[Excentro](http://www.excourse.com/excentro/) is fun specialized software for creating guilloche or "Spirograph" vector designs like you might see on bank notes and contracts and such. You can bring the results over to your vector program of choice to integrate into a composition.
I do quite often, both because my content addiction requires more than the front page provides and my vanity likes the idea that my comment will be read by a lot of people if the post makes it to the front page.
I like the idea of the bug database synchronized with the code base, becoming part of the documentation, but here are my concerns.
Often people who are not developers put "issues" into the bug tracker and they might not find working with the command-line easy.
If an instance of the system is in use by many, debugging a problem experienced by a particular user might involve personally identifying information which should not be checked in with the source.
Also issue trackers sometimes deal with multiple branches of development. In a sane place you might have 4.8 and 4.9 in production and a 5.0-dev, fix a bug in 4.9, then port the fixes to the other branches. To do this you are thinking about the tree as a whole and that's easier done from outside rather than inside the tree.
I think at a certain point you can only really act on <10 ideas and see them through in your entire lifetime. I would probably only give credence to ones that you think you'll realistically spend 10 years on. Even if you don't end up doing so, it's a pretty strong filter to get rid of junk.
I wrote two free books specifically on productized services.
The first book discuss how to productize your services and hire and manage remote workers (and it covers the tools and techniques to work remotely). The second book is mostly about value proposition and marketing.
So you’re not trying to maximize salary but care about equity? Not sure I understand. Equity at seed stage startups is like buying lottery tickets, with the main difference that even if the startup has a successful exit 5 years later, you are not likely to get much if you are a salaried employee. Say you get $100k salary and 1% of shares, which becomes 0.1% after dilution. Say the company is bought for $1B. You will get $1M. So the total you have made after 5 years would be $1.5M. If you were working at Facebook at $300k/year you would have earned the same amount. Only the chances of this happening at FB are close to 100%, while unicorns are called unicorns for a reason.
The best setup acc to me for web is Firefox + uMatrix + CanvasBlocker + WebRTC Blocker + DecentralEyes + HTTPS Everywhere + Smart Referrer + StartPage / DuckDuckGo + any DNS over HTTPS provider of your choice. Be prepared for the recaptcha time sink. You could turn on Firefox's resistFingerpriting setting, too. Use Brave or Bromite as an alternative browser for websites that break.
For phones, you could run DNSCloak with AdGuard DNS (iOS) or Blokada (Android). There's AdGuard Pro, Lockdown Firewall, and Guardian VPN+Firewall for iOS that are super neat.
NoRoot Firewall, NetGuard, and GlassWire Firewall for Android that I've found to have acceptable privacy policies. LittleSnitch or LuLu Firewall for Mac, GlassWire Firewall for Windows are some of the other options.
Pi-Hole your routers too for other devices connecting to Internet.
Inserts would be in the hundreds to thousands max <10k a second tick data spread across <100 symbols. I generally only focus on 10 at a time but upscaling the window there for historical needs.
I never studied business, but did spend a couple years as a product manager working with MBAs, and what I was told --- this could definitely be wrong --- about business degrees and, more importantly, business school is that most of the value was in physically attending and networking, and that you generally wanted to be in one of the top programs or not do it at all.
On the other hand, I have heard from other people that accounting classes are super valuable.
I already addressed your question in another comment, but I would like to write a second point: a book seems to me the wrong way to go.
Unless your friend is a natural born comp. scientist, she'll need someone to point out what's important, what's not, which exercises she must solve before moving on and which topics she can take in parallel if she needs a break.
Of course, a course takes time. But if someone doesn't find the time to take an online course, where will they find the time to (properly) read the book?
I set up my own FreshRSS instance and am adding more and more feeds to it. I found that suitable to give me a broad overview over news etc. But you will have to look for sources on your own, that's maybe a problem. Also less and less sites are using RSS/Atom.
I wonder about the "you are now free to delete the certificate". Not everyone will do this if they aren't tech savvy enough, or don't care. This will mean 2 things 1. Those that don't may still be able to have their traffic intercepted 2. Those that do reject the signing (if the attempt is made) may find themselves the subject to further investigation.
