Recheck your credit card. I suspect what you saw was the "approval" check to verify funds. I suspect the actual charge is not on your card (Federal CARD Act).

I thought that would be the case too, however, the charge was completed and I've already paid the cash to the card too (paid bill off). I thought they would just put a $100 charge or something on there but it was the full amount.

I don't know about Federal Law, but over here in the UK, your contract is with the credit card company. So you can demand your money back if you have not received the goods, and they have to reclaim it from HP.

Thanks for the info. Good to know. Thumbs Up | :thumbsup:

Well you know HP stands for 'Highly Priced' I have had two of their printers, good unitl they burnt out (or you had to buy new ink for them). I have a HP PC I got off Amazon for not too bad a price, had a couple of heat issues with it. If I'm paying I would not go for Computers/Printers from them, lab kit yes, home kit no! Big Grin | :-D

I agree with you but this was the low-price leader on my laptop.
Only $622.95 with
AMD R7 chip
16GB Ram
256GB m2 drive (kind of smallish)

I bought my wife an HP a few years back (i5, 8GB) and it is still running quite well too. Had good luck so far.

I'm a cheap-skate and anything else comparable was breaking $1000 and more.

They wanted that quick on the books before new years. Yours and anybody else ordering late in the year. Many of our clients order then to ease their income tax burden, and trade it in for the abomination that today's laptops are. The plastic has gotten so brittle.....

I always build myself. Warranty service (me!) is reliable that way. And I can only sue myself if delivery is late.

Me too. I bought all my components for my desktop at MicroCenter and put it all together myself. The first time I had a bad mainboard but I just took it all back and now this fantastic machine has been running for almost 2 years now. It's way better.

but I can't build laptops. Laugh | :laugh:

I only order from Dell. However, a month or so ago I advised my daughter-in-law to order her new laptop from Dell. Dell had to ship her three computers! First the first unit mysteriously disappeared from the truck of the shipping company! Then the same happened to number two. Finally the third one arrived. I wish I knew what Dell had to say to the shipper! They lost money on that deal! D'Oh! | :doh:

Get me coffee and no one gets hurt!

strpbrk() in Microsoft's VCLib is *slow*

29-Jan-21 11:34

Wow, that is crazy it took 3 tries. You'd think Dell would investigate. I guess it's just a write-off.

Two rants in an hour. Geez

Turns out (from the looks of things, unless i messed something up) strpbrk() is poorly optimized in Microsoft's VCLib.

I'm only getting <500MB/s in JSON(C++) on a windows machine compiled with cl.exe:
cl.exe /Zi /EHsc /nologo /GL /D "NDEBUG" /O2 /Fe:main.exe JSON-CPP\src\main.cpp
(I never use cl.exe from the command line so maybe it's wrong?)

On linux on my old machine that was 20 times slower than this one i was getting almost 600MB/s on a standard HDD on an old i5. But that was linux. This machine is a Ryzen 7 on an NVMe drive. On windows.

And yet? WTH!

Does anyone know if GCC will work on Windows without some virtual env like MiniGW installed?

If something has a solution... Why do we have to worry about?. If it has no solution... For what reason do we have to worry about?

That's the opposite thing, I think?

This would be running a linux based app on a windows machine, not the other way around.

I meant GCC. my app should compile just about anywhere - even on 8-bit machines with no real operating system to speak of.

I'm gonna play dumb:

What are you getting as JSON files, that is so large that processing half a GB of it per second is a problem?

I'm old-school, so I'm all for optimization. However to put things into perspective, 500MB is something that would take my internet connection a significant amount of time to download. Having some C++ code chew on a JSON file that large per second isn't necessarily what I'd be terribly concerned about.

Searching and uploading bulk data, from JSON files, often in line delimited JSON form (each json doc on its own line in one big file)

Still playing dumb:

And JSON is the correct mechanism for this?

honey the codewitch29-Jan-21 10:38

29-Jan-21 10:38

Ask the people that produce these files.

Do you plan on insisting that they should move to a binary format?

Good luck!

Like I said, I was just playing dumb. I fully understand that some of these things are probably out of your control.

honey the codewitch29-Jan-21 12:26

29-Jan-21 12:26

Fair enough. Yeah, JSON is used for big data for better or worse, like XML was. There are *some* advantages to a lexical format when it comes to transmitting numbers across platform, but nowadays the binary representations are so standardized anyway that aside from byte order it doesn't matter. But people will do what they will do.

It's probably not the compiler so much as the supplied libc. You could peruse the source for glibc and try to write your own strpbrk() based on that. Though the odd occasion that I've tried to spelunk through the glibc sources, about 50% of the time it becomes a bit like trying to solve a maze in Zork. And, of course, it raises possible GPL issues, so maybe looking at the BSD sources might be a better choice.
Wasn't there a post a few weeks ago bout SSE and string ops? Maybe that's a direction to consider if you want to write your own.

On a related note, it might be interesting to see how a WSL instance compares in performance to a Windows native instance. The results of that might be skewed though, if WSL uses virtual disks, so maybe a better comparison would be Linux and Windows, both in a VM on the same host. At least then both instances would have the same virtual disk drivers, so, presumably, the difference would be down to the strpbrk() implementation.

i was the one that brought up the simd string processing. i may have to create my own SIMD optimized strpbrk() function for my lib just for the windows build.

Oddly enough - and I don't know if this is still true - but apple's standard libraries and OS calls were heckin fast compared to other major offerings. it was about the only nice thing i could say about them.

I'm pretty sure it's MS's standard libraries that are the problem in this case - specifically strpbrk.

I just wonder why they're not better optimized? I haven't disassembled them yet, but what i've seen of GCCs (which i *have* disassembled) it's using SIMD pretty much entirely. I doubt microsoft's is, based on the performance alone, which should be orders of magnitude faster.

29-Jan-21 6:46

Just a really dumb question. You're sure you're looking at Release build, and not a Debug build? I'm not sure that that would even matter, unless MS provides an unoptimized libc for debugging?
