGAs are more likely to be the class of device for proving out new nodes. AMD announced that they would acquire Xilinx, (the largest FPGA company) in 2020. This acquisition surprised many and is not yet complete.

Morning all,

Sorry I haven’t been around lately, but I collapsed at my desk with a severe attack of GAS* and was rushed to the company’s medical centre. Things were looking grim, then they called in a DoB** specialist who prescribed me this:

A few bars and licks later I was discharged without sequalae.

A full recovery is expected.

Expect commentary on posts later today

Well half an hour into being awake, and although a bit gloomy outside, all is fine inside.

 

A great day yesterday doing some more Videoing on my M.... R.......... L....  which I will only talk about on my M.........ing Thread so as NOT to upset the Awl injector.

 

Life is good and no complaints from me.

 

Have a good day one and all, stay safe and keep well.:good:

Another dull and grey morning in North Somerset. A couple of parcels arrived yesterday, containing summer bulbs, but the showery nature of the day kept me inside. 

 

Even after 6 weeks of wood pigeon plastic spikes around bird food, one idiot bird is still trying its luck thinking something might have changed overnight and the food suddenly is reachable. Every time it is frustrated and then goes and sits on the hanging feeder pole which discourages smaller birds. 

 

Is there any wonder that wood pigeon is now top of the BTO garden bird list, as the one reported in the most number of gardens?

Morning all.

Overcast with showers here so far. Fortunately I am not going anywhere. My toothache needed something slightly stronger than paracetamol last night but it isn’t too bad this morning, perhaps the antibiotics are working already. 

I will be in charge of receiving the shopping delivery today. Aditi will be attending via Zoom a post-funeral prayer for her Aunt who died earlier this week. The cremation happened the next day.

Zoom has been a great help during the pandemic. My ex-wife's 50th yesterday. A friend arranged an online cocktail party on Zoom.

Morning all from Estuary-Land. Stiff joints this morning but they soon unstuck and Arthur Itis was only present in his usual haunts. A brace of paracetamol soon put him in his place. I've only had the stiff joints since I had the jab, I wonder if there's a connection?

Bear recalls going to work one day in the early 1990's to be confronted by numerous (15+) p.c's with lids removed - someone had helped themselves to the memory chips apparently.  This was in a place where such things shouldn't have been possible....  I never heard any reports of guilty parties being identified.

 

About the same time we were having a new server installed at work. Then one night the place was raided, three members of staff were tied up and the server stolen. We never heard of any outcome, there were no arrests. The suspicion was that it was an inside job.
