Re: Bits and PCs - a Computers and Tech Miscellany
Oow thanks I meant to actually reply to this!
A multimeter is a must, and unless they’ve updated them in some way since I started electrical stuff, a second multimeter or extra multimeter fuses as backup for if/when you run current through it on the wrong setting and fry it while fucking around, but being able to tell if and how things are flowing in a way besides touching your tongue to it is crucial. Soldering irons are good to be able to fuse wires together but twisting is enough for breadboard type stuff.
An oscilloscope isn’t needed for basic breadboard type stuff, but if you’re excited and throwing around money, it’s a great tool, especially for learning and diagnostics. Think of it like an electronics microscope. I lost at least a few lunch breaks in high school once I found out the Oscilloscopes could let me see things like what a keyboard and mouse was actually sending down the cord among other things.
Re: Bits and PCs - a Computers and Tech Miscellany
Yes, looking at micro/nanoseconds is fun, but if there is anything that changes with time, you need an oscilloscope, otherwise it's all guesswork. It's not about throwing money around either, you can get a used analog one for 30-40-50 dollars/euros from ebay or wherever. A brand new digital scope will cost maybe 400 dollars and do everything you want. You want to know if something switches on and off? The multimeter will tell you "maybe".
Re: Bits and PCs - a Computers and Tech Miscellany
The first one I got from ebay and it was a Hameg 312 from 1969. 40 euros and it worked perfectly. Analog and only one channel so you couldn't compare signals, freeze or save them, but the instant response was great.
Re: Bits and PCs - a Computers and Tech Miscellany
Silly me did not pay attention to what I was doing when I coded MySQL queries in PHP using Dreamweaver...nor did I look at what version of PHP the web server was running...so now I have to a) reboot the server to apply updates, b) update to the latest PHP (server is running 5.5.x! ) and c) migrate the PHP I've written to ensure that it actually works using PHP 7.x...
When means very late nights to avoid prime-time disruption of services.
By the time I get out of this noob programmer phase I will be ready for retirement.
So anyone got any helpful hints?

Have you cleared your cookies?
Which is to say, no, but I sympathize. I just had a super-mini version of the same type of cascading update thing, but mine was just my computer/home server, so the stakes were low and nobody had authority to be mad at me about it.
Re: Bits and PCs - a Computers and Tech Miscellany
Spent a few of the wee hours testing and updating the site on my laptop using MAMP running PHP 7 and when that was all good, updated the real site and so far, so good.

The three major credit reporting agencies use dynamic KBA to identify people requesting their credit reports online. Financial institutions use it a lot too.
A week or two ago, I saw a little jokey game thing that was going around asking people about different cars they've owned. That is one of the most common questions used for KBA, but hey, I'm sure it was a cute and fun little personality test or whatever.
Normal people: Waaah halp me somebody stoled my identity.

This is your monthly reminder none of your data is safe, and most companies don’t care.
Data breaches,
Do you use DoorDash? 4 million accounts had their data leaked, many included address and last 4 digits of the used credit card, along with hashed passwords.
Do you play Words with Friends or other Zynga games? Basically the whole Zynga database of some 200 million accounts got scrapped. It as well includes hashed passwords.
The same Zynga hacker has claimed they’ve stolen from some 40+ companies, but also appears to be having trouble moving the data for the $$$ he wants.

Twice this year I've gotten "sorreh, we let someone get your data" letters from companies I have accounts with. They both came with offers of free subscriptions to security tracking. I didn't bother to take them up on the offers, probably should do so. It just kind of sucks knowing you're at the mercy of dumb luck, basically.
