> Sorry, no, Venice isn't what I'd call a real city. It's a tourist trap. AFAICT, the only people who sleep there are tourists. The "locals" who service the place commute from outside of the town.

Sorry but no. The entirety of my mother's family still lives there, in the "city" city. A lot of people still live and work in the inner Venezia. There are some commuters especially from Mestre, but that is what you expect with any medium sized center with satellite smaller towns around.

Also "Venice" is quite misleading because aside the usual tourist destinations, the city has quite a large horizontal development inland. You contraddict yourself stating first that Venice is only a tourist trap with no locals and then stating that you saw local women buy groceries, and inviting people to visit the "real" Venice, which of course you saw, which of course has a resident population.

Your vacation-long experience might not necessarily reflect the truth.

I was thinking about the manipulation issue tonight. I'd been throwing a tennis ball in the pool with my kids and I realised how instinctual my ability to catch was. A ball leaves my kids hands and I move my hand to a position, fingers just wide enough for a ball, and catch it. All of it happens in a fraction of a second.

The human brain can model the physics of a ball in flight, accurately, and quickly. As the ball touches the finger tips it makes the smallest adjustments, again in tiny fractions of a second

Indeed. The topic itself is fascinating, but it doesn't seem like much too complain about.

The ugly part is when they don't line up the windows. Otherwise, it's fine.
Let’s insulate ourselves from the delusional masses by forming coalitions
(Obviously) Since you are reading this you probably know what I’m getting at. People who are grounded in reality are rare and may often be lost among the sea of the deluded masses( I'm one of them). So this post of mine is an attempt to gather people who are like-minded.( people who I deem to be grounded in reality through my own colored lens of the world). The idea is to form mutually beneficial alliances in this insane world. As to how exactly this is to be achieved is something to be discussed ( though I have some concrete preliminary thoughts ).

How to start: Email me your core beliefs ( though I personally prefer a voice chat with on Skype, google hangouts etc.), especially the beliefs where you think you differ fundamentally from the vast majority of people. I will quiz you on various subjects ( and so can you) to see if our beliefs align. Overall my beliefs can be loosely labeled as: generally anarchist (i.e a live and let live approach), generally anti-authoritarian ( meaning I believe govt/authorities do not protect your interests), largely capitalist( i.e vehemently opposed to coercive co-operation, put forth by typical socialism) etc. Perhaps at the bare minimum we have to share a meta belief that it is necessary to reach out and cooperate with other like minded individuals as it is virtually impossible to 'de-delude' the idiotic masses though arguments/dialogs etc. My email address can be found on my profile. In my profile you will also find a link to some webpages that outline my beliefs.

After this step, if we think our beliefs align, I will add you to an an online forum ( zero people as of now) , where you can interact with other people that I will be screening.

Caveats:

-It often takes a very long time ( months to years) to form mutually beneficial alliances. ( more so when individuals are geographically isolated from each other.) This is not a quick fix for your immediate problems, or for people without perseverance.

-The online forum is not to rant against the world, or a place to discuss your core beliefs. This is more of a place for doers not ivory tower thinkers.

It’s really hard to for me to believe that someone else is not doing this ( i.e what I’m attempting in this post) already somewhere. Let me know if you are aware of similar efforts, I would be eager to join.
The ones where the old and new windows don't line up always seem a bit dumb. Must be a horrible experience for the people inside the new buildings, looking out of their windows onto a brick wall a few centimeters away. Both cited examples of this (Artillery Lane and Caledonian Road) are student accommodation, so I wonder if building at ultra-low cost has something to do with it.

Many of the others I don't have a particular problem with to be honest. There's actually one (not cited in the article) on the adjacent street to where I live, but they're building the new house to match up with the old facade so the nice Victorian era terrace isn't really disturbed. I'd much rather that than what they've done on another adjacent street - some overseas developer has bought one in the middle of a row of identical terraces, torn it down, built an iceberg basement, and a big new "modern" building that looms threateningly over the other buildings in the street like a largely windowless slaughterhouse with odd disproportionately large misshapen windows in improbable locations. I don't want to sound like Prince Charles with his "monstrous carbuncles", and I accept that perhaps there may be some people that somehow find that sort of "modern" building somehow aesthetically appealing, but I can't see how anyone would possibly think it was in keeping with the rest of the terrace either side, and have absolutely no idea how they got planning permission in such a strict conservation area.
To think there are organisations whose sole purpose is to defend people who enter a country illegally. What a position of privilege to be in, when you are so rich that you don't care if wages are pushed down like that.
Ask HN: Help Calculating Cost of Acquisiton
I've read a huge number of blogs on saas metrics etc, but one thing I can't quite wrap my head around is calculating CAC in my scenario, inbound lead gen closed by an inside sales team, average sales cycle around 50days (im not trying to layer on headcount costs yet)

Acquisition

month0 spend : $10,000
month0 new leads : 500

Conversions to customer

month0 : 3
month1 : 5
month2 : 2

CAC

month0 : $3,333
month1 : $1,250
month2 : $1,000

Is this correct that the CAC changes over time, it makes it difficult to report a solid CAC number, and for it to be comparable month on month.
Or should i only report on monthly cohorts after month2 when the conversions have settled?

They blogs i have read, even where they have a longer sales cycle, appear to assume that all the conversions happen in a single month

Any input appreciated
'Facadism' is also getting popular in germany and I think there are some really nice examples here. If done well, i think it really achieves the best of both worlds. The buildings fit in and preserve the atmosphere and character of the city while also being modern, livable and built for their real purpose on the inside. There are some examples where it's hard to tell that in fact only the facade survived and the entire back got replaced, others archive a good harmony between the old and the new. I think it's a great idea! But, as always, poor executions can always be found (some examples can be found in the article).
Do you have any good resources on that Deming-style quality training?
The natural environment encodes "all the rules" for real animals, too. You need some constraints or else there is nothing to be learned. One could say that every survival task is also specific , but is a slight variation of previously learned one.

> pigeons predicting breast cancer with 99%

pigeons contain 340M neurons (with dendrites and all, giving them higher computational capacity than ANN units).

> Rodents stand a bigger chance at learning Go

They probably don't ; probably because they can't understand the objective function and their brain capacity is limited
I wouldn't want to live on the 1st floor in that 6th building , though.
I suspect the value of the seismic data keeps better over time than the value of the hardware, too.
Interesting that John Dykstra who was pioneering motion control cameras in Star Wars actually got some of the idea from working on a late sixties / early seventies Berkely traffic simulation that used a tiny city and a camera moving around.

Do you mean you use something like grencode to literally draw the QR code using Unicode box characters or do you just decode and save their contents?

As an extra suggestion: if you use an Android phone for OTP, [andOTP](https://github.com/andOTP/andOTP) supports exporting directly into a PGP-encrypted JSON file which can then be either imported back into the app or converted back to QR codes with a script.

Since it allows you to trigger the export using a Broadcast Intent, I have it set up to do that as a part of my weekly backup Tasker script (of course, you could also just use any other sync solution and manually export when you add a new code).
Building regulations for student accommodation are less stringent than for regular housing, so possibly these designs wouldn't be allowed otherwise.
Upgrade Board Turns Typewriter into a Teletype
I pretty much guarantee you that neither rural farm teens nor city factory working teens in past centuries were allowed to sleep till 10. They had to wake up when everyone woke up to work.
> Plus, the reason teens are not considered adults is not that their IQ would be low. The reason is impulsivity and similar considerations.

Maybe what we call "impulsivity" is just an healthy reaction against absurd constraints and monotony? We forget very easily that we are animals, and the way we have been living for the last few centuries is radically different from the way we were evolved to live.

Perhaps factory-like schooling is inherently painful, and what we call "adulthood" is just learned helplessness...

ICANN has made several decisions in past that are mind-boggling and definitely not in public good. I wonder who runs this org? How someone gets into leadership in there? It surprises me to no end that we are being forced to pay $$ perpetually just to add a little record in their database. There should be nearly no cost to this and over the time I've become very certain that there is quite a bit of bribery going on in ICANN who approve raising prices instead of slashing them. What are the avenues to legally disrupt/expose/fix ICANN?

I imagine they care more about the inhumane treatment, etc. Thanks for the disingenuous comment though.
Power, most likely. You physically couldn’t connect 4-5 full powered devices to a hub. There is an expectation that any USB-C port will accept any power any compatible device.
Lol the people leaving have other priorities than good code anyway, good riddance sheeple.
> Who has a problem with the current height of phones?

I do. So, now we've cleared that up :)
Some of these designs are great and others show the laziness and focus on cost-cutting in much of modern architecture. Just putting a new building behind an old facade is not architecture, it's copy and pasting. The true architects are those who manage to reuse the facade and fuse new and old into something that blends and flows together.
Here is another one: a highly effective programmer will never use a low contrast design for publishing text that somebody should read. Never. Low contrast design is a very good indicator for unawareness and non-thinking followers.

It is good advice to stay away from companies that publish low contrast things.

Actually, the news for me is that Oil & Gas exploration still has needs for computing that's considered significant today.

Basically, I can see that they needed super computers in the 80s. But I might have assumed that their computing needs wouldn't keep scaling with supply. So that by now, just renting some GPUs from Amazon might be enough.
I'd rather they put in a building that actually uses the facade they sit behind, in keeping with the architecture they supposedly want to preserve. The examples where it's just a wall with new style building sat behind look awful, and the windows don't even line up - so probably very inconsistent light, times of deep shadow and limited views from inside.

Looks more like the sort of thing your neighbour might do if they were a builder and you'd really upset them. :)
why is this so important why do you consider him such a genius?
There are many vision models where classification is better than human. I m not sure what you mean 'fall of rapidly'; they do fail however for certain inputs where humans are better. But we 're talking about models that contain 6 to 7 orders of magnitude less neurons than an adult brain.
It was a big hit in the US, where Nokia was non existent. For a lot of folks this was their very first mobile phone, I’d say the equivalent of Nokia 3210/3310 in Europe.
But yeah, unlike Nokia this wasn’t the best device on the market.
I concur. I wondered whether their patch hit AMDs as well. Unlikely, but not entirely impossible, at least to me after hearing news about Linus "commenting" on their practices of creating problems for everyone.

This is obvious in foresight. That picture shows literally the first image I had in my head of how they were going to have fixed the problem.
Carmack is amazing at computer graphics and related technologies, but I fail to see evidence of the other two areas. He's never been much of a businessman - he's always focused on the technical side and left the selling/operations to others. I'm not aware of much he's done in terms of educational explanations, and the talks of his I've seen have been rambling and convoluted (but fascinating!).
This happened to me a couple of years ago. Lost my phone, no recovery codes, so no access to github. Contacted support, they told me that they wouldn't be able to restore access even when I was communicating with the email associated with my account.

Luckily I only had public repos, so I created a new account and forked them all. Support had told me that if there isn't any login activity in the blocked account for a period of six months, they would delete the account and release the username. And yes, I had to follow up after six months were up to make that happen.
Awesome, thats a step in right direction i believe

Apple did have impressive build quality, but those days are long gone. I can run happily on a MBP from a few years ago, whereas the newer ones have had numerous issues.

In terms of overall quality, I'd say that MBP is now behind some of the other high-end devices. The Surface Book knocks the latest MBP versions out of the water in every department, except for the track pad. It's not difficult to argue that the keyboard, screen, durability, or even the OS is superior to Apple's (current) offering.
Something I'm interested in is a knock-about computer for child with a text editor and a programming language. Robust enough to put in a pocket. A hinge, or larger machine, or something more expensive, would be too risky. A Raspberry Pi is great and cheap but a bit fiddly.

Of course the 'computer' experience should be more diverse thant this, but having a dedicated machine feels like the equivalent of having book without distractions.

When I was a child I had a second-hand BBC Micro for distraction-free programming. We had a Mac for other fun stuff, but I kept coming back to the BBC. I'd love to be able to provide that experience.

The keyboard looks unsuitable for programming (even though it has the squishy lineage of the ZX Spectrum), but I'm very tempted.
> Perhaps if teens understood money better there wouldn't be such a huge problem with student loans. But there is, which indicates that they're not very good at managing money.

Students are going to take out student loans for as long as every adult they talk to before then extolls to them the limitless value of a college education.
This is horrible. Those photos are pure examples of architectural laziness. There were so many ways to integrate those facades in a real modern building - instead of keeping them outside as a pointless wall, prone to degradation.

At this point it would have been better to destroy everything.

Mixing old and new is an art... you need harmony between the two. And this harmony is missing in those pics. Perhaps in other countries they are better at it (italy? france? hungary?)
To summarize my point: It was a high-risk decision electing to do an instrument approach at LAX. I don't think the risks given by the Captain in attempting to divert were adequately weighed against the risks of going into the clouds (with such an emergency). I think electing to divert to a field with clear sky was the less risky choice.

Anyway, all's well that ends well.
The mismatch in floor heights is something I also find jarring. The changes in standards mean that floor heights are reducing, leading to this. It'd have cost them more to build matching floor heights and they might have had to have one storey less to get planning permission.

Something similar happened near where I lived in London. Developers got permission to build an apartment block on condition that it looked the same as its older neighbour. The result was an odd looking mini version, about 2 metres shorter than the original.

As far as I know, HLE is not implemented on AMD processors.

However, part of the fix for JCC (https://www.intel.com/content/dam/support/us/en/documents/pr... ) to recover the performance loss will make other CPUs slower if separate executables aren't used for unaffected CPUs... which they won't.

> The MCU prevents jump instructions from being cached in the Decoded ICache when the jump instructions cross a 32-byte boundary or when they end on a 32-byte boundary. In this context, Jump Instructionsinclude all jumptypes: conditional jump (Jcc), macro-fusedop-Jcc(where opis one ofcmp, test, add, sub, and, inc, ordec), direct unconditional jump, indirect jump, direct/indirect call, and return

The workaround to lower perf loss of having jumps uncached when they are on a 32-byte boundary involves adding quite some nops... (or padding with meaningless prefixes)

I just use a MacBook charger and usb-c cable, even if i don't have any apple devices.

The reason is that I move a lot and forget my chargers one or twice a year in a customer office, a hotel or at the airport.

The MacBook pro charger is very expensive, but charges everything I have and I can buy it pretty much everywhere, including at the last minute in an airport.

I dont know of his credentials as a scientist or mathematician to advance the field. But, he seems to be a ruthless optimizer, which can often leads to great leaps , even as a side effect. Neural networks are not difficult mathematically for any scientist to grasp really. And they are in actual need of compression and optimization. People are spoiled with general purpose tools that are not very efficient, even if computation is cheap.

That one at least keeps the houses looking similar. For a lot of the ones in the article I don't see how you are keeping thing aesthetically similar when you put a huge monster building behind the facade.
Preventing squatting is a fundamentally unsolved problem which I'm afraid can't be just "dealt with differently". If you want to allow anyone to own any domain and treat domain as personal property then squatting is actually unsolvable. Various possible measures necessarily limit freedom either by raising prices or quantity or property rights (i.e. transferability or usage). If you have any other ideas, please do let everyone know.
I don't know what Google pays for a Senior engineer, but from what I know about Amazon it's about 70-100k. Other companies that pay on this level:

- Zalando

- HERE Technologies

- N26

- Delivery Hero

- Soundcloud

- VW/Mercedes/Porsche backend startups (Proshare, Coup, Porsche Digital Lab)

And many smaller ones. From my circle, most Senior engineers earn in the 70-100k range total compensation. Since Berlin is still quite affordable, that allows a good standard of living.
When I think about the delays to Crossrail, I feel compelled to defend laziness, copy and pasting, and focus on cost-cutting.

It was originally scheduled to open in 2018[1] and is now not going to be finished until well into 2021. Why? A large part of that is the work they need to do in order to "manage to reuse the facade and fuse new and old into something that blends and flows together"[2]
