CP/M is a toy operating system and Windows is a child of CP/M. Windows can never escape it's legacy. The CP/M clone Quick and Dirty Operating system sucks and NT can never leave behind it's impact no matter the mountain of patchwork they may create.

Very Nice!!!!! 🤣😂

**use Jetson Nano, run some vision AI models and compare them on performance running on the same hardware in both image description and character generation 👍

** Would love to develop a facial recognition AI system for my security cameras. Woohoo, even signed by Jensen! 🙂 Thanks Dave!

** Would love to see reinforcement learning in action-an RC car following a line with computer vision and a robotic arm learning to move objects. Even better if they come together into an RC car that fetches sneakers and picks up dirty socks! Surely it's been done in labs, but how awesome it would be to know how to reproduce it and see with your own eyes how AI learning the ropes?

Show the code and let me compile it myself to becsire what I get. End of the discussion.

A point of clarity and a bug often repeated. "su" does NOT stand for "super-user" - it stands for "SWITCH user" - root just happens to be the default user if none was specified, which is why people think it stands for super-user. But su, and by extension, sudo, can switch to any user.

Nice show once again, I thoroughly enjoy listening in to Glenn and you , the ending with the chairs is quite nice and pleasent.

You are literally autistic by choice, let that sink in, you wear it as a badge because its not real to you at all.

everyones gotta be a victim even a millionaire, freaking man child

so gross, you are not autistic you fool

The servo-driven heads needed feedback to know where the head-stack was and so one side of a platter had concentric magnetic patterns that were written to it at the factory. Drives such as the Maxtor XT-1140 had “servo tracks” and a voice-coil to actuate the positions of the heads. Other late 1980’s hard drives, such as the Seagate ST-225 (10 MB capacity!!) used a stepper motor instead. Usually, when the driver chip for the stepper motor died it’d lose position as there was no feedback mechanism so data would get overwritten when it was erroneously on the wrong track. Replacing that driver usually fixed it but a new low level format was needed to wipe the drive so it could be used again. As well, if platters in a stepper drive needed replacing you could simply do the same. Not so on a servo drive as the servo-track platter could not be disrupted at all or it was almost always “game over”. I used to fix hard drives in the late 1980’s in Tukwilla and we’d visit Microsoft to open dead drives there at there campus so we could leave the platters with them removing any chance of stealing valuable data. MS would supposedly run a drill through the platters before disposing of them. In addition to any repairs needed, we’d install new platters in our Class-100 clean room. And if it was a Maxtor servo drive we’d write the proprietary servo-track back using the in-house “servo-writer” that I helped design and build. Sometimes a drive would not spin at all because the heads became so flat that they got stuck to the extremely flat platter. We called that “stiction” and it was usually not so fixable as a new head-stack probably cost similar to the hard drive itself. However, if one could free it up long enough to get the data off the drive there might be useful value in that. 5.25” IDE drives back then held only around 5 to 120 MegaBytes of data. The Seagate ST-225 was a $200 drive of 10 MB capacity that we could usually fix for a flat fee of $100. MS was ahead of its time for wanting to “recycle” but given that so many people of the great Northwest are grounded and sensible, it wasn’t a surprise. Those were great times and your video, Dave, rekindled those memories so “thanks”!

I took spanish first, latin was very easy after knowing both spanish and English

hi Dave and Glen, love the format and banter, I especially get a kick out of the PDP sagas, just way too cool. Keep it up. From the Land of the Morning Calm.

Never install a browser-extension that is not open-source.

** my idea for a Jetson project is to make a sign language translator that uses small vision transformer models. This would be a good use case as a small sign language translator for example government offices where it could be used to accomodate to those who are mute or deaf.

Grandpa Was RIIIIIIIIGHT

Very good video of your back and forth, really dig the old history of things. Thanks

? Can you reach down one step further because I have almost enough, but not quite enough knowledge to understand your wisdom about passwords. I am not sure if this qualifies as a curse of knowledge issue. It is probably of a lack of my knowledge issue. Or can you recommend a source of information and definitions that can catch me up to the point I can understand?

Until Glen mentioned Saskatchewan I thought he had a Minnesota accent.

Hahah had a seagate that wouldn’t spin and had one directory critical to machine ops. Remove disc cover , from separate box booted an 775 with win7 pro, open file manager , power to drive and lightly turned center hub… spun up, found directory copied to usb, and the Hkeys. Then tried to boot once more and it died. Built a new box reloaded system software and copied those files and Hkeys.. shazaaam. Customer next day. Not even a that boy, save my company’s butt cause the site tech never imaged any drives. And the customer got their work out on time , customer vp thanked me. I had three 2T external loaded with Pwd protected images, 10 boxes scsi waiting off line to plug and play that use Unix 5.

Had a hard drive (miniscribe) that got damaged by a lightning strike... which came in on the phone line on my BBS... The Modem was totally toasted, and an arc from the modem went to visit the miniscribe that was near by... A burn on the side of the miniscribe and a tiny hole in the sealed unit spelled DOOM for that 30 meg monster... (20 meg MFM turned into 30 with RLL..)-- I yanked the modem (a 2400 baud commercial board)--- and the computer came back to live, but C did not spin up. I ended up doing a "twist" of the chassis to get past the burned spot on the motor of the drive...and it spun up! Then did a big backup to a new 40 meg drive... sys'd that drive, and away we go.... NO bad spots seen at that point. But the drive was ready to go to the great dumpster in the sky... Had a friend who was working for Seagate in the warehouse at Tech Data. Would you want to hear a tale about moving manufacturing to the far east? The women doing the assembly work over there (Singapore?) could not get some of the high precision parts to go into the chassis of the drives. The local "management" who had no idea what materials science was said "Just use this WD40 on the chassis and motors, spindles and so on.... End result was it was not easy for the women to fit the parts into the chassis!!! Success. Sorta. Run the low level and then ship the drives back to the US. Well... When they arrived, it was all good.. For a week or so. However, while running, the drive got warm.. Warm enough to get the WD40 to become fluid... And ran to the spindle motor, then up the spindle...And from there, out across the platter. When the drives were powered down, you have a real good chance of the heads arriving on one of the WD40 trails on the platter. Next time you turned the drive on, nothing happened... Would not spin. People tried the drop thing.. no good.. they tried twisting the drive to get it to spin.. Nope.. Return it to Tech Data for a new one.. and another ... and another.. and another.. Seagate had palettes of them gathering at their distributors... That's where my friend got hired by them to do repairs in a new clean room at Tech Data. They sent spindles of platters for both 6 and 3 in drives for him to install, along with head assemblies. (Some of the drives had the heads so thoroughly glued to the platters that they ripped off the arms..) He replaced a bunch of platters every day, and collected them on the same spindles that the replacements came on. They made great frisbees to chop down shrubs and small trees. No good for computing of course. (when he opened his car's trunk, there were 2 spindles of 5" platters, and a spindle with the 3"...)--- and that was only a week or so worth of work at the mini clean room....

I bought a 80mb roll and it needed to be slapped against the case to get it to start.

Super.........boring!

** My idea is a AI program that catalogs and indexes a persons numerous pictures that they collect on their pc from phones, cameras, different devices. Have it learn content. "Jack and Jill on hill." "Jack falling down hill" to make it easier to determine where photos were taken and when.

Once I asked for ChatGPT to create a prompt to use in another chat and it included the word please. I asked why and it said that being polite was helpful in getting a better response. 🤔

I wouldn't fire them because they didn't know ipsec, I'd fire them for refusing to figure it out

I remember seeing Bill Gates’ smart home controllers and devices featured in an issue of Popular Science in 1998 when I was in 6th grade.

Well, might have local beers due to different water composition, minerals and what not that affects taste, so you might have to take that into account…

*** I worked at Bell Labs in the early 90’s. My day job was everything from PDP’s running Unix V10 to SGI Irix etc. Oh yeah. And an XMP.

11:51 Binance sucks!!! They won't even let you do USD withdrawals

Omg I just got a thumbnail with the engineer from The Matrix on the side when I clicked your video, and DAAAAMN it struck me how similar you guys look 😅

25:37 - "Smoker's Teeth Yellow" - I never smoked, but I've been in those shops... the Good Old Days...

20:54 - My favorite beer in Canada is Sleeman Ale (Guelph, Ontario) - mostly because my father-in-law put in a supply before we visited...

17:59 - Just reminded that we had a UNIX Internals course using the "Kernel Structure and Flow" (1988) by Reiken and Webb taught by Bill Reiken. He had some his homework before teaching the class as Harris. He asked "why is there no 'elevator algorithm' in your disk driver"? "Because the elevator is in the hardware, including process priority..." - y'see, we built real-time machines, and were working on a real-time UNIX...

17:30 - Oh, yeah, with the HCX-7/HCX-9, you built the kernel using Make. And when something went wrong, it went very, very wrong...

15:00 - RSX-11 - Really Sick eXecutive, Eleven Days to compile anything...

Thanks guys.

That's it! I'm switching to Linux

** SLAM : simultaneous localization and mapping

Worked in a computer shop in the 90's, had a lady from a Korean church bring in a dead computer that she was desperate to get working. Hard drive wouldn't spin. Ended up actually taking the top off the drive and gave the platter hub a spin and it spin up! 100% recovery of all the data. Might have been a DEC Rainbow. Hard to remember that far back...

Wow, in my real life job compiling code for an onboard aircraft computer with 32kbytes of memory was done overnight. It actually only took about 2-3 hours, but we didn’t want to wait, either. Note: circa 1979.

Regarding stiction. At work at the time we had a i386 for misc tests, Linux being one. This one had a disk that had stiction problems. It was an old disk so the spindle motor was accessible between the enclosure and the control board. So to resolve the issue a hole was drilled in the chassis so you could put in a small screwdriver and nudge the motor in case the disk would not start. Think we had it like that for a year or so until we got a bigger disk.

Two systems sharing one drive is possible, but they need to have an extra connection between the systems to coordinate who is currently in control while the other waits or shoves the data to be written oder the extra connection to the other system to write the data. I THINK, not know, the SCSI bus, if shared between two system, can be used to coordinate who is using the drive. But I am not sure whether I actually read it or whether I just think I read it somewhere.

Suspect dust, debris or oxidation in your bad card slot. We used to “clean” the card contacts with a #2 pencil eraser.

The Mac SE/30 HDDs were notorious for sticking. A good slap on the right side and you back in business.

I had a hard drive fail once, and it was very likely a spin problem, and so I read up on how I could run it just long enough to rescue the data from it, and found out to freeze it, as the shrinkage will free upp the platter and allow it to move at the proper speed before it gets too hot too again, and so I did, and sure enough it worked! I got all the data off, and thought I'd play with it some more and wrote and read randomly from it for a few hours and it got all messed up again, but worked for a few hours, so I got lucky. So there's one of a few possibilities that may still work with a modern hard disk drive, if needed.

1:59 When I was in college, we submitted our programs on punched cards to the operator. The operator would put the job in the queue. You'd go to a class or back to the dorm. Later, you'd go back to the computer center and see if your job was done. Your card stack and printout would be in a mail slot. The computer was a CDC 3300 with a custom OS. If you submitted jobs at 1:00 or 2:00 AM, they might be completed in as little as ten to fifteen minutes. That was often when I went to debug a difficult program. You didn't even try to get anything done while the university class scheduling job was run. It took a day or two to complete. When you scheduled classes, you were given a randomly determined time based upon the first letter of your last name. You went to the basketball coliseum at your assigned time and picked up punched cards at tables for the classes that you wanted. There were people tasked with making sure you only took one card. If the class was full, no card for you. That's the reason for the random time. I think seniors near graduation had priority. When you were done, you submitted your card deck to be processed later. I don't remember how you got your schedule. I think you went to your school office and picked up your printout. I seem to remember that there was a "first choice" "second choice" for some classes. The order of the cards was important.
