CBLTon Is a movie prop the ultimate laptop bag?

I've had my car burgled twice for them to only steal a backpack with nothing in it. I'm pretty sure the assumption is that backpacks have laptops.

CBLTon Ultrasonic Chef's Knife

I use a knock-off of the edgepro I got for $30 online, with a nice set of compatible whetstones that click into the assembly that were $20 online. I did what everyone else does and hotglued some magnets underneath the piece you hold the knife on.

I tried a compatible strop that clicks in but it's not worth it imo; just use a normal strop.

CBLTon AMD Open Source Driver for Vulkan project is discontinued

https://www.phoronix.com/news/AMDVLK-Discontinued

> This is a good but long overdue decision by AMD. RADV has long been more popular with gamers/enthusiasts on Linux than their own official driver. Thanks to Valve, Google, Red Hat, and others, RADV has evolved very nicely.

CBLTon Show HN: Pooshit – Sync local code to remote Docker containers

Line 1 of the readme has a poop emoji

CBLTon React is winning by default and slowing innovation

Vercel is anything but simple. Easy? Sure.

CBLTon Health care costs are soaring. Blame insurers, drug companies and your employer

I live in the US. A family member close to me is unable to make appointments any closer than 6 months to receive lifesaving care. This is despite getting the most premium insurance they could find.

They (easily) found someone who will see them out of pocket. It's not a supply issue in this country, it's an incentives issue.

CBLTon Homeowners insurance is pricing people out in disaster-prone cities

It's not just an incentive to home buyers, it's a shift-left that will make it all the way to developers. Homes will only be built that are affordably insurable, whether that means better location or more disaster-proof construction.

CBLTon Running our Docker registry on-prem with Harbor

I mentioned two things that were broken:

1. Doesn't work with ExternalSecretsOperator and ArgoCD, which I happen to use. This is because the author of the Harbor chart decided not to use k8s concepts like secretRef in a podTemplate. Instead, at Helm template time, it looks up the secret data and writes it into another secret, which is then included as a envFrom. This interacts poorly with ExternalSecretsOperator in general, because it breaks the lifecycle control that ESO has. It's completely broken with ArgoCD because ArgoCD disables secret lookups by charts for pretty valid security concerns. No other chart I've come across does secret lookups during helm template time. Even the helm docs tell you it's not correct.

2. Harbor requires redis, but the Helm chart doesn't correctly pipe in the connection configuration. Redis can't be behind TLS, or the chart won't work.

CBLTon Running our Docker registry on-prem with Harbor

I also run Harbor. I use the official Helm chart; it's a little jank, doesn't support a couple of things we want. It only works with one of ArgoCD/ExternalSecretsOperator, and it doesn't support Redis TLS.

Contrary to the author of this post, we just run one (the "source of truth") and use caching proxies in other regions. Works fine for us.

CBLTon Does MHz Still Matter?

I'm in disbelief that the software you run is completely insensitive to IPC and instruction latency. Without those number, clock speed is meaningless.

CBLTon Spotting base64 encoded JSON, certificates, and private keys

I don't always store my Kubernetes Secrets in files, but when I do, I prefer stringData.

CBLTon Live coding interviews measure stress, not coding skills

> You must know by heart the most common algorithms out there and design solutions that might involve two or three of them to solve a problem in 30 minutes.

You're not going to pass every interview. Some of them are truly outlandish, and require all of the above.

What you need is the technical knowledge to translate requirements into a loose pattern like "This looks like a search problem", then have the charisma (or more accurately, practice) to walk the interviewer through how each search algorithm you know could apply there. Then of course be able to actually write some code.

I've passed interviews where I had never heard of the datastructure they wanted me to solve it with; I just walked them through the tradeoffs of every data structure that I knew applied to it instead.

CBLTon Intel CEO Letter to Employees

They make that claim because what CEOs write down could easily be written by a Markov Model, nevermind an LLM. If that was the primary value a CEO brought to the company they'd be right.

The most important thing a CEO brings is relationships. LLMs can't do that (yet).

Post script: there's still a chance that LLMs replace CEOs due to LLMs being easier for the board to influence/control.

CBLTon Scarcity, Inventory, and Inequity: A Deep Dive into Airline Fare Buckets

I'm not the best person to answer, but it's really any price<->X tradeoff, whether that's being able to choose at the last minute, going to your preferred airport in the destination city, or even those other bullshit upcharges airlines have.

CBLTon Scarcity, Inventory, and Inequity: A Deep Dive into Airline Fare Buckets

I worked for an airline fare pricing startup. The key to getting a lower fare is to not be flying for business.

Since airlines can't outright ask you if you're flying business, they'll instead offer tradeoffs that a business flier won't make. So plan in advance, but be flexible in trading off day-of-week or time-of-day.

CBLTon Broadcom to discontinue free Bitnami Helm charts

Helm gives you more than enough rope to hang yourself with. At $dayjob we barely use 3rd party helm charts, and when we do we eventually run into problems with clever code.

We do package our own helm charts, not in the least because we sign contracts with our customers that we will help them run the software we're selling them. So we use package docker and helm artifacts that we sell in addition to running locally.

So we write some charts that don't use most helm features. The one useful thing about Helm that I don't want to live without is the packaging story. We seem to be the only people in the ecosystem that "burn in" the Docker image sha into the Helm chart we package, and set our v1.2.3 version only on the chart. This means we don't have to consider a version matrix between our config and application. Instead we just change the code and config in the same git sha and it just works.

CBLTon Everything You Need to Know About Grok 4

A bit too much praise for a model that's barely ahead of the competition in a subset of benchmarks...

CBLTon Show HN: A local secrets manager with easy backup

> You can rsync a JSON file just as you can rsync a SQLite file....

`sqlite-rsync` does a deep comparison and only transmits new rows, without deleting other data. `rsync` on a json file just replaces the file.

CBLTon Show HN: A local secrets manager with easy backup

I use pass[0] which uses a flat directory structure and git. It works great! At $dayjob we have json lockfiles committed to git and merges get pretty gnarly. Not as big of a fan of just dropping it all in json. The toml lockfiles are a bit better in git.

CBLTon Show HN: A local secrets manager with easy backup

Skimmed the readme, seems like it's not AEAD? I don't see any reason to use a tool that's not AEAD.

Also, while I get the appeal of just storing it all in a giant JSON, I don't really feel that's the final word in simple storage formats. I'd personally just use SQLite, or some other format I could rsync.

CBLTon Calculating the Fibonacci numbers on GPU

Writing C code that performs this fast doubling algorithm for Fibonacci numbers was actually quite fun. Highly recommend it.

In my experience where I didn't modulo the numbers, the compute time was dominated by the last couple of multiplications with Megabyte-sized integers.

CBLTon Kea 3.0, our first LTS version

The submitted link might be better changed to the actual release notes: https://gitlab.isc.org/isc-projects/kea/-/wikis/Release-Note... which start with this information.

CBLTon Immediate PB2-E627K amino acid substitution after single infection (...)

I thought so too, but later on in the paper they mention that they performed necropsy on the mice that survived.

> samples from surviving mice on day 12 were also obtained through necropsy to measure viral titers.

CBLTon Immediate PB2-E627K amino acid substitution after single infection (...)

The paper is interesting, but it doesn't seem to be supporting your title? I'm just past the part where they showed 100% infection rate in mice.

CBLTon The time bomb in the tax code that's fueling mass tech layoffs

You're right, the law text doesn't specifically call out the Windows operating system or the Linux operating system. The example you gave of Open Source Windows drivers is valid.

The Grandparent's point about that "it double-dings open source developers" is still correct and poignant even with this clarification.
