Can someone (espescially with a finance mindset) explain the valuations we are seeing?

Slack has 1.5 million users. Assuming average yearly revenue of $100 per user that's $150 million in gross revenue. A 9 billion valuation would mean 60X revenue!

If you compare it to Dropbox, their last valuation was $10 billion and their rev rate is supposed to hit $1 billion this year. So why are Dropbox and Slack valued similarly when Dropbox makes 7x the revenue? I get that growth rate impacts your multiple, but not to this extent.

I actually think Slack is a cool company and can have a sustainable business. However, what I'm missing is that a lot of valley companies have valuations that are completely outside their fundamentals (revenue, growth rate, margins, etc.). In this category of "great companies but overvalued" are Snapchat, Slack, Uber.

I would expect a 10-20x multiple on slack since they are high growth. So a valuation of 1.5 - 3 billion would make sense. What am I missing here?
I think in practice most of the market don't care about using 30+ year old lenses. And if your using manual only lenses, you have many options on which body you want to use.
FB had $10.2bn net income in 2016 on $27.6bn revenue. How can it drop back to its $100bn IPO valuation?
Beer is usually cheap, yes. However for wine and spirits you have to go to the SAQ, where some products have really bad pricing.
They need to lobby the state to take away the city and county governments power to derail construction with bullshit zoning and permitting. If someone wants to build 45 story high rises in sunset district, why should SF stop it.
I don't think that is cynical at all. Such an incentive structure + the general public's lack of interest in the human rights of prisoners, would guarantee that outcome.
Interesting. I was thinking of cans when I replied so that's presumably a big factor.
Round avatars look like shit if you haven't planned for it. A lot of big names now have to redesign their twitter photo.

Is it really a problem to emulate this in software, though (honest question)?

As far as I can see, if compability with old software is the only concern, then losing 80% performance isn't really a problem since the new CPU is probably 5x faster anyway. Thus making up for the loss, so the old executable runs as fast on a new CPU, using emulation, as it did running in hardware on the old one.

So all we'd really lose is a speedup for legacy software -- and who really needs to play Wolfenstein 3D at 80,000 FPS, as long as it works?
Even with caching it's quite poor, especially if you are using frameworks that aren’t written to properly take into account its unique means of execution (which the vast majority do not).
The amount of roaming you get depends on your carrier and contract. We get up to 20 GB of roaming or your contract data cap, whichever is lowest. E.g. me and my wife can roam for 20 GB because our contract is for 24 GB, but if we had a 12 or 6 GB plan we could only get 12 or 6 respectively.

I think the word you're looking for is "hatred".
Instagram is not just a camera app anymore. It’s strong point is distribution and discovery. There is a huge pro photography community on there. They all shoot with serious DSLR/Mirrorless setups, edit shots in Adobe Lightroom and then post the resulting photos on Instagram for their following to see and engage with. Do not dismiss the pro use case for Instagram because it is massive.
I'm thinking Slack's issue is their free version is too good and the paid version is way too expensive (per user pricing gets scary) I know in my experience we don't have any trouble using free and we have too many people to make a jump to the paid. I think Slack needs a "middle ground" solution where small-medium businesses won't balk at the per user pricing.
Linux was never ported to 16- or 8-bit hardware but through the magic of Turing completeness and emulation somebody did actually manage to get an 8-bit micro-controller: http://dmitry.gr/index.php?r=05.Projects&proj=07.%20Linux%20...

(Yes, this is so convoluted, and so unusable, that it basically reinforces, rather than refutes, your point.)
Is it?

Perhaps part of the issue is the fact that companies like Google/Apple/FB use tax loopholes so their HQ cities don't really have the funds to properly manage the problems these companies create with their large employee base.
WhatsApp didn't fade at all. They have 1.2 billion monthly active users and climbing. Their "stories" feature got 177 million daily active users in just 10 weeks. For comparison, Snapchat is only at 166 million DAU as of Q1 this year.
US slavery was ended. Women got the vote. Segregation was ended. Gay marriage arrived. Eventually and painfully in many cases, but things do change.
I don't have an English-speaking article handy, but female deer in the Bohemian Forest are still walking up to where barbed wire was during the Cold War, and turn around.

They have learned that they couldn't get further and have imprinted that "knowledge" to their offspring.
They really need to just eliminate all local power and consolidate all zoning decisions with a single housing czar. It's clear that democratic solutions have failed.

Why didn't he test by age? Age is likely the variable most linked to salary. Older developers didn't use fancy IDEs- just a simple text editor is all you really need.

Buy a copy of the book "Starting Strength" and hit the gym each morning. The early results will boost your self esteem and getting to the gym is an easy 'win' on days when you're struggling with your career.

Right now you're number one risk is falling into a melancholy funk. Strength training will help avoid that.
If the USG was aware of a secret flaw in RSA, they wouldn't be tipping their hands about it to random small companies. Come on.

But: avoid RSA anyways. It's inferior to modern curve crypto.
I mean yeah. Money laundering is just tax evasion and fraud with illegally gotten money. We treat it differently than regular tax evasion because it's a more serious crime, much like how pre-meditated homicide is treated differently than regular homicide. Does that make sense?
Most articles don't have someone calling them bullshit.

Upvotes on an article don't mean endorsement of all the claims.
You really don't see the difference between the phrases "worst country ever" and "not particularly nice"?

You're going to have a hard time both learning and teaching if you can't reign in your language a little. No one around you is actually understanding you because your language doesn't represent your true thoughts. You are the only person hearing the arguments you think you're having.
I also disagree with their idea.

I think we should just change the purpose of prison to one and only one thing: Reform. Leave justice out of it, and the rest will follow
Yeah, same here.

For me there's a giant difference between code that lasts, which needs to be sustainable, and disposable code, which doesn't. I'm also very big on YAGNI; my code gets so much cleaner and more maintainable when I'm only solving problems that are at hand or reasonably close. Speculative building for the future can get insanely expensive: there are many possible futures, but we only end up living in one.

Indeed, I think a "do it right" tendency can prevent people from really doing it right. If we invest in the wrong sorts of rightness up front, we can create code bases that are too heavy or rigid to meet the inevitable changes. So then people are forced into different sorts of wrongness, working around the old architecture rather than cleaning it up.
They're $100 on Amazon and $80 at B&H. $100 looks like the normal street price for them.

What is the point of expecting people to be bilingual? Is it not more efficient to standardize on one language?

As someone with a P50, I've been really really impressed with it, even though 64GB has been pretty overkill. I just wish I could have gotten it with a 4k screen instead of just HD.
This is the problem with allowing the government to have invasive surveillance powers - they use them not only to prevent legitimate threats but also to try to prevent the social changes that naturally should occur over time.
Snap sinks to its IPO price
Except for the extreme dryness, the mandatory change of shoes at the office (and getting there except if it's near a metro station)
Sure, but that destructive power has nothing to do with online communications. I sort of buy your argument about the power grid, but I am absolutely confident that a dozen motivated and funded people from this forum could easily build our own darknet, operating over some combination of radio waves, dark fiber, and sneakernet, that is completely invisible and unknown to law enforcement.

Again, there have been conspiracies (and armies) in human history for centuries, and most of them didn't have realtime messages in people's pockets. They had letters carried on horseback, and it worked just fine.

People use encrypted chat apps over the internet because it happens to be easy enough and reliably secure enough. If it weren't, there's no inherent reason to keep using the internet for this. There's enough other ways to communicate.
Once you get permanent citizenship, yes. However that takes a couple of years to obtain, and meanwhile there are pretty severe requirements.

(I know a few people who have immigrated but I have no direct experience with specific policies)
You have other people on call to care for critical infrastructure.
The difference is that one could reasonably write a C compiler in assembly, and use that to bootstrap a better C compiler if desired.

Writing a rust compiler in assembly might be challenging.

Because they made boatloads of profit from charging their customers for roaming.
"innovative ways to address the housing crisis..."

So the bar for innovation has now been lowered to include fancy trailer parks and the resurrection of the 'company town'?
Most successful application I've worked on have either already been around for 10 years, or have lived onto become 10 years old. The ones that didn't, were usually not successful.

It's a good reason to be careful to avoid the latest and greatest, but go for tech that has (some) track record of being maintained and used for a few years.
Then could we make a small change to the incentive structure such that this becomes a non-issue?

For instance, could the government pay out the fee over 10 or 20 years (perhaps paying it in full on release), and stop future payments if the prisoner dies while in custody?
I am Norwegian, so I thought I'd add a few points, which I think greatly influence the difference.

1) Prison guard education is just a few weeks in the US to my knowledge. In Norway it is a 3 year college education, where you learn about mental illness, why people become criminals, how to rehabilitate people etc. The prison guard job in Norway, is by American standards more like a social worker. Guards spend a lot of time doing activities with inmates. They are not simply there hit misbehaving inmates.

2) The criminal justice system is largely under professional control. We don't elect sheriffs, judges etc like in the US. So there is less opportunity for populist "though on crime" politics to win through. Policies are mainly driven by professionals in the field.

3) Norwegian culture isn't as hung up on good and evil as American culture. I guess that is partly because religion has little importance in Norway. Christianity is quite focused on the idea of good and evil. Norse mythology was never like that. There was no evil devil. The world was divided into order and chaos not good and evil. The world "evil" almost never surface in any discussion. It isn't just the justice system, but Norwegians themselves aren't very interested in revenge. E.g. I've never heard a single survivor from the Utøya massacre express a desire for revenge.

I don't know why it is like that, but perhaps a reason is that Viking culture was very revenge and honor based. But this mentality was destroying society so authorities worked hard for hundreds of years to change this mentality.
Data Scale 2017 Recap
Non-linear effects can be seen when measuring THD. Any non-linearity will distort the sound and create additional frequencies in the output.
There are a couple of orders of magnitudes more Intel 8051 derivatives out there than there will ever be AVRs, and they still have yearly sales in the 100s of millions.
Trying to isolate one factor and saying "That explains everything!" is bad thinking.

Is this what they're doing, though? Seems to me their conclusion is that frequency response doesn't explain price.
Probably in an old desk somewhere, it wasn't an NSL but I wish I would have held onto it, I would have captured it on my phone if smart phones were around then. It basically said if you are going to keep using PGP or custom encryption for the app that they would like to meet with us to discuss since we were connecting to government financial endpoints. Then it said if we use RSA that this would not be a needed discussion. It was very strange and eerie all in all and we did not want to rock the boat.

Since we were small/medium agency/company we just complied as we were just helping smaller/medium companies sell stuff like Ukuleles and hats to AAFES so it was not a big issue. The key of the app was the EDI/AS2 integration that didn't use the PGP or custom crypto as it had to use certain algos RSA/DSA/TripleDES/FIPS/strong hashing for Drummond Group interoperability certification. The certification of interoperability and crypto communication was required to trade with Wal-mart, govt/AAFES etc.
IMO, that reads just as well. Each object is still indented, it's close enough.
Read for content.

I wasn't talking measuring 0-60 time in cars. I was talking about measuring steady 60mph. No one does that, because it's useless (although it would be easy to measure). 0-60 time would correlate somewhat to impulse response in audio, which is a useful measurement, and much more rarely seen.

I'm reminded of an experimental example a professor showed us in my college audio recording class. He hooked a square wave generator up to both analog tape and digital recorders, and recorded the square wave. Then he played back both sources on an oscilloscope. The tape had a sharp lead spike followed by a shrinkage on the tail of the square, from compression. The digital recording had a rippled top, from frequency-related distortion. Both were inaccurate, but they were inaccurate in very different ways.
Let's sum up the available options:

1) update rarely, fix a lot of breakage at a time
2) update daily, run into each breakage as soon as it happens and fix it
3) never update, no need to fix anything

Did I miss anything? Just saying 2) is what works for me. Takes 1-2 minutes every morning before I start working (updates to all systems have been checked and downloaded overnight).
Preauthorize the card or use whatever strategies that Kickstarter uses. Wouldn't be a problem for $10 payments in the same way it would be for freelance contracts.

Version 2.0 would hook payment up to a successful pass of the test hook!
> Pavel Durov wants everyone to think security is about trust in people

I think his point is the reverse, while people trust Signal because of Moxie & Trevp.

puts Tinfoil hat it's possible that Trevp is not "that" involved with Signal because he doesn't want to be involved with the government and backdoors.
Then your editor / layout engine has to be smart enough to distinguish between Dr. Smith and the end of a sentence.
It helps to acknowledge the fact that you are constantly dying from something. Everyone's time is finite, and there's very little benefit in chasing the tail of the "If only I'd known about X" dragon, because there will always eventually be an X you don't know about that gets you.

(... at least until we perfect the longevity treatments ;) ).
Or perhaps the cities and state of California killed their whole tax base by restricting their property taxes through Proposition 12 and artificially reduced the supply of housing through regulation and zoning.

Companies like Google have been using tax loopholes every where in the world, but the only cities facing housing crisis tend to be the ones that have reduced their supply of housing through regulation.
City planning is not done well in SF. But it is a real thing. And it can be done well.
Coming from a signal processing background, this is interesting. Would your company be interested in doing a newsletter with https://enterprisedeeplearning.github.io?

Edit: softened the sales pitch
It's a totally different game now.

I do a lot of tiny Arduino programs for hire. Before you go off on me, I'm an experienced embedded developer -- my current project is taking a digital input and turning it into a resolver signal for a motion controller. Fun!

The simplicity of the Arduino ecosystem means that a rank beginner can throw together a simple program that provides huge value in just a few minutes . They don't need to know the intricacies of setting up an A/D channel: they just call analogRead() and it's done. These people don't want or need to be programmers. They have a simple task to automate and they found a way to automate it and move on with life.

I have a client that I've written two simple programs for that are essentially latches: take a transient input signal and hold an output constant forever when it's received. But it's faster/cheaper to throw an Arduino at the problem than go wire up a handful of 'LS74 latches and associated hardware.

Your argument is akin to complaining that no one drives stick shift any more because automatics are too popular.
To some extent, solitary confinement is way, way worse than death sentence. It is burying people alive. It's a miracle a person can survive for so long and walk out of it in one piece. I imagine the psychological scars must be pretty profound...
> Telegram stores the messages you send/receive unencrypted on their servers.

Anyone who has used Telegram for more than 5 minutes knows there are secret chats. The effort being made to rig the information against Telegram also tells a lot about its relevance.

Why do you trust the OP's claims? How about all the people disagreeing with the OP?

However, people on social welfare in Spain hardly can afford a cheap... (ok not sun) holidays in UK and Ireland.

I got some faith too. While the US has a very strong conservative base who supports backwards policies. Liberals are quite strong as well. I think the main issue is that liberalism in the US until Bernie Sanders, seemed to care little about economic equality, which lays at the heart of almost all other social problems.
They are built good enough. My whole point is that Beats will never make an audiophile happy, but normal people love them because they sound good (enough), look good, and are comfortable. Plus you can get them for a few hundred dollars - an amount that most people can come up with.

It's not that different than watches. Some people will spend thousands of dollars on a mechanical watch with fewer features and less accuracy than a cheap watch you can buy at a gas station. But the mechanical watch works well enough and it looks nice.
The most important thing you can do today to prevent pancreatic cancer is.... believe it or not, don't smoke. Smoking causes somewhere around 30% or so cases of pancreatic cancers.
That's annual, so ~$8/user/mo.
Yes, that would seem to be nonsense, the general estimate you see floated around is that the manufacture of an IC engine vehicle generates emissions equal to those from its operation[1]. Clearly the battery pack in an EV / (P)HEV will also create some, but it seems unlikely to be as large a delta as all that.

Precisely. It's that "metastatic before symptoms appear" part that gets you.

Pancreatic cancer doesn't generally compromise the pancreas before it metastasizes and compromises something else. That's the worst thing about that one; the first self-identifiable symptom is usually "My stomach is upset (because this thing has already grown past the borders of the pancreas and is now playing general hell with the abdominal cavity)."
$100,000 for the location is very very cheap — I think that's the key. You could easily build out for $100k in most of the country, but you're not centrally located.

You literally can not own anything for $100k in the top 5-10 cities.
Mountain View doesn't have the funds to permit more housing? My understanding is they give permits for new offices no problem, so I'd like to know where that point of view comes from.
The only reason 2, 4 or 8 is less "readable" to anyone is because they have a mental breakdown when they see a style they don't prefer and can't get past it. Tab is a variable width character, it has no place in text laid out with fixed-width fonts.
Came here to respond with something similar to the first paragraph. I was wondering if perhaps audio engineers mean something different when they're talking about impulse response, since my expertise is in signal processing for electromagnetic signals (vs. audio).

My apologies, I didn't read your comment as an implicit criticism, and surely didn't intend to come across as if I did.
