Ask HN: Single best practical advice from your expertise?
Recently I had a nice meetup with some old friends and colleges (for the first time in more then a year!), where we each ended up sharing one single piece of simple, good and practical advice or habit from our professional career and experiences.

Two gems I'd like to share here:

- From the manager in our group: He plans and extra 10 minutes for all his meetings, and starts the meeting with all the participants silently reading the required documents that will be discussed. This change made him and his team pretty happy: everybody now knows what they are talking about, no one has to be uncomfortable joining a meeting without having found or taken the time to prepare.

- The sysadmin/ops guy: This is one lazy dude, your average BOFH. He has this nice trick that saved him a lot of work in evenings or weekends: for every machine or container he builds and installs, he puts a large empty file in every partition on every disk, taking up about 10% or so. `dd if=/dev/zero of=bigfile bs=1M count=1024`. This file just sits there until he gets this emergency call from a user about disks being full, usually at the most inconvenient time. Instead of frantically having to spend hours in the weekend migrating databases, expanding file systems, mounting new volumes and what not, he simply SSHs into the box, removes the file, and goes back to barbecuing and drinking his whiskey, and will properly solve the problem in office hours come monday morning.

I find both of those excellent pieces of practical advice: so simple that it makes you wonder why you never came up with these things yourself.

I bet the people of HN have more like these?
Apple's “1984” Macintosh Commercial
The usual for bad Internet debating and communications: Attack the person and not the arguments. If you have some credible evidence, trot it out.

It is my writing here that is rational and the responses to it that are irrational -- my post was down voted and "flagged" out of view with no meaningful responses.

Again, the alarmist predictions of disaster were made and found wildly wrong; I referenced the data.

Bluntly no one knows how to take data on CO2 from human activities and accurately predict CO2 concentration and temperature or in any meaningful sense the effect of the CO2 on temperature. Nearly all the attempts to do this were wildly wrong.

The global warming alarmists are as irrational as using leach bleeding to forestall another eruption of Yellowstone, of old religions making "sacrifices" to ensure good climate. The Mayans killed people to pour their blood on a rock to keep the sun moving across the sky -- the global warming alarmists are following the same irrationality.

Since my post was "flagged" out of view, I will repeat the post here now:

There is a lot of hand wringing, worrying,
blaming about evil, short sighted,
negligent, irresponsible humans doing
serious damage to the environment and the
planet and causing disastrous, dangerous,
destructive world wide climate change,
global warming, rising sea levels, etc.

There is no end of what we can worry
about, e.g., Yellowstone erupting, another
Krakatoa, having the atmosphere of the
earth blown off by the blast from a
supernova, etc.

But just now the claim that human sources
of CO2 are having significant effects on
the climate, temperature, sea level, etc.
are the source of a lot of angst and
anxiety.

So, we need to filter, separate possible
disasters for which we have good evidence
and can do something about from the
endless number of disasters for which we
have no credible evidence.

For human sources of CO2: So far there is
no, none, nichts, nada, nil, zip, zilch,
zero credible evidence that human sources
of CO2 have had, are having, or will have
a significant effect on the climate,
temperature, sea level, etc. No evidence
that is credible.

All the credibility was lost, blown,
thrown away, destroyed by the many
predictions of significant temperature
increases that didn't happen, as in the
well known

http://www.energyadvocate.com/gc1.jpg

As a result, the alarm, angst, anxiety,
hand wringing about human sources of CO2
is irrational, foolish, irresponsible, and
supporting an industry of hysteria that is
just a flim-flam, fraud, scam on the backs
and in the pockets of billions of people
and making a few people rich.

While we know very well how to measure
temperature and how to average it, we
don't even have meaningful measures of
climate.

For the science that might be relevant,
essentially all of it fails to be science
because it has long shown to have no
predictive value.

In response, until there is credible
evidence that human activities can do good
things for the climate, we should just
junk the alarmists and forget about human
sources of CO2.
I switched to an iphone about a year and half ago and I’m feeling it too. My current plan is to switch to a lineageOS device. Apple has completely run off the rails in the past year, from aggressive politicking to now complete abandonment of their core values.

I didn’t even realize apple had the ability to do something like this? Can someone explain how this is even possible for them to do? This wasn’t an update was it? Just a flipped switch?
No one was talking about serving from application directly. The issue is in scenario you are describing. Please read the article.
Obesity related conditions are some of the leading causes of death. There are also advantages to simplifying your lifestyle and expenses. Sometimes less consumption can be an end unto itself.

We can disagree about climate change and the rest of it, but the results of a sedentary lifestyle can't be ignored. There's also no room for indignation at an imagined holier-than-thou position when you take this approach.

I've found this simple, obvious observation about obesity especially interesting in regards to the current public health scare and the rise of the bio-security state.
Re: Twitter image link - This is why you should never ever trust any corporation and their marketing BS. PASS LAWS INSTEAD.
Just take a mobile device and avoid matching it to any identity, if - like many - you have needed pocket computing power since forever and since forever you have been a private individual.
What is the object scanning ecosystem?

As a hobbyist I can grab a bunch of photos of an object, feed them to photogrammetry software such as Agisoft Metashape, export the generated 3D mesh and convert into watertight printable mesh using Meshlab.

Is there anything else out there?
The latter is not a valid use case for anything using signatures, because it² is virtually impossible to implement correctly.

The former might be important for something? But generally also very nearly impossible to do correctly. When that is the case, one should contemplate whether the actual business requirements can be fulfilled another way, instead of making things broken by design.

² "canonicalize-encode-sign" as opposed to the correct way of "sign blob, parse blob".
Why is it backward? Unions enable general strikes which enable wide-ranging policy changes.
Im guessing there is some kind of performance issue here. Where large or certain kinds of archives can have huge unzip times. Or especially that it is hard to determine the unzip time before unzipping.

Google drive drops a lot of features that are technically easy because there is no fast or constant time to perform the action.
What If Facial Recognition Technology Were in Everyone’s Hands?
>There is also meant to be human verification of any flagged images.

That shouldn't make anyone sleep soundly at night. The person at the other end has no incentive to not turn your life upside down.
So we have a person that is technical enough to find known CP, so the stuff that's already automatically filtered out by Google and co because those same hashes are already checked against for all images they index. So knowledge of dark web should be assumed, something I don't even know how to use let alone how find the filth on there.

Yet....dumb enough to upload it unencrypted to iCloud instead of storing it in a strongly encrypted folder on their PC?

The two circles in this diagram have a very thin overlap I think.

Dumb move by Apple, privacy is either 100% private or not private.

Unless somebody can enlighten me that like 23% of all investigated pedophiles that had an iPhone seized had unencrypted CP on their iCloud accounts? I am willing to be proven wrong here.

I have never heard the brake and tire argument, but it sounds like the 'batteries are worse for the environment than gas' argument which is not very accurate.

Makes you wonder if there are companies who benefit from information such as this being believed. Companies such as Shell maybe?

Edit: Not saying it isn't true! Just saying there might be more sides to this.
The issue is that the very concept itself is limiting and thus limits how we can interact with the computer. The concept of files and directories is a direct analogue to a filing cabinet.

The concept of how the information is stored is no different. It just the amount of data that can be stored. While storing more data that can be copied, transferred and edited easier is an improvement. The fundamental concept of the file system itself is still wedded to a concept that is probably 1000s of years old at this point and by tying us to these concepts it limits what can be done with data within those files.
Not sure if it's only in Great Britain where this occurs, but the food manufacturers have taken the acronym WYSIWYG to heart.

Don't expect anything more than what is visible in the food packaging.

The little plastic window in the packaging shows lots of pepperoni?

Don't assume the whole pizza is uniformly covered in pepperoni.

You'll just make an ass out of yourself.

see https://www.dailymail.co.uk/femail/food/article-5274153/Phot...

I've seen pix of sandwiches where the packaging looks like there's tons of filling only to reveal that all the fillings have been jammed to the front of the package window.
This is quite an interesting phenomenon unfolding.

Those with high-CO2 performant genetics may have better cognitive development in the future.

(Also, it's sad to see kids wearing masks all day with zero regard for the science on CO2 concentration & health).
Maybe anecdotal evidence, but I've read multiple posts/news stories about people affected by sanctions because of a shared name. I figure that if there was an issue where PhotoDNA had actually led to someone being arrested, that would have made headlines somewhere, at least here.

Can someone clear this for me, why wouldn't the author sue the bank which locked their cash?
Temple Grandin's corridors provide a stress free roaming path for the cows that feel the urge to be milked. The corridor ends with a proper curve that makes the cow stop right above the ground mounted camera that is trying to capture the teats. The moment the teats are visible, the mounted and immovable milking robot reaches out with the hand and is trying to catch on the teats with the feedback from the camera. Eventually it latches on and sucks around 20 L of milk. The cow for some reason stands still during the whole process and after it's done the cow continues forward, making room for the new cow that is waiting in line.
> It’s a common name, like Robert Brown or Mary Johnson. Shouldn’t it be easy to prove that I’m not person X?

I wonder if the problem of a post author could be resolved by changing his legal name to some unique name?

And, consequently, a sanctioned person could probably do the same to avoid sanctions.
As I understand it, overfitting is low bias, but high variance. It's perfectly fitting 5 linear data points with a complex polynomial, when the underlying function was a line. Thus the polynomial doesn't generalize well to more data points not in the training set. Your model seems to be fitting points in the training set and the evaluation set just fine. Of course if different batman's were in the evaluation set, it would suddenly be doing terrible, but you can pretty much do that to every machine learning model. It wouldn't fit a lot of underlying assumptions of statistics and machine learning, eg i.i.d and evaluation sets/training sets being from the same distribution. Your definition of overfitting thus seems more like transfer learning, in some sense.
What if you send a photo to an iPhone user that is gets false-positived, aren't you also at risk?

Basically, is it with interacting with Apple users if you are worried about that problem?
NYT/SWJ/BBC used to have much more rounded coverage of China. Look at their China coverage before and after four years of Trump. The difference is stark. The entire political environment regarding China shifted drastically during the Trump administration, and that's reflected in both opinion polling and media coverage.
So Apple is putting a database of child pornography on my phone ?

I’d rather not have that on my phone.
Now we just need to place a photo on our opponents phones - journalists, politicians, someone whos job you want, you name it - and their phone will call the police itself and bring the proof too, and it's their burden to prove their innocence.
COVID vaccines are not basic child healthcare, heck they are not even approved for children under 12 and in many European countries not for children at all

also not sure how necessary is to take nude photos of children unless you are doctor and yes I am parent with 2 kids

taking care about your health and not willing to risk long term effects of unproven stuff someone is putting in your body seems perfectly natural to me

Folk etymologies based on acronyms seem to hold a peculiar power over people's imaginations, irrespective of how obviously false they are. I remember as a lad being told that 'news' was so called because it came from the north, east, west and south :eyeroll:

In other words: one more reason why it is exactly like Mac 15 years ago?
To a degree, but a lot of potting soil is sterilized so the "life" you're interacting with is pretty incomplete.
The issue here has nothing to do with children, they would always use 'children' as excuse. The issue here is installation of Spyware Engine.

The very fact of existence of such Spyware Engine has effect that each person would behave as 'someone is looking'.

This means zero privacy. This means 'no privacy' feeling. Everyone is more 'careful' when people around. And this has prolonged effect on society's freedom, democracy and rights of individual because independent thinking happens when true privacy is there.

Even a fear of false triggering the system and exposure of one's private thoughts/pictures/events to other people during 'sorting out false alarm' would make people behave differently. Even if they have nothing to do with any children the fear that their private moments can become public just because some AI would decide so would make each person think twice about each step.

This is a huge attack on privacy of individual and should not be taken lightly. The effect will be also huge. Just imagine what they will do next if they get away with this. Just imagine what other companies will do once this is accepted for apple devices.

I think this can/should also be considered as a fraud because when one bought apple device one was never told that spyware would be installed some day later.

Edit: I think it should be illegal/made illegal to install any spyware on any device for any excuse without warant. Spyware is a Search of 'home' without warrant to some degree, isn't it? Done through the hands of some private company under some excuse... What about Fourth Amendment?
Why would an Apache bug show up in Nginx changelogs?

I wonder if the fact that DNA & RNA only occur with one chirality tells us something about how frequently this step occurs in the Drake equation.
If the step from non biological organic molecules to RNA & DNA happens often, wouldn't we expect L-DNA and L-RNA to appear in nature?

> That is because rainbow tables cannot practically attack long passwords.

It's trivial to create a rainbow table that attacks passphrases. This statement is wrong. You example 1000102772901 is easily within rainbow tables. Trivially so, it's worse than a passphrase.

> it defends against comparing one user's hashed password to a second user's hashed password,

This has zero value.

I can only suggest you do a course on hash functions on Coursera, the mathematics is somewhat easy and interesting to know. It's fun to follow up with a Blockchain course also has very interesting mathematics around hash functions, I really enjoyed this.

I can't suggest which, the one I did isn't available, but check Google reviews there's a few out there.

They write the OS that runs on your iPhone, so of course they have the ability to do this or anything else.
I used to like this podcast but two behaviors by the host ultimately turned me off:

- Lex’s weird comments and massive oversimplification of ethical topics. He always seems to ask people if X is Good or Evil, with no consideration of nuance. I get that he’s a computer scientist and not a ethicist, but I somewhat expected more.

- He doesn’t question the guest or curate the discussion very well. Some of the episodes are 3, 4, 5 hours long, which is madness. I want to listen to his guests, but I can’t spend 5 hours on a conversation that has an hour of insight. This is the job of a good host.

Overall the strength of his podcast comes from the quality of guests. I wish he would take his role as journalist/interviewer a little more seriously.
I guess it doesn't matter, the smartphone is a tracking device by definition, they can track your movement with a dumb phone too, but there are much more possibilities in a device with recording capabilities and an internet connection. In Orwells '1984' they mandated the installation of a televisor tracking device, now they have one in every pocket, and so it goes that we traded privacy for convenience. It's a bit of an irony, that Apple started with the big brother commercial, and ended up bringing us the televisor. https://www.youtube.com/watch?v=zIE-5hg7FoA Just because opportunity for an exploit is creating the reality of using that exploit, it seems as if it is then used for it's intended purpose..

I know this isn't the answer, but I am happy to have a globally unique name.

I was lucky to have not one but two uncommon surnames. (grandmother remarried, children got an extra surname). There are only a dozen people with that combination of surnames.
Urghhhhhh! That is exactly what I don't want to hear. Lacks a clear plan? WTF? And how come "terrible" is acceptable then ?

I prefer unprofessional then :)
It is perfectly possible to get by without buying into the credit scam. You just have to do things the way they were done 50 years ago: present a recent paycheck, present a current bank statement showing that you have enough in the bank, get an endorsement or cosigner from someone with the monetary means.

Some combinatiom of the above will do and make sure that you are able to speak to a human. Of course, this means that its cpnsoderably more difficult to live outside of your means. It is almost as if systems were set up to encourage people living outside of their means..
A 'private entity' that tries as hard as it can be to be a monopoly of everything and has hundreds of millions (I won't say billions because I don't trust Facebook's own figures) of users that rely on their services

Search engines, Google or otherwise, tend to give you the right results when you search for an application. App stores are garbage.

> Putting an application bundle on your local disk anywhere is sufficient to get file type mappings to work.

How does this work "under the hood"?

"Bundles" and "packages" as a general concept are interesting. Lots of games from DOOM upwards use "packfiles", which are effectively lots of files in a never-unpacked container. You can't see them in the filesystem, because the intent was to avoid incurring filesystem overhead for them. MacOS bundles appear to have gone in the opposite direction: the structure is brittle (if you move anything it breaks signing), but it's unpacked into the filesystem.
I believe the initial rehousing of elderly patients back into nursing elder care facilities predates the arrival of the hospital ship and the construction of the Javitz Center hospital and triage space.

I'm ignorant on if this practice continued post arrival and construction of the added COVID treatment centers though.
It’s also intentional in that penitentiaries and prisons from the start in America were an incredibly racist endeavor. As was the response to the “crime waves” of that time period you mentioned. The early prisons, both private and public, were a Protestant method of punishment involving hard labor to cleanse you of your sins. But they were quickly co-opted as a way to make money, whether by labor for the prison itself or by the state leasing convicts to corporations. And after slavery as a way to keep African American people enslaved. If you’ve never seen documentaries on Angola, it’s horrifying the direct lineage of racism visible. Lines of black men in chains, in fields, picking cotton, under the watch of white guards on horseback…in the year 1960 and beyond. Wardens who had property on the plantation prisons of Arkansas and used black prisoners who weren’t in the fields as “house boys”. That’s always been and is today one intentional use for prisons.
