mNovak··on The Best Pens for 2023: Gel, Ballpoint, Rollerball, and Fountain Pens
Wow, I'm shocked at the level of depth in this site. I thought for sure something like "best pens for your lab notebook" would be SEO drivel, but they actually test against things like alcohol and acetone, and consider writing on vials and containers and such.
mNovak··on Money market funds swell by over $273B as investors pull deposits from banks
You can paste the pw into the field if you edit the html!
mNovak··on Comparing Hobby PCB Vendors
It has very low loss (more than 10x less than FR4), and low dielectric constant, and both stable up to very high frequencies
mNovak··on Arduino Uno R4
I agree, considering that much of their marketing surrounds DIY automation and they have this whole IoT cloud platform now, they very little support for low-power operation. In this regard I think Adafuit and Seeed platforms do much better, while still being very beginner friendly.
mNovak··on Comparing Hobby PCB Vendors
I've placed probably 20-50 orders through JLC. Very consistently decent quality, and surprisingly good customer service, they manually check every design within a few hours and will email with issues and/or their adjustment.

Tip for smallish boards: "Panel by JLC" can further drop the price. It's often cheaper to buy say 10 units of a 2x2 panel than to buy 40 individual boards.

I was stunned to see they added teflon substrates recently (for RF layouts. I've paid $1000s for teflon fab); very excited to try that out.

mNovak··on Reasons the banking crisis isn’t a repeat of 2008
If anyone is interested, as I was, data up to 2019 comes from [1].

Note that it's plotting medians of those who hold the asset, so i.e. "non-residential real estate" (held by 7% of households) is median $70k.

mNovak··on Banks with the highest risk of collapsing according to market data
This seems like largely a ranking of what banks the market is currently pricing in for failure (via share price and P/B). Still interesting, but maybe not really based on the banks fundamentals, just 'market wisdom'
mNovak··on Kenji López-Alt spent 5 months studying Chicago thin-crust pizza
I use store-bought pitas, sliced in half (thickness-wise, takes some practice). Very easy, and gets nicely crispy.
mNovak··on Mountpoint – file client for S3 written in Rust, from AWS
In a similar vein, I've been using ExpanDrive [0] for a while. Though admittedly it's only suitable for infrequent access / long term storage type use.

mNovak··on Punctuation Matters: How to use the en dash, em dash and hyphen
My opinion on this matter is entirely driven by the fact that I got used to easy '--' and '---' en/em dashes in LaTex. So now when I use Word, I added autocorrection triggers for '--' and '_-' to the same effect.

But, it makes this whole em dash-filled thread very confusing to read as everyone (from my viewpoint) is using en dashes (--) where em dashes belong!

mNovak··on Lessons learned from 15 years of SumatraPDF, an open source Windows app (2021)
I use N++ everyday and do love it; though I recently found out that it completely freezes trying to open modest sized single-line json (couple MB), which made me sad.
mNovak··on Scaling to millions of users with Google Sheets as a back end
I guess I'm confused, if you're already running Cloudfront, API Gateway, and lambdas, why you'd bother to make API calls out to Sheets rather than just plunking down a simple DynamoDB? Maybe the data access patterns are more complicated than I'm thinking, or just to capture the built in Forms -> Sheets data entry flow?
mNovak··on Nokia launches DIY repairable budget Android phone
Maybe I'm a luddite with my 2017 phone, but what's meaningfully changed in smartphones in the past 5yrs that Apple is setting the bar on? (Besides pushing screens to the bezel, and the cameras multiplying)

mNovak··on Gigapresses – the die casts reshaping car manufacturing
Actually surprised no one is taking up the "gigagram" 9Gg moniker
mNovak··on Ask HN: What's with the DIY state of the art long-range Wi-Fi?
I'm not very familiar with Freifunk, but if it interfaces like a normal WLAN to the user, then simply not advertising SSID and a basic password will go pretty far. This is obviously not secure against any sort of special operative, but eliminates it as a very easy convenient tool for e.g. a mobik with a cell phone, if this finds its way anywhere near a frontline.

An upside of highly directive, P2P links is that they can provide some protection against EW, simply by nature of having a constrained field of view. Also I'll note most consumer devices (laptops, cell phones) have pretty bad antennas, they're assuming you have a router right nearby. You might get much better coverage if you're also able to provide the user with a simple USB dongle that can attach to an external antenna (e.g. a 10dBi yagi-uda)

If there is need for any input on the antennas side, I'm more than happy to help (EM PhD, design antennas for a living). 2.4GHz is relatively forgiving, you can literally hand make antennas, with some attention to detail. If you have access to shipping (I really don't know the situation) they can be mass produced on PCB.

mNovak··on Buy hi-resolution satellite images of any place on earth
There's been heavy use of these kinds of services for exactly this purpose. See [1] for example. Typically airbases, mass graves, bridges; things we know won't move or change too fast.

mNovak··on An Open Letter on the Open Gaming License, to Wizards of the Coast
Not a lawyer, but my understanding last I looked into it was that names and rules cannot be copyrighted (names can be trademarked though). In very limited cases a novel mechanic could be patented (famously MTG 'tapping' of cards). The issue overall is that no one wants to risk it in court, so there's no recent precedent to take inspiration from.
mNovak··on Why are antennas popping up over the Salt Lake City foothills?
There are some Helium nodes along the SLC foothills [1], though I'm not seeing many so remote or far from a road. Unclear if this displays history or only active nodes.

mNovak··on Tell HN: I just received my Equifax breach settlement check
>> How do people determine which ones are real

You can in principle look up the case numbers that should be present in the court documents explaining the settlement. Alternatively you can look it up in a public database such as [1], (also a good way to find suits you qualify for, if you so desire).

mNovak··on Open Source SMT Pick and Place Hardware and Software
This is very cool, thanks!

According to the site, it does in indeed run openPnP

mNovak··on Recursive Game of Life
I got that error in Brave until I turned off the blockers
mNovak··on Open-source tabletop board game simulator
This is really interesting, never saw that before. I've long been thinking of starting a hobby project for a general purpose board gaming rules engine. Guess it's already there!
mNovak··on Ask HN: What weird technical scene are you fond/part of?
It is really strange how this is a niche now (the frameworks); a couple lines of JS to handle button clicks is fine with me (again assuming you're not downloading jQuery for it)
mNovak··on Ask HN: What weird technical scene are you fond/part of?
I recently got involved with a community which organizes table-top wargaming rules/profiles into machine readable form. Some of these games have hundreds-to-thousands of units and special rules, so it's quite impressive what emerges.

mNovak··on Show HN: A color picker for named web colors
Very cool. Also this reveals the secret, that brown is dark orange!
mNovak··on FTX Owes Money to More Than a Million People, Court Filing Suggests
Everyone is making a big fuss over the complex corporate structure, and while suspicious, it's also not totally out of the norm. If you've ever seen real-estate syndication deals (another activity with many investors over varying classes), those regularly have a web of dozens of entities just to wrap around a single property.
mNovak··on How Regexes Work
Curious if this exponentially slow regex is the reason Notepad++ crashes on loading modestly sized (10 MB) JSON?
mNovak··on Zuckerberg's leaked email on VR strategy (2015)
This is largely what every sci-fi film has predicted. Though, I don't really see the value of my cell phone being see-through, beside it looking cool.
mNovak··on Show HN: All-SVG websites with complex animation
Personally, I think this is incredibly impressive! It feels much more like reading a magazine than a fixed info-port. Given, there's a time and place for both, but it's always nice to remember the web can be about creative expression.
