retcore··on Why Craigslist still looks the same after 25 years
What absolutely confounds my comprehension of marketplace sites and any online business driven by user directed discovery, is the unbroken and never deviated from practice in every industry and field of making the method and techniques used for search as unique inviolable individual apotheoses of a imaginary USP.

why on earth doesn't occur to anyone that heterogeneous search methods producing a range of results with a identifiable classifiable process or at least perceptual sensibility that users can get some understanding of, might provide not only consumer choice but profit?

The only thing that I can imagine to be happening is the overriding objectives must be econometric optimization and blow every other consideration. Or maybe it's possible with the adherent mantra of "internet speed" development that without constant investment in maintenance "development" nothing will work if left alone while bringing in alternative abilities.

retcore··on Debugging the Postgres query planner (2018)
Hi,

However do you make it that I have claimed that a Oracle license would make your team redundant?

I certainly didn't suggest anything like that.

But please forgive me for being reflexive, has your response accidentally been more revealing than intended about duplicating technologies that isn't AS clear as it might be from the context?

Nobody gets to let go any good database team this side of sanity for whatever reason.

Nevertheless I didn't phrase my comment as thoroughly as I probably should have:

"Working safely with" any asset class data store just shouldn't ever be a question without immediate answers. On going development for the same pirates, doesn't provide executive management with solid answers to "define safety issues present future and potentially retrospectively debugging any failure".

10TB primary dataset isn't considerable amount of production in valuable chain scale of store. Default not a large database on any Oracle installation.

DBMSs require administrative rigors and procedures as well as ideally in depth theory of operations and definitely codebase development skills with the engineering and management system itself is extremely desirable.

However, I can't help thinking that here is a potential case of taking those undoubted talents to directly create proprietary variants of Postgres, which is only going to develop technical debts and future increase in nominally normative support costs.

In other words, I think that your talents have been inappropriately unleashed. You're brain surgeons and everything looks like a brain to you?

Unfortunately and obviously the mere mention of Oracle is liable to create greater difficulty in the creation of openly equitable technical discussions. Oracle management managed to perfect this awful disassociation effect I'm convinced purely for stress testing potential customers often in a gaighting style / hazing sales process . Check out the lady Oracle sales executive who files suit in California every year just to try and negotiate payments of some approximate order to her contractual commission deal. Not many smaller companies get much beyond that not inconsiderable corporate culture clash. I used to joke that Oracle sales cycles were a super proving ground for whether you have a growth business model or not. Because account growth is the keys to sales commissions and simultaneously your easiest leverage for getting big discounts. (Start from 50% before anyone says anything, kept our business afloat)

Ultimately I am unable to understand the point you're making, because you claim inseparable effects from tangential issues and not the smallest misrepresentation of my argument.

Being pedantic, neither of us ought to have used the word "purchase" in relation to licensing nigh inseparable from support and other fat margins. You can still buy a per socket license for RDB , however, and obtain the x64 40% socket discount if you can get VMS X64 running. Sometime soon I'm going to risk indicating that we've renewed interest in such a installation.

The problem I have with the engineering path you took is merely that for the scale and growth outlined, off the shelf solutions absolutely exist and some are thoroughly honed for optimal low administration and even lights out running. We're all potentially caught up in the limitations of early start up scaling of essential computer services, when ad hoc OSS wrangling definitely can sound more attractive than months failing to even understand the small talk spoken by the whole freaking teams turning up to sell you big company shrink wrap software. I'm going round this once again, and have cut myself the budget for dumping all non novel problems onto the most tried solutions. In other end, being ruthless to only spend engineering resources on strategic advantage absolutely can encompass a large license deal or two, but ironically whilst wanting to get rid of Oracle (together with historical deployment and tuning sins) is just that much more attractive a fictional moral campaign than holy war against teaching development teams about transactions on payroll. I'm cynical indeed, but I hope the circumstances are more clear now?

retcore··on The Ethereum merge is done
I wrote "no such logic [of adherence to formalized and academic research standards of claims and so on] .. doesn't exist in relation crypto culture."

I was clearly defining the entire practice of formal research as a null set within the crypto set.

Crypto culture is a compounds noun that's additive absent declination of sub distinction.

About Helium you assert that token has some kind to recognition and beau regard for- I really don't know what you're talking to but if I was sub editing your comments for clarity, I'd use the word Kudos. You claim this 5G access token has community kudos "glommed" or "attached to it" but in actually read the papers for Helium when first announced vector of investing adjacent to private 5G networks (UK Gov lets you drive truck throughout publishing network licenses awards since 2016) absolutely nothing but a more expensive convoluted and arbitrary code for the putative but barely functional exchange of on demand cellular next generation service.

If can possibly convey only one insight into what we're discussing to your everlasting benefit it sure would definitely be giving you a innate sense for why any discussions or even detailed research into things that you can build out of Lego isn't mathematical geometry or symmetry learning but model box picture building the prettiest parts you purchased.

retcore··on Debugging the Postgres query planner (2018)
Wow. Gocardless has over five years of engineering invested in scaling Postgres, and it was a on going development to enable them to "work with it safely"? At what point did operating safety concerns arise? I'm absolutely no fan of Oracle business practices, but this sounds like a story that sales can dine on for years, notwithstanding my private conviction that I could negotiate Exadata for less than the gross salaries excluding employer contributions.
retcore··on The Ethereum merge is done
Genuine research states claims for the methods and discovery, making it often quite easy to work backwards from the conclusions to the theory. No such logic seems to exist in the crypto culture.

retcore··on FLAC 1.4.0 released – added support for 32-bit audio
As noted in my third para :~)

Additionally from the product page:

"Unprecedented fidelity and detail, 130 dB dynamic range"

I've just realized that the product page I linked is extremely unusual for stating a dynamic range value.

However this makes sense if you read the papers covering Neumann's dual ADC and pre design of which they were justifiably proud. System D was a mid nineties introduction.

retcore··on FLAC 1.4.0 released – added support for 32-bit audio
>The TLM102 claims something like 130 dB. How much you care about distortion will depend on the situation.

Neumann makes no such claims. They do claim max spl of 144 dB. But the TLM and is 10 dB less and this is prior to ADC of variable ability. Distortion isn't a ceteris paribus value for signal to noise calculations.

retcore··on FLAC 1.4.0 released – added support for 32-bit audio
This unfortunately discontinued mic could comfortably exceed your claimed limits:

Neumann patented a dual ADC preamp to make this possible.

retcore··on Ask HN: What are examples of companies dying due to many people quitting?
>- if a candidate could withstand that company for that long there must be something wrong with them

Or just being exposed to a architecturally dysfunctional organization breeds negative behaviour and mentality.

Privately I consider this kind of behaviour espoused by executive management to clearly qualify as harmful to society surpassing criminal threshold. This needs concerted study however to form the basis of anything more than a grizzled opinion.

retcore··on Byte Magazine: Declarative Languages (1985)
Please forgive me for this flippant speculation - if there's a biographical record of those who died of self neglect presumably in despair please can you information or suggest sources* - but I can't help but thinking how much rebranding simply to CBM could have done for Commodore Business Machines. Granted, three letter abbreviations are jealously guarded commonly across industrial classifications, but usually specious and purely with pseudo legal hubris and wishful thinking. I may have just touched on a good reason why something like this wasn't attempted. I can't imagine the original Commodore folk going in for any superficiality or legal shenanigans let alone affecting their identity. Thus Tramiel set the tone for commerce in the computing age much more broadly, I'm thoroughly disheartened to imagine.

* not least because the industry was infinitely more (historical invocation of the word) artisanal and the work personalized, I very much want to read. If I may be so forward, it sounds like you have personal history close to this. I'm seriously interested in doing anything possible to help get history like this published with effective general reader marketing and can tap a variety of serious resources and experience.

retcore··on Sudden disturbing moves for IT in large companies, mandated by CEOs
Data science and tools are especially critical to oil and gas management. Including downstream: refineries are built for the qualities of available discovery and take as long to plan. Anticipating the availability, extraction costs and chemistry of a new deposit is a major advantage to anyone in the industry. I was given, cold, a six figure number of barrels of Kazakh crude to market, three years before the standard blend was assessed. That was fun...
retcore··on Why car wheels are so flat these days
Hang on, so multi tonne vehicles are designed with the rolling stock equivalent of anaerodynamic stability managed by black boxes?

I guess this is situated for latency but more likely installation and loom cost controls, close to the rear axle therefore more exposed to moving accident damage and at least to my casual reading of owner enthusiast fora unknown to educated owners and the public - rather like the Eurofighter Typhoon?

How can such designs pass DMV / MOT tests with inherent rolling instability in failure mode?

Or is there failsafe?

Edit: I should have said multi tonne vehicles intended by design to be driven fast and at limits including load limits.

retcore··on Vendor by Default (2021)
I thought that this was actually going to be a argument against vacuuming non commercial libraries and arbitrary codes, and a appeal, which I believe is a important consideration, for paid contract library maintenance classification, interop/bakeoff and testing. Clearly the possibility has slipped through the gaps between the plethora of open source foundations already established.
retcore··on Woman sues after DNA from rape kit used to arrest her
Here's a 2019 California appeal decision that on the most simple face of it would have invalidated convictions based on non consenting collection of DNA. In this particular case the appellant unfortunately for his fortune subsequently voluntarily provided DNA samples. Whether this could theoretically be overturned on lawful search grounds for procedure and investigation leading to arrest is my speculative question.

retcore··on Jean-Luc Godard has died
It's definitely slow, but I don't know what else could draw you into the social intimacy that's dissolved with devastating emotions engagement later in the film. There's a tolerance and intimacy established in the first scenes that I believe fuels the culmination of disassociation in self destruction, despair and rage in the numerous infamous scenes I'm uncertain could have had as much impact otherwise. Another theme may arguably be counterpoint between tolerance or understanding of mediocrity and individual desires for inestimable even incomprehensible realization both in terms of ff everything (the simplest contemporary expression become inseparable from New generation post Viet Nam national identity, and seeking private assessment when all meaningful references are lost. These are only some is a frequent contemporary messages conveyed by making seventies filmmakers reflecting a crumbling human infrastructure. It's possible to imagine the contemporary viewer, as I once could, appreciating the establishing scenes as something other than vicarious observation and more akin to a negotiation of sympathy and even solace. Today, I find the same extraordinary and beautified scenes, Cimino foreshadowing Heavens's Gate hubris had the winter location grass and trees decorated with green paint and faux foliage only for color balance, frustrating. We're ostensibly living in economic good times in unremitting contrast, and yet so little seems to have changed. I'm eagerly looking forward to viewing the moment I can discard my present perspective.
retcore··on AWS, Google and Azure demo of modern mainframe card application
What's modern or mainframe about this since the entire application is transpiled COBOL courtesy of MicroFocus (which I have memory of from another non adjacent decade) and the underlying VSAM record structure which is simply ETL'd?

Before submitting this I double took because I first encountered Microfocus migration tools in the early dotnet days, because I was wondering if I missed the possibility that AWS has a JCL runtime. Then I realized that the portability claims meant that everyone would need a JCL cloud runtime, which is unlikely, and you can find the Microfocus JCL documentation here: https://www.microfocus.com/documentation/server-express/sx51...

This is still a CICS implementation. I happen to think CICS, sanity checked, is invaluable. But licensing costs are commensurate with IBM philosophy. MTS Microsoft Transaction Server that appeared in NT 3.1 and justified learning to lock down the object interface security of every dll we had on disk back in the day (NT group permissions all the way down to SYSTEM heterogeneous masking of what can possibly talk to what. Wanna run notepad.exe without written sign off, nah. These boxen were on public IPs.) Such was the licensing value proposition. MTS has long been deprecated. But it's impossible to quickly appreciate what free transactions with mainframes meant in 1995. This should be leveraged again for the current multi systems and legacy parity cloud.

Microfocus JCL runtime I think is unique, deriving from a Seven Dwarfs hangover reverse engineered codebase.

Thus nothing here is open or cross anything without Microfocus licensing. Not inexpensive iirc. And I couldn't imagine that without support even if my experience was recent.

Edit invaluable not invalid about CICS. How is Chrome changing the literal meaning of my writing with complete word substitution /after/ I've seen my original intended word on screen for minutes and made no change in my text whatsoever? :: Ed2 added question mark.

Assuming that you could safely grant forgiveness for crippling debts, which I have long held responsible, along with property taxes, for wage inflation among my peers, does anyone else think that we might just manage a simple majority in favour of such a egalitarian pay system? I'm thinking there's still remaining enough undiscovered wealth accessible to the entrepreneurial mind regardless of absolutely income.

Remembering the horror that was my first encounter with a description of MySQL as a DBMS, by a far from newly minted* WordPress hosting entrepreneur, the greater difficulty may be overcoming cultural cognitive dissonance that Database != MySQL.

*as a Flash website developer my friend wrote a blood insulin device graphic from spec so completely down to knowing time drift, his unintended emulation was used for regulatory approval purposes.

How Oracle never capitalized on acquiring MySQL as leverage into small businesses via WordPress beggars my belief. But I'll wager that the kind of problems discussed here come into it.

retcore··on What exascale computing could mean for chemistry
Can I ask you what's standing in critical path to obtaining scientifically efficient compute?

Asking as a private user of commercially non trivial compute, but very short on the research depth required to translate optimal thinking into efficiency.

Edit: we're similarly bound by eg PDE solutions. We've found the greatest improvements in rolling our own storage. Not purely capex improvements but orders in ingest.

retcore··on Heavier cars are safer for their drivers, but far deadlier for everyone else
Instead of insurance deductibles, how about a third party accident claim payout strikeout limit? It could be quite high, say a million dollars or two, but this would still open the driver to unlimited liability for litigation in the event of reckless negligence litigation claims.

I would also set a mandatory minimum compensation level to unrepresented accident victims in a similar range, possibly paid in escrow for medical expenses and family care.

My thinking is partially in response to earlier comments about the wealthy just not being bothered by the cost of their own relative safety while driving the heaviest vehicles. That really ought to be tested imo.

retcore··on Byte Magazine: The C Programming Language (1983)
From personal memory in publishing in the early nineties, USPO rates publications carrying less than a third of paid advertising pages as first class postage. A impossible cost. This had the useful effect of ensuring that unsold pages went at steep discounts, increasing as your imposition deadline approached. Imposition is the DTP term for layup, the arrangement of pages over a webb offset press to paginate correctly after folding and cutting. With inventory so many options expiring P=1 worthless, I ended up involved in a kind of early computational advertising business. What was very different and impossible to find web publishing equivalent for, was the far better observabity and discovery of the pre long tail in print advertising trading. Lots else looked much like it superficially does today for online.

Incidentally I think that multi month circulation delays were almost always caused by the International Postal Union rules for Direct Injection of bulk mail at wholesale rates. Very small countries you'd need a minimum of 5,000 items per lot. IPU rules effectively created a hysteresis inflection around global readership acquisition and acquisition costs that pumped advertising price cycles.

retcore··on Tips for Developers Who Want to Build a SaaS Startup
But big expensive machines and software sales usually involves a lot of customer research and pre sales intelligence and rocking your sweet lone self (allowing you might be able to fake the roles and personalities necessary to mimic a remote team) to a enterprise closing meeting, isn't going forwards. Possibly you could look for interim executives from among the growing pool of experienced management exiled by industry ageism. But this(and my other suggestions) do require a broader professional ability. Enterprise software sales seems to have suffered something akin to job title inflation in IBs and start ups. And I can buy a lot of enterprise software directly online even in single digit seats. If you can do any of what I just pondered, almost certainly you're better off using your energies to hone your customer product fit, Steve Blank style or any which way.

The only thing I'll differentiate in my thinking from the OP advice is consider thoughtfully how well you are served by diarizing your development process and how much more can come from thinking in reverse from the customer perspective.
