pragmatic··on Circular Financing: Does Nvidia's $110B Bet Echo the Telecom Bubble?
Everything in that data center is depreciating as soon as they turn on the power.

AC, ups, generators not to mention the severs.

That's the thing with fiber it was still useful. The cards at either end are easy to add, waaaayyy cheaper and higher perf (they're were no cards on end of dark lines) 15 years later.

pragmatic··on Circular Financing: Does Nvidia's $110B Bet Echo the Telecom Bubble?
In 2005 telecom was a cash cow because of long distance charges and if your mechanical phone switch was paid off you were printing money (regulations guaranteed revenue)

This didn't last that much longer and many places were trying to diversify into managed services (data dog for companues on Orem network and server equipment,etc) which they call "unregulated" revenue.

Add written an things business, irrational exuberance can kill you.

pragmatic··on Circular Financing: Does Nvidia's $110B Bet Echo the Telecom Bubble?
At a "telecom of telecom" we (they) were still lighting up dark fiber 15 years later (2015) when mobile data for cell carriers finally created enough demand. Hard to fathom the amount of overbuild.

The only difference is fiber optic lines remained useful the whole time. Will these cards have the same longevity?

(I have no idea just sharing anecdata)

Can I ask why define these in json?

Devs aren't going to like that over c# and data engineers/biz folks want more of a graphical tool.

Who is your audience for this?

It does not.
pragmatic··on The AI vibe shift is upon us
This is why EXAMPLES in getting started pages are so important.

LLMs are making up for the lack of this.

It’s the Backus-Naur approach vs the Human approach.

Humans learn by example. IMHO this is why math education (and most software documentations) fails so hard - starting with axioms instead of examples.

pragmatic··on 450× Faster Joins with Index Condition Pushdown
What are “db guys” in this context?

There are two distinct job functions.

1) dba - maintain OS, db software/hardware - DBs are complex beasts you want experts setting up hardware or deploying into the clown in a smarter way (virtual machines in the clown will cost you a fortune and your sanity) 2) database developers- specialists in writing sql.

The two functions work together but are distinct.

Nowadays due to private equity and Stanford MBAs we have junior engineers doing all plus “dev ops”.

It’s an absolute circus.

IMO, this is why we end up with ask these crazy DB startups - routing around the damage.

RDMS in modern hardware are insanely fast and powerful.

pragmatic··on 450× Faster Joins with Index Condition Pushdown
95% it’s a missing/improper index but the insane workarounds “engineers” put in place actively work against the database.

Does your hotpath query have a covering index? Is it seek-able. Are you predicates SARG-able.

Seriously biggest bang for your buck is to understand SARG-ability and understand indexes in your database really well.

A fellow data swamp enjoyer.

Just dump it in Hadoop became an anti-pattern and everyone yearned for databases and clean data and not dealing with internal IT and the cluster “admins”.

pragmatic··on C# vs. Java int: Primitive type semantics, runtime behavior and tribal knowledge
Wow very indepth.

This used to be (and still is in some circles) a hot topic.

.net had the benefit of coning second and fixed a lot of java's design issues. It really use a better java.

Of course in the days of JavaScript desktop apps and python, people just don't need to pay attention to perf as much for better or worse.

pragmatic··on Good system design
Yes, and then you get the job there and regret it bc they’ll have either have an over engineered Rube Goldberg contraption or they have system envy bc they’ve read about this architecture in blogs and THINK they need K8s and they still fix all their problems.

pragmatic··on From Async/Await to Virtual Threads
But it's actually useful for scalability.

All modern IO is async. The fact that you get this easy to use API to make an app more scalable is a ridiculously good deal.

Now, if you don't really need that, then it just looks like pointless extra work.

pragmatic··on The Most Powerful Server Embiggens a Bit with Power11
They came with avcertain number of power cores, say 8 but you could start by only licensing 4 and then grow into them. Don't remember the exact specs on this but they were crazy powerful 20 years ago.
pragmatic··on The Most Powerful Server Embiggens a Bit with Power11
AIX on big iron.

Used for ex nightly batch processing at banks. Lots of horse power for your on prem needs. Moving this kind of horse power to the cloud would be insanely expensive and complex for the mid size banks relying on these systems.

They shipped these massive boxes out and connected them to massive SANs. You could license the processors later if your workload grew.

I spent a year as consultant to big customers building SOA, websites, SSO for whatever they needed. ATM networks with low latency etc.

People have such widely varying experiences and I’m wondering why.
