dx034··on NASA overspent $15M on Oracle software bc it was afraid an audit could cost more
I second the part about US startups. Compared to what Oracle delivers (really solid database clusters with everything enterprise customers need built in), their cost is actually not that high compared to other enterprise software. Especially SAAS that are only solve a narrow problem and can cost a lot.

To be clear, I'm all in favor to switch to Postgres for most workloads, but rather for new systems as migration old ones is either impossible or much more expensive than paying licensing fees.

dx034··on Founder who sold to JP Morgan for $175M allegedly fabricated 4M accounts
I like that the engineer refused to do the job. The founder managed to get someone else to do it, but refreshing to see engineers stand up to bad business practices.
dx034··on CTEs as lookup tables
With CTEs, the optimizer won't execute the queries but create one optimized version. If you materialize them, execution times can be many magnitudes higher in cases you only end up using small parts of the queries.
dx034··on Do heat pumps work in cold climates?
F or C?
dx034··on Ask HN: What's your favorite illustration in computer science?
Honest question for those who have worked at several software companies: What works best? The chart displayed with Google with lots of connections but also a lot of complexity, or the "traditional" Amazon chart?
dx034··on FAA NOTAM System Outage
Looks like they published some kind of a "master NOTAM" now with all important information to restart as soon as possible.

dx034··on FAA NOTAM System Outage
More modern systems are also down once in a while. With aviation it's just more visible because one system can affect a lot of people.

I'm not sure when ATC systems (which I would count NOTAM to be one of) have last failed, I always had the feeling they're very stable. It's usually airlines that struggle with their applications.

dx034··on FAA NOTAM System Outage
I never doubted that. The question is if they could've worked without a ground stop by having ATC give them all info.
dx034··on FAA NOTAM System Outage
The question is, how will ATC know? I'm not that familiar with their systems, but maybe they rely on them to get critical information?
dx034··on FAA NOTAM System Outage
There's a ground stop for all flights now.

GROUND STOP ALL FLIGHTS / ALL DESTINATIONS EXCLUDES MILITARY AC AND MEDEVAC FLIGHTS DESTINATION AIRPORT; ALL FACILITIES INCLUDED: ALL GROUND STOP PERIOD: UNTIL 1430Z REASON: EQUIPMENT OUTAGE REMARKS: US NOTAMS SYSTEM DOWN

dx034··on NanoGPT
That's still including margins of cloud vendors. OpenAI had Microsoft providing resources which could do that at much lower cost. It still won't be cheap but you'll be way below $5m if you buy hardware yourself, given that you're able to utilize it long enough. Especially if you set it up in a region with low electricity prices, latency doesn't matter anyway.
dx034··on Mercedes is the first automaker to offer Level 3 self-driving in the US
The thing is, most Mercedes employees are over forty. So while news outlets might exaggerate, Mercedes doesn't really. They tend to only publish products when they're ready.
dx034··on Mercedes is the first automaker to offer Level 3 self-driving in the US
And Mercedes has been pumping huge amounts of money into it for at least a decade. They're just much more conservative than typical SV companies so they only publicly announce products when they're ready.
dx034··on Mercedes is the first automaker to offer Level 3 self-driving in the US
It's important to note that healthcare is much cheaper in Germany than in the US. In addition to that, compensation for injuries also tends to be much lower. That massively affects the costs of accidents.
dx034··on Mercedes is the first automaker to offer Level 3 self-driving in the US
It's legally possible but no car uses it. Mercedes might be the first but they're still limiting at lower speeds.
dx034··on Old man yells at cloud
And Steam is really a great piece of software when it comes to utilizing your connection. They can saturate even high capacity connections much better than any other software I know and you can play basically immediately after the download has finished.
dx034··on Old man yells at cloud
Excel brings out new features all the time while keeping 100% backwards compatability. The difference in features between old and new versions is staggering. They knew parts of their usage would get replaced by other software if they don't innovate, and so they did.

Don't get me wrong, I'm not a fan to use Excel for all the use cases it's being used for, but it's probably by far the most versatile software out there and powers more businesses than any other software.

EDIT: And if you need an example for a new feature that users wanted, I heard a lot of people being really happy about the introduction of XLOOKUP, introduced very recently.

dx034··on Fuel from the sky: Cheap hydrocarbons from CO2 direct air capture and sunlight
Even with cheap Solar, many regions will still need Gas or similar fuel for electricity and heat generation in winter. If that gas can be transported and used with existing infrastructure, that'd be a huge bonus. So there's definitely a market, the question just is how to be cheaper than natural gas.
dx034··on Software horror show: SAP Concur
Which shows how complex enterprise use cases can be and how valuable good SAP consultants are. With all its faults, for many large companies it's still much better and cheaper to have all processes on SAP than using dozens or hundreds of specialized (often self developed) applications. At least with SAP you always find someone who will help you, with your 20-year old in-house developed software, no one will want to touch that code again.
dx034··on Stripe is about to refund €147k worth of payments to my all of my customers
They said it's about kitchen/household items, so that doesn't seem to fit. Also I'd be surprised if that store got sales that high in a few weeks.
dx034··on Stripe is about to refund €147k worth of payments to my all of my customers
Of course they do. Their APIs are just way worse and documentation can be really bad as you have to connect to decades-old systems. But once it's up and running they will honor their agreement.
dx034··on Slack's private GitHub code repositories stolen over holidays
We run it in our VPN with SSO for authentication. You'd need a company device, user credentials and a location that's whitelisted to access.

For smaller companies something like Cloudflare Teams and/or Tailscale would probably also add a good layer of extra security. I guess it's important to have some device whitelisting in addition to credentails, so that stolen credentials alone are not enough to access code or chat.

dx034··on AMD Announces 7950X3D, 7900X3D Upto 128MB L3 Cache
Not only not fitting in RAM but also initial loads. Loading times could be reduced even further.
dx034··on Slack's private GitHub code repositories stolen over holidays
Self-hosted Mattermost and Gitlab can be done reliably at very low cost, had better uptime than their cloud services for us and would've likely prevented leaks like these. At least you can add some layers of security for self-hosted services so that stolen tokens aren't enough to steal code or messages.
dx034··on Microsoft is preparing to add ChatGPT to Bing
As a blogger I don't really have incentives providing content if no one will read it. Sure, places like HN can still promote those, but that's no comparison to Google.

Even without monetization, the size of the audience is a big incentive for many to create content. And monetization isn't bad, it allows some content creators to spend more time and resources on their content.

dx034··on Microsoft is preparing to add ChatGPT to Bing
What I don't really understand is why there are usually so many discussions on how Google, Microsoft & Co are killing the web, but here the majority seems to be in favor.

Once search engines work like ChatGPT, the incentive to click through to the source will be extremely low. That destroys any incentive to create content and will kill many blogs and sites with high quality content. The likes of Reddit and Twitter can survive this, most blogs have no chance to exist if ChatGPT uses their content but users don't click through.

dx034··on Posters of the IPv4 and IPv6 internet as of Jan 1, 2023
Does anyone have a good resource to really get ipv6? I have an intuitive understanding of ipv4 but still struggle to understand ipv6 in a way that would make me feel comfortable switching over. So far, all docs I read made it look vastly more complicated than ipv4.
dx034··on 72-year-old Congressman pursues a Master's in AI
It's fine to stop learning at some point. But that's for when you're retired. As long as you still opt to work (and a congressman definitely had the option to retire), you also have to keep up with the world.
dx034··on Ask HN: How did Microsoft email services became the primary source for spam?
> Mailchimp, Constant Contact and their ilk are truly a scourge upon our inboxes. You know they're truly terrible companies because if they ever provided a global opt-out of all their email lists from all their clients, they'd go out of business.

I don't think the majority of internet users supports that view. I know many people who are subscribed to countless newsletters but don't want to unsubscribe, even if it's very easy. They like receiving offers from companies they bought from years ago. That's also why newsletters work so well for many companies.

So while many people here might dislike any email they didn't ask for, that's not necessarily the view of internet users as a whole.

dx034··on Even after $100B, self-driving cars are going nowhere
Having kids makes car sharing very unattractive. Finding car sharing with enough (and high quality) car seats can be quite challenging. And as much as I like public transport, with kids using the car is often much faster.
