  1. Prolog nezmizel. Jeho hlavní myšlenku dnes potkáváme v nástrojích, které se Prologu na první pohled nepodobají: v CodeQL pro analýzu kódu, v Rego pro policy-as-code, v Z3 pro práci s omezeními a v Leanu pro formální důkazy. Každý řeší jiný problém, ale všechny připomínají totéž: někdy je lepší popsat vztahy, pravidla, omezení nebo tvrzení než vrstvit další if.

  6. It is good to sometimes go back to the basics and hand assemble some prototypes. It took me about two full days to assemble and partially test these. When using the Pick and Place machine I can assemble about 1k units in that time 😭(it takes several days to set up the machine so it makes little sense for early prototypes, and I don't have them on panels anyways…) #microcontrollers #debugging #development #PCB #assembly #SMT

  14. oh here'a an old piece from august 2022

    i'd drawn this before soul hackers 2 actually released. i have very conflicted thoughts about that game - i think i was too out of the loop to know that this particular frost was locked behind a paywall, for one thing - but going back over my old work i'm surprised this one sorta holds up. ai-ho!

  19. I bought a #Hangell (no, I wasn't familiar with that name) switching bench power supply and it arrived. It happens to be one that #BigClive just briefly showed in one of his unbagging videos.

    I got it because my existing old #linear supplies max out at around 18 V, and that has been a hindrance of late. A #switching supply isn't ideal, because of the possibility of noise, but this model will do 5 A at 60 VDC, and a linear supply that can do a couple of amps at that voltage is big, heavy, and pricey.

    So of course, as soon as I received it, I took it apart. As you do.

    And ... I'm pleasantly surprised. The #PCB layouts look good, the assembly appears very good, with proper pick&placed #SMT components and reflow soldering, not hack-job hand soldering. The components seem to be #quality, even name-brand where appropriate. There are what appear to be genuine class X and class Y #safety capacitors everywhere they should be. The front binding posts are fairly typical cheap #Chinesium ones, but appear to be from the better end of the quality spectrum as far as those go.

    One ding: the multiple #electrolytic output caps appear to be 63 V-rated ones. For a supply that goes up to 60 V, that's just not acceptable. Maybe that's because this unit can also be had in a 30 V model? Or maybe they're just hoping you don't notice.

    I'm sorely tempted to replace them with 100 V-rated ones before I use it. I'm going to add some more output #filtering as well.

  20. When the Ballroom went to war: the thread about Portobello’s Marine Gardens wartime role as a landing craft factory

    Much has been written on the enigmatic Portobello Marine Gardens pleasure park, a short-lived leisure complex which opened in 1909 only to close in 1914 when it was requisitioned by the military for wartime use, never to open again.

    Postcard of Marine Gardens in 1909 showing the various buildings and entertainments, looking across the Firth of Forth to Fife. The 3,500 seat concert hall is the domed building in the middle right, the 1,000 place ballroom and roller-skating rink is the lower building on the right below it with the barrel-vaulted roof.

    Some of this story can be seen below in an old thread on Twitter from Portobello Library.

    https://twitter.com/PortyLibrary/status/1448604902968680451?s=20&t=royrHdQcpBrv3nsFxF0MWQ

    The operating company was forced into liquidation in 1916, unable to make any income and still liable for rates and taxes. After the War the city Corporation bought and cleared most of the site, but some was bought by local entertainments entrepreneur Frederick R. Graham-Yooll who refurbished and re-opened the grand ballroom (half the size of a football pitch and one of the largest in Scotland). This would become one of the most prestigious and popular in the country.

    The interior of the ballroom in 1912 in its glory days. A big open space with no obstructing roof supports, as good for building bus bodies as for dancing in. Edinburgh and Scottish Collection, Edinburgh City Libraries.

    War intervened once again in 1939 and the venue closed its doors again when it was at the peak of its popularity, the last dances being advertised in the Edinburgh Evening News for the coming week on Friday September 1st. Once again the military moved in, troops of the Kings Own Scottish Borderers being billeted there and entertaining the locals at the adjacent football stadium, playing as the Edinburgh Borderers. The venue saw occasional use for concerts organised to entertain servicemen or public displays of military or civil defence drills at the stadium. Valuation rolls for 1940-41 show that the site was owned by the “Trustees of the late F. R. Graham-Yooll” but much of it occupied by the War Department.

    Around that time (probably late 1942) the Scottish Motor Traction Company – universally known as SMT – took over the ballroom for use as a coachbuilding works. This company was a vast conglomerate that spanned Scotland and had its fingers in any number of pies. It ran a significant share of the country’s public bus services outside of the main cities and much of its long-distance coaches; it briefly ran an airline, was at the forefront of the motor trade and had its own in-house coachbuilding operations making bus and coach bodies for its fleet. In the below aerial photo of 1962 the barrel-vaulted roof of the old ballroomcan be seen surrounded by later additions. To its east is a large new works, the Marine Garage of Edinburgh Corporation Transport.

    Zooming right in, you can even still read the ghost sign of “Marine Gardens Ballroom” on the front, 23 years on from its closure.

    An advert in the Sales by Auction listing in the Scotsman on 6th August 1942 gives a possible date for the takeover of the ballroom:

    Monday 10th August at 11… Within the yard of Messrs. Adam Currie & Sons, ltd. West Saville Terrace. Ballroom and Restaurant Furnishings, Removed from The Marine Gardens, Portobello

    Everything was up for sale, from tables and chairs to couches and settees all the way through to cigarette vending machines, chip slicers, champagne glasses and a ham-slicing machine!

    In addition to taking on and expanding the old ballroom, SMT extended the operation on vacant land to the west on behalf of the Admiralty – who paid for 87,200 square feet of modern factory buildings to be constructed. Here they built some sixty Bedford OWB Utility bus bodies here with no aluminium (which was a strategic material for the aircraft industry) and with austere bodywork and finishes for economy’s sake and also undertook work for Edinburgh Corporation Transport.

To its south, the old speedway racing dirt track is noted as a “test track” where vehicles exiting the works could be given a shakedown drive. Reproduced with the permission of the National Library of Scotland

    But the Admiralty wasn’t interested in buses. Why then had they gone to this expense then? The answer lies in the map and on the below photograph – if you look closely you can see that there was a slipway leading from the works, across the beach and into the Firth of Forth.

Notice the slipway extending across the shoreline in the middle of the shot. SAR031664 via Britain From Above

    Buses don’t need slipways, so what was one doing here? The answer is that the Admiralty did not want SMT to build buses, they wanted them to engage in war work and were build amphibious landing craft! Marine Gardens was a purpose-built site for the production of the Landing Craft Assault – better known as the LCA.

    A factory fresh LCA on a trolley for moving it through the factory of Harris Lebus Ltd. in Tottenham Hale where it was built. You can see the diagonal pattern of the teak planking, and the riveted, rectangular panels of armour plate along the sides. Imperial War Museum collection, IWM A9838

    The LCA was a small, mass-produced craft which took troops the final few miles from ship to shore and which was used in the invasions of Sicily, Normandy, south France, Walcheren and the Scheldt; as well as across the Far East. It was built largely from wood; a steam-bent keel of Canadian elm and mahogany frames covered in a shell of double diagonal teak planking over which some steel armour plating was bolted. This sort of construction suited small boat builders used to making wooden yachts, rowboats, fishing boats etc. but such businesses were already heavily engaged in war work. Coach-builders, who were skilled in assembly techniques and working with composite structures of steel and wood – and were more than familiar with the Ford V8 bus engines that powered the LCA – were under-employed during wartime and so were perfectly suited to taking up its production.

    Such was the importance of the LCA to the war effort that the Admiralty wouldn’t allow its designer – Thornycroft – to manage production directly. Instead it organised a huge network of subcontractors; bus and coach builders, furniture & cabinet makers, joiners… Anyone who could work wood on an industrial scale. Anecdotal evidence suggests businesses around Portobello were involved in producing teak body parts, which were taken to Marine Gardens for assembly onto the hull frames. The largely complete little vessels were launched into the Forth down the slipway and towed to a shipyard for final fitting out – west along the Forth coast to Granton or Bo’ness, east to Cockenzie or across the Firth to Burntisland and St. Monans. About 2,000 LCAs were built across hundreds of assembly yards and thousands of subcontractors and although I can’t find specific production volumes for Marine Gardens but by the time of Operation Overlord in June 1944, some 60 a month were being turned out.

    Once the local supply-chain was established and the workforce had been upskilled for the production of LCAs, larger craft were entrusted to Marine Gardens and a number of larger and more complex Landing Craft, Mechanised (LCM, predictably) were next built, with the first launched in November 1944 and series production entering the water in January 1945. The LCMs built at Marine Gardens were the Mark VII version, displacing 28 tons (63 tons fully loaded), 60 feet long by 16 feet wide and powered by two Packard diesel engines whose 290 horsepower could get a top speed of 11 knots. They could carry two light armoured vehicles or one larger one weighing up to 35 tons.

    29th January 1945, launch of an LCM at Marine Gardens into the Forth by the Lady Provost of Edinburgh, Diana Falconer, wearing the uniform of the Women’s Royal Naval Service (WRNS or Wrens) and being presented with a bouquet of flowers by one of the female welders, Mrs Duncan. This was the second such launch from the works.

    The vessel shown above is the LCM Mark VII, a late-war British-built variant of an American design by the Higgins Corporation that was suited to mass production by a relatively unskilled workforce. The Evening News reported multiple launches throughout the final year of the war; one more in February (launched by Lady and Sir William Young Darling, two in March launched by local women who worked on them, one in April and one in June launched by Mrs W. McDonald of Downfield Place, a worker who had won the SMT Saving’s Group competition. Up to twenty-nine of these craft may have been built at Portobello and after the war a scale model of LCM7174 was presented by SMT to the Scottish United Services Museum for display in Edinburgh Castle.

    LCM7174 at sea, this was the prototype vessel launched at Marine Gardens in November 1944. Imperial War Museum collection, A27908

    I haven’t yet found any further details about the work that took place at Marine Gardens during the war years – they may also have been assembling military trucks. However we can get a little more insight on Canmore Trove, which shows architects drawings for air raid shelters and emergency decontamination showers at the works (the latter being a very Heath Robinson arrangement of a bucket on a pulley with a bit of string and a pull handle!). The relative extent of the female versus male facilities gives an indication of the balance of the sexes in the wartime workforce.

    After the war, SMT retained the older half of the site based on the old Ballroom and operated it both as a coachbuilding works and later a general bus depot. The government-financed factory to the west was put up for disposal and in 1947 was allocated to Hayward Tyler Ltd. to build oil pumps and to Graham Enock Ltd. to manufacture milking, milk bottling and bottle washing machinery. SMT rebuilt their works around 1963, demolishing the remains of the old ballroom in the process, and were joined next door at this time by the rival Edinburgh Corporation Transport, who opened their Marine Garage on the site next door, which had been the football and speedway stadium.

    SMT became part of the state-owned Scottish Bus Group, with its organisation restructured into area bus operating companies, trading as Eastern Scottish in these parts. Eastern was reorganised in 1985 ahead of deregulation of the industry in 1986. Marine Works was placed into an engineering subsidiary called SBG Engineering Ltd. They did work for the various SBG companies as well as contracting, including body panel and spray painting work for British Rail’s nearby Craigentinny depot. When the privatisation of the Scottish Bus Group was planned in 1989, it was decided that SBG Engineering (which also had major works in Motherwell, Kilmarnock, Kirkcaldy and Inverness) was not included, and Motherwell and Marine Gardens were unceremoniously shut down.

    Remarkably, a substantial part of the wartime factory still survives (for now) as a car servicing works and salerooms. The building below is that which can be seen in the aerial photo at the head of the slipway.
