eatmyshorts··on Canvas is down as ShinyHunters threatens to leak schools’ data
My daughter says that Northeastern is also affected. Is it more widespread? Did they infect all SaaS Canvas universities?
eatmyshorts··on Tailscale Kubernetes Operator
OCI registries.

Harbor + Notary + admission controllers - AKA private image repository with image signing.

Sigstore. Another method for signing & verifying artifacts.

eatmyshorts··on Lunik: The CIA’s plot to steal a Soviet satellite (2021)
It did, but only as a test. https://en.wikipedia.org/wiki/STS-49
eatmyshorts··on Show HN: DevPod – Codespaces but Open Source, Client-Only, and Unopinionated
This sounds kind of like Tilt and DevSpace, but for just general purpose containers. From a quick look through the website, I didn't see these features, but these would be great additions:

- File sync with the local filesystem and the container (2-way)

- Port-forwarding to localhost for debugging (I guess the DevPod way is to run the entire IDE in the container, but I love Tilt/DevSpace for allowing me to work in my local fat IDE)

eatmyshorts··on A cryptocurrency company had a $65M bill, per Datadog’s Q1 earnings call
This doesn't surprise me much. From what I've seen consulting/contracting, SaaS-based observability tends to cost 30-50% of cloud spend--EC2, storage, S3, RDS, maybe k8s, and other cloud services, or whatever the equivalent is on GCP/Azure. I wouldn't be surprised to see Coinbase with a >$150M quarterly cloud spend, so $65M on observability would make sense.

That said, managing observability yourself should result in <5% of cloud spend. So I'm figuring someone at Coinbase said "WTF" to this bill and migrated to Grafana/Loki or Kibana/OpenSearch or Kibana/Elastic. Well, that, and Coinbase's business also dropped off a cliff. Combined, I could easily see a one-time influx of $65M from one customer, gone the next quarter.

eatmyshorts··on The grid isn’t ready for 300M EVs by 2030
The beauty of EVs with respect to the grid is they present an opportunity to make our grid much more resilient and reliable, all while enabling renewables much greater percentages of our overall power generation. Renewables (well, specifically solar and wind) are very peak-y, with peaks that can overwhelm a grid and blow out transformers, and troughs that require additional power generation from other sources. This limits the base load power that can be generated from wind/solar to around 40% of total demand. Unless you have a way to store and retrieve power on demand. You’d need enough storage to handle roughly 2 days of power usage needs in order to smooth power usage to cover peaks and troughs. And, lo and behold, the typical EV car has enough power to cover a typical home for about 3 days!

If we incorporate inverters into home building standards today, we can guarantee that our EV fleet can be used to provide storage and auxiliary power for our grid and allow renewables to approach 100% of power generation. But we will need to deploy wind and solar in a distributed fashion so that power generation and storage is local to where the power is consumed. And a grid like this will be much more resilient to power outages and weather.

eatmyshorts··on SpaceX Starship rocket explodes minutes after launch from Texas
Watching the mission, I noticed that engines kept shutting down. There are 33 of them. When they had turned off 7 of them, with 26 engines remaining lit, it started to lose control. The engineers all seemed ecstatic about the mission. I have to wonder if they weren't intentionally shutting off engines to see how many could fail while still retaining control. If that was indeed tested, the answer appears to be 6--they can operate nominally with 27 engines lit.
eatmyshorts··on Previous: A NeXT Computer Emulator
Does it also emulate the wickedly slow I/O times of the CD/RW drive (er, Canon Magento Optical drive, apparently)? I seem to recall waiting really long for anything to read or write to that thing, despite the wonder of having a CD that I could erase, with 660MB of storage.
eatmyshorts··on System76 AMD-Only Laptop Returns
How about "The Return of the System76 AMD Laptop"?
eatmyshorts··on Ask HN: What are your predictions for 2023?
I have one about ChatGPT. ChatGPT ends up not being useful as a replacement for junior software developers. But ChatGPT does end up taking over middle management. It is more reliable, with better results than humans, at getting software updates from developers and communicating them with coherence to upper managers. Someone will use it to develop an Agile ChatGPT, then another with a Scrum ChatGPT, and then a third, initially a joke, but later accepted as the preferred one, the Waterfall ChatGPT.
eatmyshorts··on Driving Amazon’s electric delivery vehicle: Rivian EDV [video]
Yep. I've passed on this generation of fully electric vehicles because none of them offer physical buttons to operate the climate control.

Automatic climate controls don't cut it--change directions such that the sun starts beating down on me and I'm going to need to turn up the fans beyond what automated systems would choose. Test driving the Tesla Model S, on two separate occasions while attempting to set the climate controls I almost got into a wreck--it not only is only on the touchscreen, but also buried under something like 5 menus. WTF? Volvo XC-40 and Mustang also have no climate control buttons. In my area, all the other electric cars have a waiting list longer than a year. I want to buy electric, but safety is paramount--driving a car is far and away the most dangerous thing I do on a daily basis and I'd like it to be as safe as possible. I ended up with a Subaru this time.

Hopefully someone will make an electric car with physical buttons for the climate controls.

eatmyshorts··on As last module docks, China completes its space station
"table" is an antonym depending upon your location. For Americans, in the context of a discussion, the verb "table" means to set it aside and stop discussing it. For Brits, it means to bring up a topic and discuss it.
eatmyshorts··on Do we need a better understanding of 'progress'?
I think your data is a little old. The undernourished, defined as fewer than 1800 calories per day, has steadily declined from 2000 until 2019, and then risen very slightly as a result of Covid. There's about 660 million that meet this threshold. Global malnutrition really has gotten significantly better over the past few decades. https://ourworldindata.org/hunger-and-undernourishment
eatmyshorts··on Ask HN: Pros and cons of V8 isolates?
V8, at its core, is single-threaded. I think that's the reason for separate processes for each isolate.
eatmyshorts··on Quick Tip: Enable Touch ID for Sudo (2020)
Is there any way to do this as a 2nd factor, so that both my password and my fingerprint are needed for sudo?
eatmyshorts··on Carbon dioxide now more than 50% higher than pre-industrial levels
It's happening throughout Europe and North America. The United States has had declining per-capita carbon consumption since around 1970. Absolute levels, which include population growth, have been going down since around 2000. We're replacing high-carbon power sources (i.e. coal) with lower carbon power sources (i.e. nat gas) and carbon-based sources with renewable sources, with wind and solar now producing some 13% of the total energy consumption and 20% of domestic energy production, more than double the percentages from 2015.
eatmyshorts··on Minikube quickly sets up a local Kubernetes cluster on macOS, Linux, and Windows
K3D also mimics a multi-node cluster. K0s, K3s, Rancher Desktop, Minikube, and Docker all run (by default) a single-node cluster. This can be useful when learning about Kubernetes and how it would function in a "real" cluster.

K3s and K0s both operate with control plane components not running in containers. Again, when learning how Kubernetes functions, hiding these control plane components can be counterproductive. However, this also means K0s and K3s require fewer resources than the others, giving you more room to run workloads. Additionally, K3s now supports multi-node clusters and multiple options for etcd, including several options that allow for an HA control plane.

Personally, I am a big fan of Rancher Desktop (K3s under the covers), and on my M1 Mac I find Docker to be the most complete and easiest to use. Docker Desktop is for-pay except for small companies and for open-source projects.

eatmyshorts··on Controlling the nuclear fusion plasma in a tokamak with reinforcement learning
Another big one is the default-to-safety nature of fusion vs. fission. With fission, if things go wrong, the nuclear process often speeds up and can run out of control. With fusion, generally when things go wrong temperatures dissipate and the fusion process halts naturally.
eatmyshorts··on ‘Farms are failing’ as fertilizer prices drive up cost of food
No, it's correct. The plains states are so fertile because of hundreds of millions of years of shallow ocean water led to huge amounts of plankton to die and settle. That's also why there's oil in Texas, Oklahoma, and Kansas.
eatmyshorts··on Steve Wozniak announces private space company to clean up space debris in orbit
How much money would SpaceX lose per day in that event? I imagine the thread of a cascading set of collisions becomes more likely after the first one, also. I think SpaceX would be very interested in clearing debris as soon as possible in the event of a collision. Months or single-digit years likely would cost SpaceX many billions.
eatmyshorts··on Steve Wozniak announces private space company to clean up space debris in orbit
I think that will change very quickly when we have a collision in space. I imagine SpaceX, for instance, would be pretty interested in cleaning up space junk if two of their LEO satellites collide.
eatmyshorts··on NSA Kubernetes Hardening Guidance [pdf]
In-tree replacement is coming in v1.22...as in, just a few weeks away. It uses admission controllers, just like OPA/Kyverno et al, hence the current guidance to use one of those.
eatmyshorts··on DeepMind says reinforcement learning is ‘enough’ to reach general AI
I'm curious why you feel their best partner would be Tesla instead of Alphabet's own Waymo?
eatmyshorts··on Ercot nearly at capacity for Texas power grid
I was agreeing with your points....until I got to the bit, "Texas typically imports from neighboring states". Not with power. ERCOT is an isolated grid.
eatmyshorts··on New Relic to open-source Pixie’s eBPF observability platform
You're being too modest. Pixie is a general purpose observability and monitoring tool, with especially strong attributes around APM.
eatmyshorts··on Why is Apple's M1 chip so fast?
The rumors I've read so far is that the next chip will be the M1-X, and will be a 12-core CPU, with 8 "high performance" cores and 4 "efficiency" cores, and will be released in a 16" MBP. The current M1, by contrast, has an 8-core CPU (4 HP cores and 4 efficiency cores).
eatmyshorts··on The Untimely Demise of Workstations
Oh, I agree. But at the time, I thought BeOS had the edge from a technical standpoint. With Gasse, I doubt we would have seen the iPhone, iPad, and Apple Watch. Hindsight is 20/20.
eatmyshorts··on Introducing the next generation of Mac
That's an Intel MBP, not an M1 MBP.
eatmyshorts··on Eric Schmidt has applied to become a citizen of Cyprus
You are taxed on income you make abroad, even if you never set foot in the country. I'm not talking about capital gains. I'm talking about income. Yes, up to a certain amount, you can deduct dollar-for-dollar taxes paid in the foreign country, but you are still taxed on that income. It's the only country in the world that does this. Because of this, among other bits, I do not think it is reasonable.
eatmyshorts··on Eric Schmidt has applied to become a citizen of Cyprus
He'll have to renounce his US citizenship, which means he would never again be able to set foot in the US (even for "connecting flights").
