Regex's predate perl quite substantially. Think grep and friends if nothing else. Certainly making the perlre library available separate to perl encouraged its widespread use, and lots of others copied or were inspired by it. "Pop

I totally agree on the "IT empowerment" perspective, but unfortunately the price model of these tools makes it hard for many IT departments to introduce them, at least in established corporate environments, for internal use. Start

While I got the 80386 programmers manual as one of my teen birthday presents.. I only ever actually did a little ASM programming but I loved that book anyway and read it a lot. Really annoyed at myself that I got rid of in some fit of &quot

Probably not much. I'd love to be wrong tho. Best possible fibre speed LA to Sydney is about 120ms. Not sure what the minimum additional latency for packet handling is.. but I did a few test.. Via one looking glass service, I get 215ms

Ha. My response to this was a very visceral "eww".. but I also realise I'm not normal. Not super keen on small talk with humans either tho tbh. I somehow fell off the tech nerd train and wandered onto a Luddite bus. I find my

You seem to have very similar races here though? Perfectly possible, even likely, for a process to end between "find" finding it and awk opening it... especially given the pipe buffer between the two. Personly I'd rather an &

The point, I think, is not how widely used it is, the point is that you become beholden to a single, often corporate vendor. I'm not actually sure what made the transition from VB classic to the DotNET version so disruptive, and so dam

I've never heard p-series called mainframe, and while it's been a while, I've both used and sold them ( as a side effect of that company's app often being sold bundled with a p-series ) While there's technically ove

"Filesystems (eg. Ext4) usually think about whole blocks, but are designed with the eye for smaller files, i.e. files aren't expected to be more than some ten or hundred blocks in size for optimal performance." Sorry what? I

Duckdb does this straight from csv. You can treat them pretty much just like un-indexed tables, including queries, joins and output back to csv or parquet. its Really nice.

I'd guess orders for these probably skew to the higher end. If you're putting workstations in racks it's either to share them, or due for power/cooling/noise reasons, and the fact that you've got a workload tha

It answers, or at least gives the definitive first clue behind a huge number of slow downs or apparent hangs, given how many of those are actually blocking resource waits or retry loops gone mad. It's probably most useful to sysadmins

Bash and zsh both allow: function /usr/bin/cat { echo hello; }; /usr/bin/cat hello So specifying a path isn't as useful as it seems

Some "new" hdds are absolutely insanely loud.. I got some recently where having 3 in an otherwise quiet case made them very audible from the other end of the house! I sent them back. Looking at the datasets for the WD Red Pro for

Can you clarify? I don't think I've ever seen such a cliff where the database is using the same query plan? There's sometimes small incremental slow downs as you pass btree depth thresholds and have to add more, but tbh even

I've moved to two line prompts everywhere as well, the second line being basically just " > " I've also added inter prompt spacing.. first that was just an extra \n before the prompt, but I decided I wanted space betw

How does this compare to something like pcie? Why would someone use on over the other?

Well, there's two very different views of reality.. And one of them appears to be from a very unhappy customer. Is it possible that different IBM Depts - or IBM regions, are selling Redhat Software/Support without much actual invo

I was a sysadmin in a windows desktops + sun/windows server env for about 10 years from 1999 I loved our sun boxes, hated that we could only ever afford their "midrange" models, and then only from grey market resellers, or ou

Right. And the the my job/work/boss sucks trope is so relatable because? There are many reasons people stay in a particular job, good and bad, but those same reasons allow for a lot of "employees neglect". You have to ne

One of the things I've had my nose rubbed in several times is just how very effective some of of those "legacy" languages - like Cobol or the various 4GL's - are for writing business systems apps. It clicked for me when

VC's probably aren't, at least not in the way you or i might, rather they're the recipient of other's investment cash. If interest rates are low, there are fewer opportunities for getting any kind of a return, so more in

This is great, thankyou. I didn't realise this had become a "thing".

Yup. This is actually why I just cancelled my netflix completely. I thought it was pretty telling that in their little "tell us why you're cancelling" they didn't have "because we cancel too many shows mid run"

I can't imagine a commercial environment where this really matters. Sub-optimal ram install layout makes minimal difference in performance one you get past "enough" for your workload - for a huge percentage of corporate workl
