Yes, it feels like a certain project that was foisted upon me.
Fixed price SOW with a vendor to build a thing my firm didn't have domain knowledge in.

Paid them to design a thing, then paid them to implement the design, as well as project manage themselves. SOW lacked meaningful acceptance criteria / objective tests.

Of course, it was non-stop debacle of new things being discovered during implementation. Weekly status calls just turned into recrimination sessions with fingers pointed in all directions as to who is responsible for the time/cost.

You can't rent knowledge.
How do they take those CPU pictures? Are those "delidded"? False color xrays?
I feel a lot of similar recommendations on HN are to ask the left hand to slap the right or even slap the mouth that feeds them.

The point is, they don't care about us. We are just clogs on a machines and we are one type of resources just like coal and iron.

The only way to struck fear is by some collective methods but then everyone got spooked by "Socialism", so the whole thing becomes a perfect loop for the aristocratics.
I like this one!

I was curious what the margin of error for this was (I'm conjecturing the sum of widths of the fingers touching the stick), so I tried this out, but with a pencil instead of a stick.

I was consistently getting just off-center, so I was thinking maybe the 'surprise' wasn't consistent, until I realized the end of the pencil (metal + eraser) is probably denser than the wood and shifts the center of mass to exactly where my fingers ended up. :)

sorry, you lost me at: "Reason 1: You Reward The Right People The Right Amount"

if that were true, i too would say that Performance Reviews matter. i'm 45 and it's literally never been true at any place i've worked.

"Without them, you’re letting managers just make things up." sadly with them you are also letting managers just make things up.

we pay so much attention to the hiring process, but i think Performance Reviews need a shake up. i've consistently seen the wrong people rewarded. you want to talk about people only hiring people who look and act like them? how about people only promoting people who look and act like them?
It is though, it's just a matter of perspective. The recursive method would look like this:

str1 = ...
str2 = ...
def lcs(i, j):
if i <= 0 or j <= 0:
return 0
res = max(score(i-1, j), score(i, j-1))
if (str1[i] == str2[j]):
res = max(res, score(i-1, j-1) + 1)
return res

Now if you memoize this and make it iterative, you end up with your DP solution.
Extracting and Depositing Bits
You can build containers with nix, but they’re completely different. One is an operating system built around a package manager and the other is a containerization tool.

More appropriate comparisons would be:
- NixOS and Ubuntu
- nix and apt/homebrew

the "check back in a month" soon. I have versions of it that work but I just haven't been satisfied with. also, the major underlying dependency (Marvin) is going through a large refactor for v2. once that stabilizes a bit, I'm going to upgrade to it and that might simplify the code I need a lot

Amazon's logistical side is still solid. Pretty much the only reason why I still give them any business... but independent stores are catching up on that front.
These attack vectors have been around since 2010, I built a zero click Bluetooth jailbreak for iOS.

We put it into a directed yagi antenna and made a “gun” that could shoot folks with a jailbreak. Fun demo, but it made the world less safe so we disclosed it to Apple.
Been running solo bootstrapped SAAS for 8+ years already and have seen moderate success (low 7 figures in ARR). Nothing worth gloating but I can build a few things and sell. I have employees but no true partner/co-founder who lives and breathe this stuff with me.

Have some fresh ideas for which I would love to team up. Technical/non-technical doesn't matter. You either build shit or are awesome at talking to customers. I do both as well. If this is you, hit me up. Will start with some side projects together to test compatibility first.

I am in East Coast (Southern NJ). 20 mins from Philadelphia and 1.5 hours from NYC, 3-4 hours from DC. For co-founders, I personally believe that we need to work together in person at least in the beginning. So that's a hard requirement for me.

Note: Experience with YC Founder matching has been terrible at least for me so far.
I have had a great experience using the Nix package manager on other Linux distros. It's super easy to try out software with `nix-shell -p somepackage`. (It's a little rockier on macOS.)

Another neat trick is reproducible shell scripts that use Nix to declare their dependencies in a sort of extended shebang line.
Playing around a bit, I think the margin of error is probably the average of the sum of widths (so the width of a finger, if they're equal).
AMD has almost completely taken over the console market. The PS2 was a MIPS system and the PS3/Xbox360 were PowerPC, but, for the last ten years, Sony and Microsoft have been all AMD. Intel has been out of the game since the original XBox, and nvidia only has the switch to its name. The Steam Deck-style handhelds (like the ROG Ally and the Lenovo Legion Go) are AMD systems.

It’s kind of interesting how they have this hold on gaming outside of conventional PCs, but can’t seem to compete with nvidia on just that one market.
That’s amazing. Thanks for letting us know how it should be done. Hope US Universities are taking notes.

because a plane falling out of the air has much larger potential for distruction than car running into another.

Because its easier to regulate 30,000 planes owned by a few dozen airlines made by a handful of manufacturers, than it is to regulate over a billion cars owned and maintainted by hundreds of millions of drivers and made by hudreds of manufacturers.
> Given that I understand all the bad things that a business can do, how do I structure a relationship with a service provider such that I get the benefit of their service, and avoid the bad stuff? What tools can I use to ensure our interests remain aligned?

Has any business really succeeded in keeping business information confidential while outsourcing operation of that information? It seems like at a minimum you'd need a PCI-DSS/HIPAA-style audit regime, which I haven't seen the likes of MS granting access for (why would they?); even then those schemes aren't great at protecting confidentiality. Core business trade secrets get leaked all the time; the idea that a company would manage to protect stuff that's proprietary but peripheral, like how they use their workflow tools, seems like wishful thinking.
Correct this is the best path forward. Night time is typically when there is less traffic and we should be able to at least utilize that for autonomous transportation between distribution centers. Then slowing keep upping the advancement as roads are repaired, replaced, etc. If you build a smart road for lets say just trucking, now you can map out the best places for distribution centers, similar to what UPS, Fedex figured out for air transportation and packages.

Its a bit ridiculous that in 2024 we have all these apps that tell you about accidents and obstructions but none that actually help re-direct traffic in a meaningful way. You have to hedge your bets on any "suggested" better route.

With smart roads department of transportation could get real analyze on crowded intersections, best place for future on/off ramps, access roads, etc. Traffic congestion and planning is usually an after thought when housing developments go up and then its a catch-up game.
Full agreeance.

I grew up poor, had stints of homelessness, and all my friends/relatives came from the same background.

Learned helplessness is one of, if not the biggest, issues facing socially disadvantaged people. Money, counselling, temporary housing - all of this is moot and useless if the person retains a poor mindset.

Conversely, if there's a positive mindset, then they are most likely going to seek out those opportunities and use them to their advantage.
> That’s called going to college.

This is legacy thinking. There’s no reason that in the Internet age this should be necessary anymore.

The current college system is simply a tradition from a bygone era that hasn’t really adapted to the 21st century yet.

I don’t accept the characterization of being thorough as harping, or that anyone would need to be unrelaxed for that. Is that ironic with me being told to assume good faith?
It’s one of those things that cloud storage helps with.

Because it was on prem, the chargeback model was associated with the business unit and not super granular. It got lumped in with another business function because it should be a trivial workload.

I found it when I was doing estimates for a new platform and the app’s growth numbers didn’t add up! Even at $240k, it wasn’t an obvious outlier.
The blog has RSS.
If I remember right, I think Valve has implied that the steam deck arose out of prototypes for a wireless VR headset, so it could be possible there was some early collaboration to that effect, and Valve ended up taking a different path once they realized what the steam deck could be?
It is somewhat depressing that when you accidentally make a comment that attracts a lot of downvotes, you can't even delete it and have to watch them rolling.
You want KFC for dinner.

Down the street are 2 different KFCs.

One uses oil that sometimes, a very small percentage of the time, will instantly kill you. The other does not. They arrived at using the riskier oil because it saves them 5c a day and it makes the books look better.

Are you really asking why anyone would even bother differentiating these two because the drive to the KFC carries more risk?

Why would you as a consumer want to fly on something with an ever worsening safety record?

Why would you as an airline want the bad press, loss of revenue, and loss of reputation associated with a safety incident?
Mushrooms have had a profound positive impact on my life so I'm drawn read anything in the orbit of psychedelics, but I'm even more interested after this interview! I pre-ordered a copy.

It was cool to see your mention of Ginsberg and the Beats, my wife and I just stopped through City Lights and the small, but pretty neat, Beat museum that's nearby.

Anyway, congrats on the book, I look forward to reading it!
Ships in drydock are not full of goods.
Driver fatigue is taken way more seriously than it used to be and measures and laws have been put in place to minimize it by forcing maximum driving and minimum resting periods.

So, ignoring the fact that society doesn't just get together every year and decide to let people die, I'd say it's absolute cynical hyperbole to say society is "letting truckers die".
He did saddle Twitter with an unsustainable level of debt as well.
wonder how much of this could be solved with a $10000 sensor post every 200m of road?

48k miles in the interstate = 80k km, 400k posts, 4 billion dollars (and you can start regionally)

could also run semi-autonomous convoys where a robot truck follows a human truck, extending sensor range
Outside of veblen goods, aren't most consumer choices driven by price?

I have never flown top tier air travel, but even the best experience is somewhere on the scale of cattle-car-in-the-sky. It is a necessary evil to get me to somewhere in a way that is faster than driving. Paying a premium has rapidly diminishing returns when you are stuck in a shared space with the public.
its a real birding term, i have heard older birders say it

I like the idea of nixos. Having one file responsible for all packages installed on the system is way better than what traditional distro use. I just don't like the quality of the packages. It would be nice if someone could do something like a os wide packages.json but for a mature packages repository like Debian.
Chatgpt doesn't have taste buds; it isn't a reliable authority on this or anything else. Couscous, like any other pasta, has little flavor and serves as a starchy vehicle for whatever flavors you choose. There are sweet preparations, there are savory preparations.

To not diversify a concentrated wealth of 8+ figures takes some serious diamond hands.
Better composability and abstraction, see for example how you can configure a process in https://devenv.sh/services/ that has first-class support for development environments using Nix.

No need to use containers too, which bring cognitive/workflow overhead.
I don't understand why you would use memoization for fibonacci ever and hence its relevance for dynamic programming. It can be solved with a tail recursive function with three input parameters. Solution left to the reader as an exercise.
yes, as it should have.

first of all, there's no point in having all kinds of low-added-value industry in high-income places as long as there are millions of people willing and able to do it all in the same place close to a port.

second, US industry suffers from two major problems. protective tariffs keeping productivity low, and the 'exorbitant privilege' of the USD being reserve currency of the world, which counterintuitively hurts export of every non-finance sector
Ask HN: How do you handle high cardinality configuration that changes often?
I define high cardinality configuration as configuration values that depend on multiple input variables with (relatively) high cardinality, while the output is usually single valued / low cardinality.

For example consider a company that offers a service and charges a price for it. The target configuration value here is the price that needs to be shown to the customer. The company operates in all 50 states, but charges a different price in some states due to regulations. They also have other variables that impact pricing such as membership tiers, age of customer, etc. They might also want to experiment with a different price for a subset of customers in a particular state. Here the input variables are high cardinality (50 states × 5 membership tiers × 3 age groups), but the target value is just price, which potentially has 5 different values.

I would imagine that the above scenario would be handled through a mix of configuration values for the general case + special casing if-else logic in code for corner cases that cannot be easily represented in configuration.

The main concern I have is splitting of the actual business logic between the configuration + special casing code. I would personally prefer if I just had a magic dictionary that would give me the price I need to show a customer given their state, membership tier and age, and the map would contain all the business logic.

I imagine one argument would be that "the code + configuration is the magic map you're looking for". But I've seen this pattern blow up in many different ways in my admittedly limited 5 years of experience as a backend software engineer. For example, some external service handles the logic to override the price based on a particular variable, which blows up things in an unpredictable way when changes are made in that service. My example is not perfect because it reeks of bad abstraction, but I just wanted to make the point that having multi variate rules is hard to write and even harder to maintain.

One more way I've seen things become unmanageable is when the number of special case if else statements blows up such that no one understands what will actually happen if you add a new variable to the mix, or add a new condition to an existing variable. This again is not a perfect example because you should ideally have tests to have confidence to make changes, but the point remains.

I ask this question because I was considering building a configuration store that can store multi variate hierarchical / range based configuration, so that all logic lives inside the configuration, and can be changed easily and frequently. Not sure if something like this already exists. Please let me know if it already does! Would love to use it instead of maintaining classes full of if-else statements.
If you burn gasoline in an ICE car only about 30% of the energy of that gasoline ends up actually going to propelling your vehicle. The rest is mostly lost as waste heat.

Burn it in a combined cycle power plant to convert it to electricity and there are still substantial loses to waste heat but much less than when burning it an ICE car. There will be some smaller losses in the power grid and charging infrastructure to get that electricity into your battery, and some small losses in your EV's electric powertrain, but in the end around 40% of the energy of the fuel ends up going toward propelling your vehicle.
Doesn't make sense. Switching the road to steel increases cost when the road is not in use because you're building a single-use roadway. Predominant costs here are land acquisition costs. If you can't split land use among multiple users, you're hosed.

Just think about it. You're starting a company and the first thing you need to do is spend a few billion dollars before you move your first ton? Doomed company.

This is the classic problem with rail: you need to plan the route so you have sufficient participants willing to fund development, you need to acquire land (which you can't safely do piecemeal because the guy down the line will extort you).
Why not tunnels that don't disrupt and takeover surface environment preventing nature or other infrastructure - and not impacted by weather?

They’re already buying an Airbus branded Bombardier with an Airbus markup so why not?
Jeez, thanks for the warning!

But, of course, the question is whether anyone will actually maintain the apps.
I just love how we can have a critical study about a failure that could have possibly led to the death of dozens if not 100+ people, a failure in something as routine and critical as flying in an airplane, and the article is behind a paywall.

We're getting very close to the point where the combination of the competency crisis and the greed crisis are going to start causing more people to think twice about doing things that were once common, like flying commercial.

Personally, I cancelled my flight later this month and am going to start getting in the habit of doing long road trips again.

Just-as-if-not-more dangerous? Maybe, but at least I have a higher chance of my fate being in my own hands (swerving out of the way of an oncoming truck vs being sucked out from a fuselage plug failing).

More inconvenient? Yep, don't care.

More expensive? Maybe, don't care.
Thanks for the comment. I will be chronicling my progress on the blog!
Author of the package here. That's pretty much what this package does just with optimization around what context gets sent to the LLM about the database:

https://github.com/vanna-ai/vanna/blob/main/src/vanna/base/b...

And then of course once you have the SQL, you can put it in an interface where you the SQL can be run automatically and then get a chart etc.
NixOS is also a declarative build of the entire machine as opposed to just a container also, so it's totally normal to have a NixOS build with multimedia apps, games, etc.
To me, Docker is for building an entire environment for a single app to run in, whereas NixOS is for building an environment that runs multiple apps. Like a microservice vs a desktop machine.
To clarify, this secret stealing is not an issue with GitHub-hosted runners, correct?
Pump it from where though? It would be easy to pump and reuse the water that already goes through the locks, except that it gets mixed with salt water, so putting it back in the lake would quickly contaminate it.
Because it's a good example to teach dynamic programming?
8 years ago i made a video series about making a website with a REST API using Pharo. i still have the videos on a backup somewhere, but the site where it was posted got lost. however, it turns out that archive.org luckily has a copy including the videos:

This is correct. After trying out Smalltalk, I realised that Emacs has very much the same design: a minimal interpreted language which is used to implement a large program, where you can inspect and modify the program at any time. The major difference is that Emacs isn’t image-based.
Perhaps. But it is hard to argue that despite all the open content available the current system is remarkably effective at keeping the higher education credential gate firmly closed for the very vast majority of humanity.
That's true of every online marketplace unless there's no 3rd party sellers.
TL;DR - it probably cost the Post Office several houndred thousand dollars in internal time to fix this, rather than $500M.
Which package did you have issues with?
> Ships are made to be drydocked.

Not while fully loaded with thousands of containers.
Yeah I’ve wondered this too I think the safest path to driverless if we insist on deploying that technology is deployment into road infrastructure

Driverless trains put about half the system logic outside the vehicles and those things operate mostly incident free
ah! then it is good to be needed :)
I wrote an AH script. It would scan every auction, buy under-priced items, and relist. If someone undercut me, it could cancel and relist just below them. I basically had unlimited gold.
Thinking about modern chips in terms of units and inventory isn't the best way to do it. Cutting-edge logic isn't quite priced like software, but it's close enough: the first unit costs $10m in R&D and NRE (Non-Recurring Expenses, like mask sets and test tooling) and then the second unit costs $1 or so.

My guess is that Magic Leap, a company infamous for spending profligately, paid for the NRE on this design, and then didn't buy very many of them or pay for exclusivity on it (or let any exclusivity go). AMD is notorious for shopping around designs they've already got ready to ship (probably related to sibling comment's observations about the console graphics market), and Valve runs lean despite not having to, and so this story adds up quite nicely. There may or may not have been some inventory lying around, but the NRE is usually the real story on these things. (It's also possible that the custom Magic Leap sections of this chip have terrible yield -- actually that wouldn't surprise me at all -- and so these were great candidates for die harvest. Which of course is also the sort of thing AMD loves to sell.)
