storyinmemo··on Tech workers remain some of the highest paid in New Zealand
Good heavens I'm feeling this. With my last few employers being acquired by private equity or having layoffs my resume doesn't scream, "Will grow in the role," anymore... and it didn't have the chance to do so.

Things are rough out there for sure.

storyinmemo··on AWS to begin charging for public IPv4 addresses
The 0.045/GB of NAT transfer cost is in addition to the $0.09/GB egress costs.

You should look into temporal.io. Your workflow problem is highly suited to it.

I wish my appliances would just implement Zigbee or MQTT in open way.
storyinmemo··on Cirrus Vision Jet Pilot Pulls Chute in Florida
In docile trainer aircraft the spin can be recovered from, but that's usually only allowed to be tested in the utility category which has more restrictive weight & balance limits. In famously efficient airframes, it can take several thousand feet. In this article, the famously hard to insure pilot killer the Lancair IV took 4,000 feet: https://www.kitplanes.com/taming-the-lancair-iv/

Part of the Part 23 (certified aircraft rules) process is demonstrating spin recovery. The Lancair is experimental so it's not Part 23. Cirrus said, "We put in a parachute instead of demonstrating spin recovery." To which the FAA said, "OK, that works for us."

Since the Cirrus prohibits spins (most certified aircraft do) and Cirrus never demonstrated it officially, I only have the word of random comments on the internet to go with. The assumed state is, "The SR22 has poor recovery characteristics from spins and the manufacturer states in the POH that CAPS is the only recovery method." Maybe it's not all that bad, but at pattern altitude (this has sadly been demonstrated) I'm sure it's fatal.

storyinmemo··on Why Japan's rail workers can't stop pointing at things (2017)
Flight instructor here and I've totally adopted teaching that. Touch or point because it does happen where you reflexively say something like, "Gear, Down"" and... it's bad if you're wrong.

Airlines (which I don't have personal experience with) do it with a two person cross check.

storyinmemo··on A French town where the lighting is alive
Cycling infrastructure costs far less. Road damage is roughly the square of the vehicle's weight. Also, we don't charge pedestrians for sidewalks.

> "Increasing a truck’s weight [from 80,000 pounds] to 90,000 pounds results in a 42 percent increase in road wear. Pavement designed to last 20 years wears out in seven." https://urbanmilwaukee.com/2017/06/22/murphys-law-how-trucks...

> It would take 700 trips by bicycle to equal the damage caused by one Smart Car. It would take 17,059 trips by bike to equal the damage caused by an average car. And it would take 364,520 bike trips to equal the damage caused by just one Hummer H2. https://streets.mn/2016/07/07/chart-of-the-day-vehicle-weigh...

When this all comes together, every cycling trip I take is a car left parked and that benefits everybody. That's why we don't tax cyclists for infrastructure and why it's counter-productive to raise it as an issue.

storyinmemo··on The Factorio Mindset
Hi, it's me your local site reliability engineer. I care about things like latency, monitoring, and being able to understand the overall moving pieces. Scaling things in appropriate ratios is also relevant to me. I'd put you in a storage box and nuke if I could, but let's go have this conversation standing on these train tracks.
storyinmemo··on U.S. FAA clears 45% of commercial plane fleet after 5G deployed
To be instrument rated (all airline aircraft), composite aircraft must have a metal weave in the outer layer to dissipate static electricity build up from flying through clouds. This preserves the faraday like signal reduction as a side effect. My phone's GPS seems to struggle bus as much in a 787 as any other airline.

storyinmemo··on Interview with CEO of Flexport: Supply chain crunch, modern logistics
Spewing BS doesn't in this context seem to imply either lying or shilling for somebody else. It's a devaluing the opinion of no taxing the rich, and being disappointed at the expression of that opinion.
storyinmemo··on Airports Had to Deal With Over 2B Litres of Airplane Toilet Waste in 2019
I fly small planes and I'm usually into a snack bar before I level off. I do try to make one liter of water last the whole flight, though, which can be up to 5 hours.
storyinmemo··on Some Apple engineers rewarded up to $180k in stock bonuses as incentive to stay
Honestly it's a game to identify which. Accidentally left my garage in an 8 unit apartment building open once. Had to clean up the poop 15 minutes later.

Human, if you're wondering still.

storyinmemo··on The 3-2-1 Backup Rule – Why Your Data Will Always Survive (2019)
The cost of the tapes isn't what keeps me from having it home. It's the cost of the tape drive.
storyinmemo··on Buying an ebike
As a cyclist (several of them, most often either a Trek 1.5 and Tern Vektron) and motorcyclist (700+ lb Concours 14), the bicycle is scarier. The motorcycle's weight isn't an issue in a tip or slide situation, and I can wear pretty serious armor in all weather conditions.

The bicycle leaves me exposed in traffic and more often than not wearing a t-shirt for heat control.

Just to give a different perspective on it.

storyinmemo··on The U.S. Treasury is buying private app data to target and investigate people
As I understand it, that's not quite true. I can't get a phone provider that won't pen register my data off. It's not an option and it's entirely not practical to conduct life without a phone of some kind.
storyinmemo··on We saved millions in SSD costs by upgrading our filesystem
This is where RocksDB or other SSTable storage systems really line up well with SSDs. The write amplification reduction can improve throughput and disk life by multiples.

storyinmemo··on I’m not a pilot, but I just flew a helicopter over California
I'm trying to imagine any computer that would have coped with my IFR search and rescue flight last week. Non-standard requests and things that can't be seen by ATC affect things a lot. One other silly small example that feels complicated was requesting a visual approach but having to wait for a vector because there was one exactly-airport-shaped cloud in the way.

I think pilots get a lot of situational awareness as well from listening to the common frequency.

storyinmemo··on Belgian ISP under 250 Gbps DDoS for days on end
It's like a large city in a way. Most of your roads are local, and so is most of your traffic. You try to distribute load and makes trips as short as possible. For a city its grocery stores in neighborhoods.

For an ISP, they do this by peering locally with major providers. Google, Twitter, Facebook, Netflix, etc. all have very large networks and will openly connect at Meet Me points in open and private internet exchange sites as will CDN providers. https://en.wikipedia.org/wiki/Internet_exchange_point. Some providers such as Google and Netflix will even install local caching servers that you can reach from your network if you have enough traffic. As a small ISP, you try to take advantage of all of that.

Your option of last resort is the Tier 1 upstream provider. That's for anything where you can't get to it via local transit peering. This should be a smaller percentage of your traffic and it costs more than peering arrangements. The nature of a DDOS is going to fill that smallest and most expensive connection that provides the filler access to the majority of the world but doesn't handle the majority of the traffic.

Even as a hosting provider, it doesn't have to be overselling. If you have 250 1Gbps customers and 250 Gbps of bandwidth, you'll still be useless in the face of 250 Gbps of junk traffic. Pick a random packet and tell me what should decide if it is dropped is something that has to be determined upstream of the saturated link.

EDPnet looks pretty well-connected too: https://bgp.he.net/AS9031#_ix

storyinmemo··on Solar is dirt-cheap and about to get even more powerful
No, or at least not without more steps and automation. WAY back before refrigeration, cooling was done with blocks of ice harvested in winter and stored for the year. Expensive is a word for it.

What's being talked about here is thermal energy storage. Ice is created overnight (ok, like a refrigerator), but then during the daytime used to supplement or replace the refrigeration cycle of the compressor to reduce electric load while still providing cooling. I can't quickly find an article (edit: found a 2016 paper, see comments about Boothbay on page page 3-4: https://www.aceee.org/files/proceedings/2016/data/papers/3_2...), but it's memorable to me that an island in Maine installed these systems instead of spending more on replacing the distribution line to the island the handle the peak daytime cooling load.

storyinmemo··on Nvidia Unveils GeForce RTX 30 Series GPUs
A rough inflation guess is 330 six years ago is 363 today. The 3060, which is still a relative monster, will set you back 400.

My last gaming computer took me 9 years along with only an SSD addition, RAM upgrade, and video card change halfway through. It was only Microsoft Flight Simulator that made me jump up and damn... my timing was a just a little too early on the beefy video card.

storyinmemo··on In Secretly Recorded Phone Calls, Officers Say Innocent People Were Framed
American military doctrine is about being the superior force via tactics and equipment, being able to easily dispatch a larger or less trained enemy.

American policing has inherited this idea.

storyinmemo··on A Google Cloud support engineer solves a tough DNS case
My fleet of machines I was the owner of at Facebook was around 10,000. I still remember the odd JVM crash that prompted me to reimage a machine. I wouldn't have remembered it except there were a few that month and it was the 3rd time I reimaged the same machine that I thought, "That's odd... I think I know that machine name." Checked history, saw the 3 repair jobs I had submitted... RAM was reset, CPU was eventually guessed at as bad.

Cattle is a threshold, but when the same problem keeps coming up it's time to call the vet. http://rachelbythebay.com/w/ has many good examples of this, some submitted and voted up here.
