Unix introduced /
as the directory separator sometime around 1970. I don't know why exactly this character was chosen; the ancestor system Multics used >
, but the designers of Unix had already used >
together with <
for redirection in the shell (see Why is the root directory denoted by a /
sign?).
MS-DOS 2.0 introduced \
as the directory separator in the early 1980s. The reason /
was not used is that MS-DOS 1.0 (which did not support directories at all) was already using /
to introduce command-line options. It probably took this usage of /
from VMS (which had a more complicated syntax for directories). You can read a more detailed explanation of why that choice was made on Larry Osterman's blog. MS-DOS even briefly had an option to change the option character to -
and the directory separator to /
, but it didn't stick.
/
it is recognized by most programmer-level APIs (in all versions of DOS and Windows). So you can often, but not always get away with using /
as a directory separator under Windows. A notable exception is that you can't use /
as a separator after the \\?
prefix which (even in Windows 7) is the only way to specify a path using Unicode or containing more than 260 characters.
Some user interface elements support /
as a directory separator under Windows, but not all. Some programs just pass filenames through to the underlying API, so they support /
and \
indifferently. In the command interpreter (in command.com or cmd), you can use /
in many cases, but not always; this is partly dependent on the version of Windows (for example, cd /windows
works in XP and 7 but did not in Windows 9x). The Explorer path entry box accepts /
(at least from XP up; probably because it also accepts URLs). On the other hand, the standard file open dialog rejects slashes. //
The underlying Windows API can accept either the backslash or slash to separate directory and file components of a path, but the Microsoft convention is to use a backslash, and APIs that return paths put backslash in.
MS-DOS and derived systems use backslash \
for path separator and slash /
for command parameters. Unix and a number of other systems used slash /
for paths and backslash \
for escaping special characters. And to this day this discrepancy causes countless woes to people working on cross-compilers, cross-platform tools, things that have to take network paths or URLs as well as file paths, and other stuff that you'd never imagine to suffer from this.
Why? What are the origins of this difference? Who's to blame and what's their excuse?
Why does Windows use backslashes for paths and Unix forward slashes?
– phuclv Commented Aug 13, 2018 at 16:55While your question is perfectly reasonable, your phrasing seems to imply that you think the UNIX approach was already a de facto standard and MS-DOS was unique in deviating from it. See, as a counter-example, how the Macintosh OS used
:
as its path separator until MacOS X introduced POSIX APIs. This question goes into the history of that decision and answers point to:
and.
as path separators predating UNIX's use of/
.
– ssokolow Commented Aug 1, 2022 at 20:10@ssokolow UNIX was there with its forward slashes long before MacOS and DOS were created.
– SF. CommentedAug 2, 2022 at 8:13@SF. And, as the answer phuclv linked says, DOS got it from CP/M, which got it from VMS. I don't know why VMS chose
\
when UNIX chose/
seven years before VMS's first release (going by Wikipedia dates), but it wasn't a settled thing. Other designs were using:
and.
in the mid-60s, half a decade before UNIX decided on/
, and UNIX broke from Multics's>
because they wanted to use it for shell piping.
– ssokolow Commented Aug 3, 2022 at 5:31Use of UNIX back then wasn't nearly as ubiquitous as it is today. Almost all of industry and many schools used manufacturer-written and -supplied operating systems, especially from DEC. And within the more well-known CS schools (not that it was called "CS" then) there was also a lot of use of homegrown OSes. So the influence of UNIX wasn't as pronounced as it is today, as well - that took many years to develop.
– davidbak Commented Aug 3, 2022 at 16:51
A:
PC/MS-DOS 1 used the slash (/) as the command line switch indicator (like DEC's RSX11 and DG's RTOS before), so when DOS 2.0 introduced subdirectories, they did need a new one. Backslash () came somewhat natural - at least on US keyboards.
With 2.0 IBM/Microsoft also tried to reverse that decision and introduce a syscall (INT 21h function 3700h and 3701h) and a CONFIG.SYS option (SWITCHAR=) to set a different switch indicator. All manufacturer supplied commands would obey that new char. Set to a hyphen (-) would make the syntax more like Unix.
In fact, in paths, the OS didn't care. All dedicated path names, like in syscalls, can be written with either slash. It's only within the command line scan of each command, that simple slashes get interpreted as switch indicators. The idea was that people could/should migrate to a Unix-like style, but that didn't catch on.
With DOS 3.0 the SWITCHAR= option got removed fom CONFIG.SYS, but the syscalls are still availabe up to today. //
A:
The README.txt file in the MS-DOS 2.0 source code, which was apparently intended to guide OEMs on how to build custom DOS builds for their hardware, indicates that the decision to use backslash was requested by IBM: Microsoft had been originally intending to use forward slash, and the change happened late in the development process. This is probably why the kernel ended up supporting the use of either character -- it was, presumably, too late to change over fully.
The user manual contains some significant errors. Most of these are due to last minute changes to achieve a greater degree of compatibility with IBM's implementation of MS-DOS (PC DOS). This includes the use of "\" instead of "/" as the path separator, and "/" instead of "-" as the switch character.
This is true, but very widely misinterpreted – the forward slash as an option character did not come from IBM, IBM's own operating systems (mainframe and minicomputer) never used that syntax. What IBM objected to, was Microsoft's proposal in DOS 2.0 to change it from slash to dash – IBM cared about backward compatibility. But IBM wouldn't have had a problem if Microsoft had made it dash all along, starting with DOS 1.0; IBM didn't care what the syntax was in the initial version, but they didn't want it changed in a subsequent.

In 1945, six women pulled off a computing miracle.
They programmed the world’s first computer—with no manuals, no training.
Then, a SINGLE assumption erased them from tech history for decades.
The story of how ONE photo nearly deleted computing’s female founders: 🧵
Kathy Kleiman, a young programmer, found old photos of women standing beside ENIAC—the first general-purpose computer.
When she asked who they were, curators said: “Probably just models”...
But Kleiman had a feeling they were something more:
Program ENIAC—a machine the world had never seen.
It was 8 feet tall, 80 feet long, and weighed over 60,000 pounds.
The engineers built the hardware...
But someone had to figure out how to make it do anything:
They were the world’s first programmers.
First, they were hired as “human computers” to calculate missile trajectories during WWII.
Then chosen for a top-secret project unlike anything before:
Security restrictions kept them out of the ENIAC lab.
They had to write programs using only blueprints and logic diagrams.
No manuals. No programming languages...
So how do you code something no one’s ever coded before?
By inventing the process from scratch.
They built algorithms, flowcharts, and step-by-step routines—on paper.
Then, once granted access, they programmed ENIAC by physically rewiring it...
And that’s where things got even harder:
There was no keyboard.
Programming meant plugging thousands of cables into the right configuration—by hand.
It was almost impossible to program.
But they pulled it off anyway:
On this day in 1975, Bill Gates and Paul Allen founded a company called Micro-Soft in Albuquerque, New Mexico.
then write up the marketing letter, format it and let it all rip on a Diablo 630 daisy wheel printer. Many, was that thing loud. Made the whole office grimace when I kicked it off. //
Re: Loud printers
You've obviously never used an ICL 1900 lineprinter: these could print at 160 characters per line at up to 1300 lines per minute. The mechanism was based round a hollow drum the full width of the paper with 160 rings of characters, each containing the complete character set. These were organised so that each embossed row had the same character in every position. The embossed drum was installed behind a row of 160 hammers and a inky ribbon the full width of the paper: both paper and ribbon scrolled vertically, though not at the same speed. The print hammers were driven off a very latge capacitor in the printer's body.
The printer was loud enough when printing invoices, etc, but George 3's print driver could easily outdo it. It separated documents by outputting, IIRC, a page throw, a job title, 10 full width lines of 160 asterisks and another page throw: when this happened the printer almost jumped off the floor and made a noise similar to a short burst from a machine gun.
These ICL printers were much louder than any IBM lineprinter I've ever heard running. That's because IBM used train printers: the character set formed a rotating chain running across the paper path and were designed so that only one character could hit the paper at a time. //
Re: Loud printers
Impact printers were getting fairly close to their practical limits in terms of printing speed. There was a flurry of development in the early 1970s to come up with better solutions. Xerox produced something that was kind of a hybrid between a drum printer and a photocopier - a set of flash lamps illuminated the correct characters on a drum transferring their images optically to the selenium copier drum. That got printing up to around 4000 lines a minute. Honeywell introduced an electrostatic system using a dielectric paper that raised speeds to 18,000 lines per minute.
However, it was IBM that developed the first laser printer - the IBM 3800. Its initial version managed only a shade under 14,000 lines per minute, but a later version raised the speed to over 20,000 lines per minute - around 2.8 km/h. With paper running that fast , a laser and a hot fuser unit, suddenly noise was not the only hazard. There's a fascinating training video for operators that shows the massive scale of the beast.

According to a report by TechSpot, Western Digital will now focus solely on its native hard disk technology, with the SSD division being spun off into SanDisk. This means that lineups like WD_BLACK will now be manufactured by SanDisk instead of WD themselves, and this will ultimately mean that Western Digital branding won't be there anymore. //

Goeckeler decided to spun the company but resign and become Sandisk CEO, Irving Tan is just a guy appointed to keep at it. Goeckeler is one of the most disliked CEOs in the industry (voted the worst actually), and is chasing his quarterly growth and profits as always because that means prize money for him. He tries to do this every year, inflate the growth to maximize how much money he gets and bet the company in the process.

Here are a few ways to securely erase your hard drive:
DBAN (Darik's Boot and Nuke) – Use this free tool that overwrites data multiple times, making recovery impossible.
Windows Secure Erase (for SSDs) – If you're wiping an SSD, use the manufacturer's secure erase tool (e.g., Samsung Magician, Crucial Storage Executive).
Command Prompt (for HDDs) – Run cipher /w:C: to overwrite deleted files on the selected drive.
The HP-41C overcame these limitations by adding alphanumeric capabilities to both the display and keyboard. The keyboard had an "Alpha" key that toggled the keyboard between alpha and the normal calculator mode. (The alpha characters were printed on the slanted faces of the keys.) If the user needed a function not printed on a key, the name of the function could be typed in and executed. (About half of the HP-41Cs functions were preassigned to keys.)
Because typing out the name of a function could be cumbersome, the HP-41C added another toggle key called "user". The user could assign any built-in function or user program to any key. Once the keyboard was placed in user mode, any assignments made by the user overrode the label on the key. (With the gold shift key, this allowed two user functions per key.) The user toggle state remained set even when the calculator was turned off allowing true keyboard customization.
To make it easy to remember keyboard assignments, HP provided keyboard overlays along with preprinted labels for all built-in functions and blank labels for user functions. In addition, whenever a key was held down, its function name was displayed. If it was the wrong key, the user could continue to hold it until the display showed "NULL" when meant the function was canceled.
Of course, HP didn't just improve the human interface. The HP-41C had more memory (now non-volatile) than its predecessor, more functions, improved programming, and could be expanded with both RAM and ROM modules.
Ttcalc is a public domain programmable calculator for Microsoft Windows written by Stefan Seiwerth that is modeled after the HP-41C series of calculators. Download the program, unzip and see the readme.txt file for installation instructions. Run ttcalce.exe for the English version or ttcalc.exe for the German version. (The help file for either version is in German.)
I have a soft spot for fictional computers, having implemented compilers, bytecode interpreters, and even program synthesis for various made-up computer architectures.
This post is yet another dive into VM implementation, looking at a particularly fascinating ecosystem from Hundred Rabbits:
The Uxn CPU is a simple, 256-instruction stack machine
Varavara defines a set of peripherals that turn that CPU into an actual computer (display, keyboard, mouse, etc)
Unlike many fictional computers, the Uxn + Varvara ecosystem is sophisticated enough for actual use, and there are dozens of different ROMs – everything from text editors to drawing programs to synthesizers.
The Hundred Rabbits devlog motivates this design with far more eloquence than I could offer; I'd encourage you to browse their sprawling wiki of documentation, blog posts, and development notes.
My implementation is called Raven.
Uxn is the virtual machine powering the Hundred Rabbits software.
This one-page computer, programmable in Uxntal, is an portability layer with a focus on hosting graphical tools and games. It lives at the heart of the Varvara ecosystem.

Over the millennia, we have created security systems to deal with the sorts of mistakes humans commonly make. //
But it’s not the frequency or severity of AI systems’ mistakes that differentiates them from human mistakes. It’s their weirdness. AI systems do not make mistakes in the same ways that humans do.
Much of the friction—and risk—associated with our use of AI arise from that difference. We need to invent new security systems that adapt to these differences and prevent harm from AI mistakes. //
AI errors come at seemingly random times, without any clustering around particular topics. LLM mistakes tend to be more evenly distributed through the knowledge space. A model might be equally likely to make a mistake on a calculus question as it is to propose that cabbages eat goats.
And AI mistakes aren’t accompanied by ignorance. A LLM will be just as confident when saying something completely wrong—and obviously so, to a human—as it will be when saying something true. The seemingly random inconsistency of LLMs makes it hard to trust their reasoning in complex, multi-step problems. If you want to use an AI model to help with a business problem, it’s not enough to see that it understands what factors make a product profitable; you need to be sure it won’t forget what money is. //

“Technologies like large language models (LLMs) can perform many cognitive tasks”
No, they can’t perform ANY cognitive tasks. They do not cogitate. They do not think and are not capable of reasoning. They are nothing more than word-prediction engines. (This is not the same as saying they are useless.)
You should know better than that, Bruce.
RealFakeNews • January 21, 2025 12:35 PM
Part of the problem is AI can’t fundamentally differentiate a fact from something it just made up. It can check cabbages and goats are related via some probability, but it can’t check that a cabbage doesn’t eat goats because it can’t use the lack of data to verify if that is correct.
440-pound 1980s behemoth rescued from an Osaka restaurant days before demolition. //
For those who want the absolute largest CRT experience possible, Sony's KX-45ED1 model (aka PVM-4300) has become the stuff of legends. The massive 45-inch CRT was sold in the late '80s for a whopping $40,000 (over $100,000 in today's dollars), according to contemporary reports.
That price means it wasn't exactly a mass-market product, and the limited supply has made it something of a white whale for CRT enthusiasts to this day. While a few pictures have emerged of the PVM-4300 in the wild and in marketing materials, no collector has stepped forward with detailed footage of a working unit. //
Enter Shank Mods, a retro gaming enthusiast and renowned maker of portable versions of non-portable consoles. In a fascinating 35-minute video posted this weekend, he details his years-long effort to find and secure a PVM-4300 from a soon-to-be-demolished restaurant in Japan and preserve it for years to come. //
The full video includes lots of footage and details of the shipping and unboxing process, and confirmation that the TV still works after its incredible journey. Shank Mods also includes a breakdown of the internal design and processing hardware that went into such a uniquely large CRT and an extended discussion of the intricate process of calibrating and tuning the tube to deliver a sharp, color-corrected picture after years of magnetic and electron beam drift.
In the high-stakes world of semiconductor manufacturing, Europe has unveiled a groundbreaking achievement that rivals the cost and complexity of an Airbus A350. This state-of-the-art machine, meticulously assembled by a team of 250 engineers over six months, stands as a testament to European innovation in microtechnology. With ambitions to capture a significant share of the Chinese market, this marvel could reshape the global semiconductor landscape.
Since its inception in 1984, ASML has been at the forefront of semiconductor lithography. The company’s latest creation leverages Extreme Ultraviolet (EUV) technology, a bold move that has paid off handsomely. EUV lithography allows for the precise etching of intricate chip patterns, essential for the next generation of artificial intelligence and high-performance computing. According to industry leaders at the International Semiconductor Association, ASML’s commitment to EUV has not only doubled its revenue in the past five years but also set new standards in chip manufacturing.
The new ASML system promises to revolutionize microprocessor fabrication by reducing transistor sizes to an astonishing 1 nanometer.

Re: It just costs money
It's not the GHz clock cycle that is the problem. It's the smaller feature size of the transistors that increases the single event upset (SEU) rate. Yes, the two are inter-related, but one could conceivably build multi-core, chip symmetric multiprocessors based on the PDP-11 at today's feature sizes and not have GHz clock cycle times (and still end up with significant SEU rates.)

RSX11M - Dave Cutler
Anyone who read the RSX11M sources (driver writers especially) realised that Dave Cutler was a very very good programmer long before he worked on VMS and later Windows NT. He managed to get a multiuser protected general purpose operating system to work with a minimum memory footprint of under 32kbytes on machines with about the same CPU power as the chip on a credit card. (A 96kByte PDP 11/40 (1/3 mip) with 2 RK05 disks (2.4Mbyte each) could support 2 concurrent programmers - a PDP 11/70 (1 mip) with 1Mbyte and 2 RM03 disk packs (65Mbyte each) could support 10 or more.) During the many years that the CEGB used PDP-11 computers with RSX11M, I did not hear of a single OS failure that was not caused by a hardware fault - I wish that current systems were as good. //

Re: PDP 11 odds and ends.
Most real-time systems stayed as PDP-11 when the industry realised that the interupt latency on VAX/VMS was too slow for a lot of applications. You could improve it with a ccustomised VMS kernel but, in most cases, it was cheaper to stick with the devil you knew. Similarly, a friend worked for a measuring company that were using embedded PDP-8 systems as controllers well into the end of the 90s. used to drive round with a clip-on PDP-8 front panel in the boot of his car.

Re: PDP 11 odds and ends.
Its a certainly a CANDU reactor and its fuel bundle loader robots from what it looks like.
CANDU is a different type of reactor than what gets built most of the time, they can burn just about anything, from some unenriched uranium with some slightly enriched uranium at the same time, to thorium, to Mixed Oxide fuels partially from decommissioned nuclear weapons, to "fun" transuranic actinides and also (as a proliferation concern) some quite nasty fuel mixes which can breed massive (relatively speaking of course) amounts of Plutonium if the reactor isn't properly safeguarded. Thats where India and probably Pakistan bred most of their Special Materials.
And what's cool about this is if the PDP-11 is what GE is using in Canada for their loaders, then its probably what they're using in India, South Korea, Romania, Argentina and China as well, as they also have CANDU reactors or designs derived from CANDU. //
HAMR works on the principle that, when heated, a disk's magnetic materials can hold more data in smaller spaces, such that you can fit more overall data on the drive. It's not just putting a tiny hot plate inside an HDD chassis; as Seagate explains in its technical paper, "the entire process—heating, writing, and cooling—takes less than 1 nanosecond." Getting from a physics concept to an actual drive involved adding a laser diode to the drive head, optical steering, firmware alterations, and "a million other little things that engineers spent countless hours developing." Seagate has a lot more about Mozaic 3+ on its site. //
There is no price yet, nor promise of delivery, but you can do some wishful thinking on the product page for the Exos M, where 30 and 32TB capacities are offered. That's 3TB per platter, and up to three times the efficiency per terabyte compared to "typical drives," according to Seagate. Seagate has previously boasted that its Mozaic 3+ HAMR drives, under "aggressive field use stress tests," have seen more than seven years of head life.
Western Digital has its own 32TB drive, based on energy-assisted perpendicular magnetic recording, or e-PMR. Both companies have suggested their high-capacity drives are ideal for AI model training, given the gargantuan storage demands and energy pull of that job. Toshiba intends to move into the HAMR drive space, which accounts for all three of the major HDD makers' plans.

That reminds me of "The Plan"
The Plan
In the beginning, there was a plan,
And then came the assumptions,
And the assumptions were without form,
And the plan without substance,
And the darkness was upon the face of the workers,
And they spoke among themselves saying,
"It is a crock of shit and it stinks."
And the workers went unto their Supervisors and said,
"It is a pile of dung, and we cannot live with the smell."
And the Supervisors went unto their Managers saying,
"It is a container of excrement, and it is very strong,
Such that none may abide by it."
And the Managers went unto their Directors saying,
"It is a vessel of fertilizer, and none may abide by its strength."
And the Directors spoke among themselves saying to one another,
"It contains that which aids plants growth, and it is very strong."
And the Directors went to the Vice Presidents saying unto them,
"It promotes growth, and it is very powerful."
And the Vice Presidents went to the President, saying unto him,
"This new plan will actively promote the growth and vigour
Of the company With very powerful effects."
And the President looked upon the Plan
And saw that it was good,
And the Plan became Policy.
And this, my friend, is how shit happens. //
