I am trying to download a web page with telnet. I used to do this back in around 1998, and it worked.
I tried this at the command line on Windows 11:
telnet www.example.com 80
Then I typed "GET /" and hit enter twice. However, it returns a 404 instead of the web site.
Anyone know what's wrong?
Thanks.

The forum where you asked.

Help me to understand what I'm saying, and I'll explain it better to you
Rating helpful answers is nice, but saying thanks can be even nicer.

You're using the wrong tool. Try GNU Wget 1.21.4 for Windows instead
e.g. wget --output-file=example.com www.example.com
assuming, of course that you're not prevented from adding software to your system
You might also try curl shipped by Microsoft, but that processes the HTML. There might be a flag to give you the raw text, but I didn't see one in a brief perusal of the man page.
Bonus: both handle HTTPS negotiations, so that might make up your mind, right there.

Loved watching the his shows. ![Rose | [Rose]](https://www.codeproject.com/script/Forums/Images/rose.gif)
Quote: Mr. Lear’s entertainment career spanned the late 1940s to the 21st century, and he also found prominence in later life as a liberal political activist. But his legend was sealed in the 1970s, when he created a handful of shows that transformed the television medium into a fractious national town meeting and showcased the American family in all its hopes and dysfunctions.

He was a genius, for sure, even though he was a Liberal twit. I happen to have on my shelf every episode of All in the Family, and I'm planning a binge watch next year!

Seems to be common in the industry.
Yeah all in the family and Sanford were two of my favorites.

Agreed, I'd add Good Times and The Jeffersons to that list.

I finally read and completed the book, The Code Book: The Secrets Behind Codebreaking[^].
It was published back in 2002 and I read the first chapter but then stopped.
The thing is, because this book has so much history of cryptography/cryptology it is amazingly current.
I've read quite a few books now and this one really covers the entire history of codes and cracking codes.
It's actually even better than I thought it was going to be.
Have you read it? It's absolutely fantastic.

It looks very interesting. Cryptography has long been an interest of mine. The second program I ever wrote was handling a simple substitution cipher in BASIC on an HP 3000 using a Teletype. That was in 1974.

If you've written an algorithm like that, you'll definitely enjoy the book.
About 14 years ago I wrote little encryptor which used XOR to "encrypt" and "decrypt" user data which was then saved as Hex bytes in a file. It was a silly thing just to make sure the user didn't screw up the data. But it also taught me a lot about how difficult it is to create true encryption and how easy it is to decrypt data.
Also, as you read the entire history of encryption in this book you will discover that basically everything has been hacked by applying frequency analysis and the point there is : Randomize your data!
Easier said than done.

It sounds very interesting. 
Several years ago I revisited that simple cypher and adapted it to encrypt our application's user permission file and it worked pretty well.

A couple of threads earlier I asked the question: Should one defrag a SSD or not. I got different answers so I tried an experiment:
I am very familiar with Macrium Reflect to create images of my C: drive, which is a NVMe M.2 SSD. Reflect works extremely fast and will create an image as fast as the C: can feed it data.
So I created a system image and noted the speed at which Reflect was writing it to the target. It reached a maximum speed of 6.7 GB/s. Then I ran "defrag C:" from a command prompt and got a report that the C: drive was 20% fragmented before it was successfully defragged.
Then I ran Reflect again and this time it reached a maximum speed of 7.8 GB/s!
It seems to me the speed at which SSD can read large volumes of data is affected by fragmentation.
Note: I ran the trim command on the same drive yesterday and it seems this did not remedy the fragmentation.
Thanks to all those who expressed an opinion on SSD fragmentation, but I will be running it from time to time. If that shortens the life of the SSD, well, they are cheap and easy to replace!
Note: Windows reported as follows after defragging the C: drive:
Pre-Optimization Report:
Volume Information:
Volume size = 930.65 GB
Free space = 868.64 GB
Total fragmented space = 20%
Largest free space size = 863.72 GB
Note: File fragments larger than 64MB are not included in the fragmentation statistics.
The operation completed successfully.
Post Defragmentation Report:
Volume Information:
Volume size = 930.65 GB
Free space = 868.64 GB
Total fragmented space = 0%
Largest free space size = 863.75 GB
Note: File fragments larger than 64MB are not included in the fragmentation statistics.
Ok, I have had my coffee, so you can all come out now!

The only reason we used to use the defrag tool was to watch the animation of the blocks being moved around.

Did you run the tests more than once before and after the defrag?
|
|

A valid question! In response to your question I just now ran the "after" test again and got the same result. The "before" test I ran many times over the weeks and never got the speed that I am getting now.
Also: I did a clean install on the machine 3 days ago, and this may explain the 20% fragmentation.

People that pretend to be experts claim that since there are no mechanical parts in an SSD that fragmentation is no longer an issue clearly do not understand how software for a file system can also be a bottleneck. But the fact is, nobody verifies anything and just repeats crap.
That being said, it's much less of an issue these days. Back in the day if you had a fragmented filesystem... you would know. SSDs work substantially quicker than mechanical drives. In theory the speed of electricity. It's still a tradeoff between defraging and a shorter lifespan of the drive though. I mean they're much cheaper now and last a long time, still worth knowing about the tradeoff.
Just a tip to keep the FS from fragmenting. If you have a bunch of files that you move around a lot you can always dump them in a zip file that's lightly compressed. It'll spare your real file system. Granted, probably better to do this for tiny text files that aren't source controlled, so maybe it's not practical.

So I have this Ferrari Daytona SP3... and I was wondering if I could use jet fuel instead of gasoline. I asked online and most people suggested that jet fuel was probably a bad idea since it would likely shorten the cars life. I decided to test it at the track and discovered that using gasoline got me from 0-100mph in about 5.8s and topped out at about 210mph. However, if I used jet fuel it got me from 0-100mph in 4.7s and topped out at 242mph.
Awesome! I'm sticking with jet fuel!! Never mind that I live in the city and my average car trip is less than 3 miles (round trip).
Bottom line: Not sure that using Macrium Reflect is the best judge of your real world system performance. Just saying...

Since I use Macrium Reflect almost on a daily basis, it is a valid metric for me. I will continue doing what is best for me, and you can do whatever works for you!

Of course... BTW - I was joking with my "analogy"; hence the "joke" icon of my post.
Out of curiosity, what role / function does this PC perform that necessitates such heavy use of Reflect?

I keep my data on a separate drive which I backup separately, so the C: drive only has Windows and the applications. So my Macrium images take less than a minute to create. Since it hardly takes any time, I take an image every morning first thing and I can restore my machine to a previous state if I pick up anything nasty or unwelcome.

So if it slowed down by say 10% then that would be too slow?

Ultimately that's all that matters, doesn't it.
If you have a measurable difference in performance, stick with your current method.
