The Chinese raised warfare to an art, via Sun Tzu. The Japanese raised individual (Samurai) combat to a high art via Miyazaki Musashi.
Two great books that go together Sun Tzu's 'The Art of War', and Miyazaki Musashi's 'A Book of Five Rings' both are fascinating works that can profoundly change ones outlook on life when studied.
The Cray XMP-48 had up to 1 GB of RAM. That RAM subsystem was bigger than the CPU core. Apple had one back in the early 90's 250K watts 230 tons including its cooling system. IT was fed data and storage from a herd of VAX 11/780s with wash-tub sized HD units. The residential neighbors to that building had lots of complaints about lights dimming when that machine started burning midnight oil.
My mentor and I built a RC model car that on smooth concrete could do 105MPH, and sustain it for 8 - 10 minutes. It had so much torque that 'punching it' off the line turned it into a 'ground-bloom-flower'. Factor in the car's scale MPH (1/12 scale) and it was doing 1260 (scale) MPH.
I used to impress my nerd-friends by 'drag-racing' cars going down the street (at 25 - 30 MPH) and passing them before they had gone 100 meters. That is the car being raced was going 25 MPH and the RC car was going from zero to whatever was needed to overtake the fullsize car before it got through to the end of the block. That wasn't even using the most advanced motor drivers available back then, Back then PWM DC motor drivers were terrible for reliability and performance because FETs were too small and power transistors had more losses than a simple high wattage rheostat driver.
That was with NiCad batteries, resistor-based DC control, and traditional DC motor tech back in the late 70's. If I were to build that RC car now.... it would easily do 205 (real) MPH due to improvements in battery tech, and motor tech in the last 35 years. The only thing impressive about this car is that it is a full-sized Le Mans compliant vehicle.
Issac Newton was full-on silver-grey before he was out of his twenties, the man didn't need a powdered wig to look 'distinguished'! I was salt&pepper before I was 30. One of the young turks at a startup I signed on with (long gone now) seemed to think I was older than I was at the time and, asked me indiscreetly during a Friday Happy hour if I was going through mid-life crisis because I drove a two-seat sports car. (a decrepit RX-7 [G1], never having been married, I had no use for a 'utility vehicle') I laughed him off and pointed out that if it was mid-life crisis, I had picked a really crappy penis extension(aka sports car). He was old enough to be embarrassed, but not experienced enough to understand why.
The day the startup folded... almost a year later (IT market got cold feet after 9/11) the young guys made a point of individually, dropping by my cube as I, and 95% of the staff packed up our personal effects and lined up for exit interviews. They wanted to know if I was angry or disappointed, or even sad that the business had failed. By the time the last of them had dropped by... I was in tears. Not because I was upset about the business failure, but because I was gonna miss these kids. They all had degrees from big-name schools and had their whole careers ahead of them... for me this was just another gig that didn't make it out of the incubator. I think one of the reasons they afforded me that little show of respect of dropping by to say fare-well is because I had shown that, even as a 'grey-beard' I still loved what I was doing, and helping create awesome software, and hardware is a journey not a reward. It also helped that many of them had cut their teeth on the Apple//gs and I had been one of the lead test engineers on the system ROMs. One of the spare labs in the office had been set up to accommodate our various//gs systems.... and we'd basically built an Apple lab complete with one of my old Macintosh IIfx boxes acting as a file share/internet router, running AUX.... one of those little geek exercises that helps cement team bonds. Fun times.
That xkcd cartoon gets plastered into just about every discussion that has ever been initiated on/. since the cartoon was first published. It has relevance, but it is, at this time bordering on redundant, since every credible geek on/. knows this aspect of crypto, balls to bones.
Maybe you should take your.sig to heart, rather than wearing it like some geek-cred-badge. Also note that the tool that once again taped this classic cartoon to the thread did NOT get a risk free karma boost... why? Because the link is not helpful, funny or even relevant to a discussion about OCR resistant font faces.
Using a CRT to scan data onto high persistence phosphor, and then use optical sensors to feed that data back to the electron gun created the first dynamic storage system. This machine not only was the first machine with electronic storage, but was the first machine to exercise an example of Dynamic Random Access Memory.
>Unfortunately, one of the clock phases was missing on the expansion connector.
That is because the missing clock phase(ø2) was redundant on the Apple ][. Phase 0(ø0 -- also the clock input of the 650x processors), as it appears on the I/O bus, was already delayed to be in the same relative phase angle as ø2 output of the 6502. When ø2 && ø0 are low the processor bus is not in use. In the Apple ][ this was used to stuff a video/DRAM read cycle on to the memory bus while the next address cycle was still in transition. One could argue that ø2 would be more accurate, however WOZ's insight was realizing that ø0 and ø1 were more than adequate to keep the I/O timing within spec.

Problem is the FAA has a certification process for GA engines that takes most of a decade to get equipment certified. Good luck getting a modern ECU and engine certified before your startup runs out of money.
The whole point of lead in avgas is to reduce the burn rate of the fuel. This prevents knocking at high compression ratios where low-octane gas will detonate before the cylinder passes TDC. The reasons this detonation occurs has to do with the temp increases caused by the compression stroke. High octane(or TEL) fuels have a higher flash-point than low octane fuels. One additional cause of detonation is hot-spots in the cylinder, often caused by sharp edges, or points on the machined parts, and/or carbon, burned oil, coolant deposits. Any of these conditions can cause knocks. These knocks will destroy an engine in short order, which is why lean-burn engines have knock sensors. The sensor signal tells the ECU to richen the mixture a bit when detonation is detected. Over all the conditions which will cause detonation are not always predictable, temp, load, atmospheric conditions, etc. all influence when detonation will occur.
This would all be moot if we used direct injection in gas engines(which is what diesel engines do) at higher compression ratios. However there is a tradeoff; higher compression ratios in gas engines create more NOx compounds, and these have been shown to cause a lot of environmental damage.
It doesn't matter who caused the accident. If during the investigation a person is found to be intoxicated, there would be a pause to arrest the DUI suspect; return to investigation. Now it may be that the DUI suspect DID NOT cause the accident. (Rear-ending of the DUI suspect for example*). I would expect an HONEST investigator to note that in their report, rather than pinning the accident on the DUI suspect.
In all the West Coast States, rear-ennding another vehicle is an automatic fault. It means you were following too close/ not paying attention. There only a few exemptions to that, and they are fairly obvious to a trained accident investigator.
I do not even know where to begin. Most of the nonsense involves not understanding how Mac Video/Audio workstations are used.
Some have correctly pointed out that external RAID0 is the only sane way to deal with TB scale video and and audio projects. However the one that really gets me is the use of RAM and SSD on these configurations: The SSD is for the OS and MAYBE the apps. The new PowerMac supports up to 128GB of RAM. The SSD is NOT being used as a swap device. Like any other *NIX based system you can assign the backing store to ANY block device. On MacOS if you ever start seeing page swaps to disk, YOU ARE DOING IT WRONG. Add more RAM. Mavericks also supports heap compression, so instead of paging to a block device it compresses LRU'd heap objects to avoid knocking them out of ram. Even so, if you are thrashing the paging system on a Mac YOU ARE DOING IT WRONG.
As for ThunderBolt 2, it offers a PCIe link to arbitrary external devices. Who gives a rats ass if it cant support 16x PCIe 4. In most cases that might be interesting, the link speed is not as critical as being able to stream ~16GB/sec to another box that could have additional CPUs and GPUs. ThunderBolt links are transparent to PCIe. The idea is that there WILL be VERY expensive processing systems built that use the local link capability of ThunderBolt to allow a MacPro to do coordinate insane levels of parallel processing.
You people are still thinking INSIDE of the PC chassis. Think outside the beige box. PCIe to an external rack of CPU/GPU nodes seems like a really good idea for putting a crapload of processing power next to your desk.
A friend of mine from many moons back told be of taking over a VMS cluster. From what he told me all he had to do is keep spawning processes until the CPUs fell over from lack of resources. Now, he did not intend to drop the cluster. He did however intend that his process batch take over the entire cluster. He was nearly kicked out of uni for this hack. It was only by showing that he did not intend to 'harm' the cluster that he avoided summary dismissal. He was never allowed to submit jobs to any cluster on the campus.... he was forced to become a UNIX expert.
Did a stint as the DoO at a call center. We recorded every call that was initiated or terminated at the site. The daily backup was only a few 100MB, a half-GB at most.
Some years ago I stumbled across a list of corporations that owned (as in owns the land rights, not the facility that runs the site) landfills. 3M (Minnesota Mining and Manufacturing) had the largest holdings and the top 80% of the list were all mining corporations.
so yeah, when raw resources are all too expensive to mine, the mining corps will just move their extraction operations to landfills.
When first researched the project it became clear that using steel wire like that creates some rather heinous mechanical constraints. The electronics are bonehead simple... The mechanical stuff needed to safely transport the wire and bale it properly onto a reel is fiendishly difficult to get right. Failing to get it just right makes any further attempt to read the wire impossible due to tangling. Anyone who has had to de-tangle a fishing reel knows what I mean. Now to add more difficulty, the line is brittle and a little thinner than human hair.
Or, ya know, externalize the surplus... Start some wars.
Look at the current gender demographics of Russia for an example of what happens to the ratios after 50+ years of conscription into un-winable, and under supported military conflicts.
Sucks to be the rest of the world if China pursues such an approach. They can throw an insane amount of 'man-power' at just about anything now... I'm sure that makes their neighbors kind of nervous.
Kinda funny. some time ago I met a codger that wanted to speel-in some old wire recordings...
It was impossible. Too much cost for too little.... he had no idea if any of the reels were blank...
We could not even determine for sure what mechanical format the reels were. Who made them? (they are unmarked) What system(s) they were compatible with no clear coding on the spools? (Mechanical dimensions are not searchable... and are ambiguous for that tech)
It was a wash. I'm sure those reels are quite readable, but short of engineering a custom machine... they are effectively unreadable.
Having worked in software development for 30 years, let me tell you a dark little secret.
QA programs are never enough.
Dropping previous moderation to comment here:
Having worked in SQA for over 17 years I can tell you PM NEVER listens to SQA unless the app would be DOA on more than 20% of the target customer's machines. On occasion a XXO would override PM and tell them no... you cannot RTM until you fix *THIS* issue... but security, data loss, customer satisfaction were never significant guidance to PM or XXO decisions.
And these issues are not deep... this is low hanging fruit, more often than not. PMs and DEVs hate SQA and wish we would DIAF. They see us as a headache to be mitigated, not an instrument to measure quality.
