Oh man, this brings back the days when I wrote special debug-version malloc and free code to try to track down heap corruption due to malloc / free misuse (in code I had contributed to). Stuff like kbyte-long boundary buffers with bit

I'm working on comparisons between redis and SQLite for object caching. So far things look favorable. I did this project for WordPress, because object caching helps performance (and therefore carbon footprint) a lot and cheezy hosting

The clustered primary key (NO ROWID) setup that came in with SQLite version 3.8.2 (2013-12-06) makes it very fast indeed when used for a large persistent key-value store. And later improvements have just continue to accrue. This from a guy

I went with SecureCRT because it had its own well-done terminal emulator back in the mid-1990s when I started using it. It's evolved nicely ever since.

OpenSSH is indeed widely used. But the only game in town they're not. There are commercial SSH implementations that aren't based on OpenSSH, reasonably widely used too. For decades I've used a Windows product called SecureCRT

I have to say, I understood what this is really fast when I saw the README. It's really a great idea. I'dve been all over it before I :-) :-) retired. It's going to save growing companies a fortune, by helping cancel prompt

My experience of this is interesting. When I'm writing code I care a lot about, I don't have to worry about DRY stuff, because I can't really write the code without figuring out the right abstractions. It starts DRY. But when

I'm certainly not crying "Woe is me." Not at all. SVB, and other parts of the business, worked out very well indeed for us and our employees. Did scramble to make payroll a couple of times, but that was nothing to do with

Regulatory capture, it's called. Man, it does a lot of damage. Long ago I and colleagues opened accounts at SVB for two different outfits with VC money. It was simply the thing to do when getting started converting that money into soft

Dredging up my old college math. A mathematician named Kantor proved that the number of rational numbers (fractions) of postive integers is the same as the number of positive integers. His proof involves COUNTING the fractions. And that kin

tl;dr referers from web server logs. Simple is sometimes best. And, ya know what, you don't need to spend a lot of money or time in the complex surveillance economy to look at your logs for bigco.zoom.us and that kind of referers.

I've spent a good chunk of a half-century-long career, now winding down, doing the kind of work our author describes. Most of it was on my own initiative. I'd notice some kind of anomaly in the logs of whatever app I was working o

My brother the academic librarian / archivist has, for many years, been warning about this kind of obsolescence. It's necessary for we software folk to ask ourselves "two centuries from now, how will people make sense of our

Script kiddies doing vuln probes. Definitely not worth much of your energy to try to figure out root causes. For what it's worth, if you activate the Akismet plugin that comes with WordPress, you'll get Automattic's crowdsour

I worked for a B2B SaaS outfit which charged by month by seat. Some customers demanded usage-based charges and our sales and PM said yes, without checking in with dev. As the guy who knew the app's logs best, it fell to me to code up a

A weight discrepancy of ten to fifteen TONS???? That's no small mistake. It's not a rounding error on the weight of the soda cans loaded into the galley for the flight. That's most of the passengers. It's most of the fre

I sailed on that fine ship several times, before the Boeing 707 era, as a little kid. My dad was a junior diplomat at the time and so he and his family traveled "cabin class". The classes were "first", "cabin"

Good. Invent things. Try things. But keep this in mind: plants evolved lignin to make their structures (trunks, branches, all that) hundreds of millions of years before bacteria and other microorganisms evolved the ability to break down tha

The client-server wheel of life just keeps turning, and turning, and turning. It's an eternal human truth: each generation yearns to improve on the previous generation's efforts. This server-client zeal to improve has been tremend

HEY! Before you adopt this check the bandwidth egress costs! Seriously. Your disaster recovery plan will need to budget for extra egress costs if you ever need to restore something big from one of those virtual tapes. AWS charges for egress

With respect, calibrating compass compensations is in fact very important in FAA approved aircraft. It's part of the inspection checklist signed off by the licensed mechanic. My flight instructor once switched off the electricity to th

And I thought a four-hour flight I once took in a 172 was far too long! Good little airplanes, they are. I suppose they chose their engine airspeed to achieve the lowest fuel consumption rate https://www.se.edu/aviation&#x2F

It's not quick money, but writing books can generate an ongoing royalty stream. And, they're good resume builders if you want to do freelance work. It worked for me. You can do worse than O'Reilly Media. https://ww

The internet has this kind of stuff too. Addresses "reserved for documentation" by IANA / IETF. I don't remember seeing them mentioned on-screen. I guess it's easy enough to register ghostbusters (dot) info or what

Interesting. Honda's core competency has long been internal combustion engines (ICE). My household has, for a long time, had a Honda car, motor scooter (110cc), and lawnmower. We don't need a generator, but if we did we would pick

A long time ago -- late 1980s -- I worked in system software, VMS-based, at DEC. Sometimes we used, for dev and testing, dedicated machines running with clocks set 20-25 years in the future. (They was a measurable investment of capital, pow

This answer to your question is more about scaling out (many machines) than scaling up (big machines). Many budget hosting providers supporting CMSs like WordPress and Joomla run very large multitenant MySQL or MariaDB instances. These inst

This is great. Especially because it's the work of a highly motivated and gifted person who doesn't crank code for a living. I'd say "gifted amateur" except the only thing amateurish about this is that it's a l
