quags··on Scores decline again for 13-year-old students in reading and mathematics
The minimum should be to ask what happened in school , how’s home work is it done and seeing the work sent home. It isn’t hard to see how engaging school is and what they are learning instead of waiting for gasp…test scores to go down. Some of these responses look like they are guesses from people who aren’t in schools or don’t have kids. Seriously 10 min from the above you’ll have and idea of how school is going.
quags··on Scores decline again for 13-year-old students in reading and mathematics
In my area this did not happen I’d be surprised if it really was anywhere. Remote as an option has been gone for some time.

NJ has overall decent schools that are well funded with huge local control in many areas broken up into an insane number of small towns. The kicker is all children need to have a minimum education regardless of cost - so if an educational plan needs multiple teachers following a student cost is no factor and I don’t think that’s a bad thing. The richer towns subsidize some of the poorer towns as well. I think that if a private school were to get any public funds at all they immediately should also be required to at no extra cost to the sender have the same requirements with out being able to get rid of problem children.
quags··on The Owner of San Francisco’s Largest Hotel Is Just Walking Away
This is less interesting IMO when going over the SEC filings of the company. These loans were coming due in Nov 2023, at what would be higher interest rates, and average bookings and occupancy for their portfolio are only 79% of what they were in 2019. It makes for a good story about how shitty San Francisco has become but likely would have any other hotel in this REIT. They operate on rolling over mortgages continually and after more than a decade of low interest rates this roll over greatly effects free cash flow - after hotels got crushed during covid for 2 years and still haven't fully recovered. Also, it appears the hotel is still operating, so how they are just walking away I don't know. Don't worry about the company, while they can't roll over their mortgages they have enough cash flow at the moment for their dividend and buying back $100 million of shares in the last year but do still have billions in debt to roll over in the next few years so if interest rates remain high expect more.
quags··on Our model suggests that global deaths remain 5% above pre-Covid forecasts
Perhaps but I’d argue society has moved to where this is better (children must have an education) vs the alternative say getting a job or whatever children did 100 years ago. Also it is being paid for, at least in my area, through quite high property taxes where over 60% go to school. So if the alternative is find day care or educate them myself I expect my taxes to go down where I can use that money for education and day care.
quags··on Dragonfly – Performant in-memory data store
First let me say redis has served me well for years. Before rspamd I used spamasassassin - another perfectly fine piece of software. Having more options is a good thing. For redis I started with single instances and moved to master (for writes), slaves (for reads), or sharding/hashing depending on what rspamd uses. I moved one section so far to dragonflydb called reputation module. This is performing better for my usage.

As for email, if email was broken down and nicely distributed over the same period I likely would have no issues. However, there are times where there is much more scanning going on, and a good 4 hours of peak time. This is where issues can crop up. If rspamd scan can't get a return fast enough, that test will be skipped. It still works, but I'd rather have all tests go through. So lets then take a single email and where redis is used

*Ratelimit checking

* Replies plugin

* Some multi map are stored in redis

*mx check module

* neural module (a bit like bayes but automatic and short term)

* fuzzy module used from spam traps

* history module - for redis admin, stats

So a single email is doing more than a single redis query for each email. The mail server (for smtp), which is not rspamd, is also using redis on its own.

Now imagine a spike of emails, perhaps a large spamming activity that is being stopped. Needing to scan 100 emails in a second isn't impossible at peak. The scanning is also for incoming and outgoing email.

quags··on Dragonfly – Performant in-memory data store
I use redis with rspamd and have systems that scan millions of mails per day and redis is a bottle neck for some of the modules. I’ve been impressed with dragonfly for the reputation set which has stopped the timeouts I was seeing and was able to replace a multi redis set up using rspamd internal hash/sharding to a single dragonflydb. I plan to replace more over but need stream support which is coming. The dev is also responsive on their discord channel.
quags··on Neeva, would-be Google competitor, is shutting down its search engine
“Alphabet cash on hand for the quarter ending March 31, 2023 was $115.102B”

Bard also seems like a reasonable competitor to chat gpt.

As someone with kids YouTube is king.

Google search and ad network could be declining, Facebook did certainly enter their market and take some share. But the revenue per employee is high , and unlike say ibm of the past I don’t think google yet is in a decline like them - and ibms decline started in the 90s and they are still around.

I’m not the biggest google fan but even if they shrunk by half with their cash pile it will only take buying a growing company, or one more good investment to keep going.

quags··on WeWork has frittered away $46.7B in value as the stock sinks below ¢50
This model is probably workable, but more under a airbnb type model where other people hold the liabilities and rent over a platform. The parent (ie wework) would take a cut, and companies could lease excess space over the platform. Instead wework holds the liabilities, which they got at high values, and now can not rent them. There was a long bull run, and money was flowing at many types of different projects - many which have or will end up failing. It is the same cycle as in the past which really shows itself after a few years of the run where suddenly it seems bear markets can't happen again, dumb ideas are making money and if you are not in you are loosing out. Covid led to work from home, which really killed wework's concept, but if it wasn't covid it would have eventually run out because it didn't make any money.
quags··on The professor who made $10B by cutting Google its first startup check
One thing with investing is you don’t need to be right all the time. It’s show more here with huge returns but even picking individual stocks a few winners tend to massively outperform the losers as long as you are not doing something like buying massively on margin.
quags··on America's Surprise Revival: The Suburbs
As I read this I wondered based on Texas and Florida bussing immigrants out of state - will cities just start bussing their homeless out to the suburbs.
quags··on Prop. 12, on humane sale of pork in California, upheld by Supreme Court
I run a business and need to comply with California laws. By extensions really everyone benefits but it is a running joke that California is always problematic. These so far include stricter privacy laws, stricter automatic renewal and cancellation laws, stricter pollution laws on cars , better gas mileage, and of course the this product causes cancer prop 65 on many things. I’m with the Supreme Court on this one. If farmers in Ohio don’t want to make the changes they can forgo the market and sell to the other 48 states ( I think New York is similar ) or see where the next generation is probably going and move to a humanely raised pig. Obviously they are killed In the end so humanely raised is a misnomer. I do eat meat but am well aware of the downsides, especially as a pet owner myself. norm McDonald said it best - there is really no argument here except I like pork and want it cheap. If I set foot into a slaughterhouse or saw these cages in Ohio I can’t imagine I would be ok with it.
quags··on Ask HN: It's 2023, how do you choose between MySQL and Postgres?
For myself it’s about what I know and that’s MySQL / Mariadb

If there is a problem I have probably seen it. MySQL won’t start for some reason I know what to do. Adding and removing users , permissions, running with selinux, optimizing queries, indexes - all with in my scope. Backups and restores, working with snapshots, MySQL relocation or master slave. I have been able for years to upgrade mysql versions with out much hassle. I know the table structure well enough I could downgrade in almost all cases - with adjustments I once downgraded mysql 8 to 5.7 because years ago it was too slow.

Now if I had the desire (I’m not past 40 so meh) or i didn’t have such a difference in knowledge I’d probably seriously look at postgresql. So my suggestion is go with in your circle of competence. Regardless if you go with mysql it is a fine database that many use at a high scale.

quags··on Go with PHP
There are breaking changes from 4->5->7->(less so)8

This is why so many basic php web hosts continue to offer older php versions because the old code will not work and why paid projects like cloudlinux hardened php still exists. Just in the last 2 years they finally ended security support for php4 on the hardened php project.

So to explain how it worked, it wasn’t as sudden as python, but the problem areas have been depreciated and removed as php has evolved.

quags··on Pure: No more hard drives will be sold after 2028
I’ve done three recoveries to a remote service for clients - the first failed and two which were ssd had a full success.m but all were ssds. Hdds I never sent to recovery because generally they were not complete failures (ie some bad blocks and a copy around was possible ) or the board could be replaced to fix it with the same model and firmware.
quags··on YouTube tests blocking videos unless you disable ad blockers
YouTube was also unprofitable at the time. With out google backing youtube it may have gone the way of Napster.
quags··on Why are lithium prices collapsing?
Has there been a commodity that has spiked in price due to true lack of supply and non new supplies were found? From peak oil, to copper , lithium and rare earth minerals predictions of we will run out during a price shock always seem to turn into a price collapse.
quags··on New York to ban natural gas, including stoves, in new buildings
This covers new buildings. All the old stoves and infrastructure stays and there is no need to replace the existing stoves.
quags··on New York to ban natural gas, including stoves, in new buildings
NY does get some amount of power from out of state while it having any coal plants in the state but - edit - it seems to be less than 1%. Now I actually wonder why NJ has so much coal power compared to ny.
quags··on Rate The Landlord: Anonymously share information with tenants like you
I can’t speak for other states but there are a number of protections in New Jersey where you cannot easily be kicked out as a tenant with out going to court including things like non payment. This was before Covid added further protections which some have been rolled back.
quags··on Wind and solar are now beating coal in the US
1) I don’t see how this is a problem. First we are not only dependent on these and have a mix of natural gas , nuclear as well as coal. Out of all coal is the dirtiest for direct pollution into the atmosphere. If we can reduce or eliminate coal by replacing it with wind and solar that is a good thing. Technology will improve to improve storage.

2) while this is an issue coal has been declining for some time. There are health issues with coal and the jobs have been shrinking and half of coal jobs have been lost since 2012. This is with coal usage higher today. The jobs will continue to be reduced regardless. Part of the 2 trillion dollar infrastructure plan includes training and assistance for jobs like coal miner lost. That is the best solution possible for jobs that will not exist in 100 years unless there is suddenly a new purpose for coal.

Nacco industries for example is expecting the closing of one mine and plant this year in Texas. It is attempting to diversify into lithium and other minerals. There is a small fight from at least one state senator that may keep it another year but over all it’s not economically viable to keep it with other alternatives.

quags··on Sperm counts are declining. Scientists have pinpointed the main causes
Do we have a good amount of data for speed counts in the past? I have never had a count and I assume unless you are in a situation with fertility issues , are donating or part of this study a count has never been done.
quags··on Google announces Q1 2023 earnings [pdf]
I remember the ipo and also not buying because google only has search and that seemed to be an issue for me. I remember the ipo being botched. Also I didn’t buy apple thinking while the iPod was nice one product won’t bring a company back from near bankruptcy. Both companies are over a trillion dollars, have significant cash and if you bought and held you would be doing quite well. This was also during the most decade of Microsoft where people were predicting the down fall of microsoft too. So it’s hard to really gauge what a company with so much money and low debt can pull off and continue to grow.
quags··on Tell HN: Expect you may have to write off Microsoft if you self host email
I know people are saying it’s your isp and that is a possibility but IMO ms is being too harsh here. First let me say at least they have a support department unlike gmail. As for your isp I honestly don’t get a significant amount of spam from digital ocean or many of these vps systems so I don’t think it fair to say that is the problem right away ( this is spam only not ssh brute force scanning which I don’t track ). I get significantly more spam from aws, gmail and Microsoft itself - I’m personally annoyed that these providers are too big to block but have no issues blocking other ips with no ability to resolve it. Sorry I have nothing to add to help resolve this. A month ago there was a post on a similar issue but with gmail. At this rate the response will be the problem is you are running your own email server and should pay for delivery.
quags··on LVMH becomes the first European company to surpass $500B in market value
A look at some of their financials has the trading at 32 times earnings where Apple trades at 28 and Coca-Cola trades at 29. So for luxury that doesn’t seem too high and from the list I have heard of a number of their brands. There is certainly value in a brand name, which is why I used two examples of other known brands in other industries. This lvmh company though is also growing at almost 20% per quarter. My guess also is during a mild recession luxury goods tend to hold up. While I wouldn’t buy it myself because I know nothing of luxury goods based on the businesses I see listed not all in clothing which I had assumed I would say the brand names may not be as significantly valued as one might think.
quags··on YouTube, the jewel of the internet
7 and 11. My kids also like the same things but enjoy the shorts about science, space , microbiology, one minute animals and the bees.
quags··on Why Perl?
CPAnel is popular with shared hosting and is predominantly Perl. Companies like godaddy and eig as well as thousands of shares host still use this. Certainly a shrinking market but it has a number of years in it. Apache spamassassin is written in Perl. Other than those I rarely ever see a Perl project and if I do it was originally written in 2000.
quags··on Netflix will end its DVD service after 25 years
I used to get dvd cases, burn the disk after using dvd shrink to make it for on the disks I used then print out a coved and labeled the disk with the name and IMDb rating. I amassed quite a library but there were many I burned and never watched. These eventually moved to binders and have probably been over 15 years now. I wonder if they would still play.
quags··on 60 Minutes asked Google CEO: “Have you killed your cash cow?” [video]
Google looks to have 100 billion in cash. IBM has been slowly shrinking for years trying to buy into new markets and maybe they have with red hat finally. Google doesn’t have the amount of employees ibm had either. They may shrink and loose search but have a long run way to buy or pivot. Microsoft is back on top after 10 years in the 2000s in their lost decade. Apple crashed out at least twice and came back, once because of cash and low debt. I would not count google out just because of their cash position and getting rid of their ceo probably would be a good first step.

If you are really interested in selling and getting the best price find a company that specializes in selling tech companies. In the space I operate on dhcapital is one who handles some of the technology space and would likely understand an app. For multiple - not sure what an app gives now a days my guess with higher borrowing costs is it would be a multiple of profit and not revenue. Other options are seeing if there are any larger dating sites who may be interested. If you are not getting direct unsolicited offers to sell and don’t want to go through another party to sell use your profit margin to do some targeted ads and try to build brand to get noticed by a larger company.
