As an expert in both the umbrella of methods known as compressed sensing and more recently deep learning, my opinion is that these techniques are largely complementary. Deep learning is fantastic at for instance building appearance models and exploiting hierarchical nature of natural images, and hierarchical feature building in general where appropriate, while methods from compressed sensing remain as quite useful general methods via which one can efficiently extract low dimensional structure, from noisy and at times even highly corrupted datasets.

It is true that deep learning is now state of the art in certain tasks such as super-resolution for natural images, which were previously the domain of linear inverse problems, and this is due to its ability to learn useful natural image priors, something that isn't possible with simpler linear or slightly non-linear models. Meanwhile, compressed sensing style methods still excel in situations where the data does not benefit from hierarchical compression, labeled data is not available and/or the data is highly corrupted. Take for example the Netflix challenge problem, discussed in the video, for which deep learning is unlikely to offer substantial benefits, at least for the problem as stated (we just observe partial information about movie ratings). Where deep learning could potentially help in that situation is for instance grouping movies according to high level semantic information derived from text descriptions, other metadata and even the video content of the films themselves, which are still somewhat open problems and would not necessarily add value, depending on the validity of the low rank assumption of movie preferences.

More recently studied problems such as phase retrieval, which are in a sense the most elementary non-linear inverse problems, have now been understood, and in fact have informed understanding of how information propagates in deep neural networks (http://yann.lecun.com/exdb/publis/pdf/bruna-icml-14.pdf). More generally, the study of favorable outcomes in non-convex optimization, which is informed by recent developments in the umbrella field of compressed sensing, will help drive understanding of what makes training deep neural networks possible and thus to improve it, with the current empirical performance of deep learning being far ahead of any theoretical understanding.

Broadly speaking, as opposed to fighting about the relevance of one field or the other, we should strive to achieve better overall results by using both sets of techniques complementarily.

For an annual fee somewhere between $500 and $1500 you can sign up for concierge primary care via a network like MDVip.com. I signed up my mother last year when she encountered some health issues and didn't feel like her primary care doctor had time to work with her and formulate an appropriate treatment plan. No fault of his - I found out later that he has a panel of almost 3,000 patients. Her new MD has less than 500 patients and will spend an hour per visit with her, is reachable via cell phone nearly 24/7, and will often check in pro-actively to see how she is doing. The difference is night and day, much more comparable to the experience you describe in Brazil. And for less than $1000/year I consider it an absolute bargain.

As I read the report I notice a lot of PostgreSQL "backup" systems depend on snapshotting from the FS & Rsync. This may work for database write logs, but it certainly will corrupt live git repositories that use local file system locking guarantees. NFS also requires special attention (a symlink lock) as writes can be acknowledged concurrently for byte offsets unless NFSv4 locking & compatible storage software is used.

Ask HN: Datacenter server discovery
I am looking good solutions on how to discover new servers from different vendors that get racked in the datacenter for 1st time. The current process we use for dell servers is the following.

We have a discovery server in the datacenter that has multiple virtual interfaces to different management networks. One of them is on the same network as drac default ip.

We do an arp ping to discover all the macs of the different dracs and then connect to each of them and configure the servers to pxe boot. The servers boot a pxe image and record hw config of the server into a database.

This allows discovery of new servers and servers that have had their dracs reset to factory defaults when they get moved from one dc to another.

This gets quite complicated over time having to manage all these different virtual interfaces in multiple datacenters. It requires a dedicated discover box that has a cable into the management network making it a single point of failure.

How do you discover new servers after they are racked that is efficient, reduced manual entry and allows you to track which rack they are in.

If you have an env that discovers servers purely through pxe boot without touching the management interface, how do you account for servers that fail to pxeboot or fails to load your discovery image or some other failure at scale.
This sounds like an insanely bad idea.

> than that their products are actually popular

A minor quibble here. No argument that they're popular. What surprises me is why they would be more popular than ever, after a year with so much bad press.

At the same time, they have recently had a couple quarters where they were down year-over-year, so there is definitely incentive.

As to whether they would ever deceive investors... Apple is usually more ethical than your average company, but they have had lapses in judgement before (eg: just google for Apple and "backdating", "antipoaching", "EU consumer law"), so I don't rule anything out.

That said, I have a little regret posting that comment, since it's pure speculation, possibly tinfoil-hat territory.

HN moderation isn't particularly connected to developments like YC funding the ACLU. I add 'particularly' because maybe there's some weak action at a distance that none of us are conscious of, but it's nothing like the close correspondence your comment suggests.

Aside from the health and economic benefits, the other major benefit worh noting is environmental.

In Europe I find it really hard to watch people _constantly_ throwing cigarette butts down storm water drains, into canals and doing other disgusting things, like stubbing the butts into the sand on the beach or into the soil of a river bank. I find it highly disturbing how un-aware people are about the damage being done to fragile eco-systems.

I remember walking around Rome not long ago just thinking how disgustingly dirty the city was (I love Rome btw), there was little flower gardens just over flowing with butts, butts accumulating in gutters etc.

I actually felt anxiety about it raining just knowing where it was all headed.

So yeah, it would be cool to see this happen in other places around the world.

> It also doesn't work when anyone can freely migrate between the states. You can't have large social assistance programs and high taxes in one state and the opposite in an adjacent state and not expect an unsustainable influx of low income people into the state with more benefits and high income people and businesses into the state with lower taxes.

> The problem with the federal government is that it's structurally too susceptible to special interests. Instead of an exception-free flat tax and a UBI that nobody can cheat, you get a tax code full of deductions for donors and a welfare system full of subsidies for industries with strong lobbies like insurance and finance. Instead of a normal-sized military that defends the country, you have a corrupt money train into the military industrial complex.

> Probably the only fix for it is to put the important bits in the constitution, e.g. there shall be a flat value added tax the rate to be set by Congress, Congress may provide a universal basic income to every citizen in the same cash amount, no other federal taxes or federal social assistance shall exist, military spending in peacetime is capped at 5% of GDP (where "peacetime" means "no enemy soldiers on US soil"). Remove as much discretion and complexity from the federal government as possible, and if something isn't suited to be done simply and uniformly then the states have to do it.

Yes, the way fiscal/monetary policy is built would need changes but I think it can be figured out. I think you hit on the "solution" I had in mind to a large degree.

When I made that comment what I envision is basically this:

A) A progressive federal tax system that funds the LEO, Military, Justice, and International obligations (i.e. Embassies, foreign policy) without deductions or much chance of modification via a constitutional amendment that no state is going to willingly override. (i.e. The tax rate will be progressive, be based on multiples of the median household income, and will not allow for deductions beyond a standard deduction of all income below the poverty line. In peacetime, there is a % cap of GDP for the tax rates outside of covering the cost of the poverty line UBI.)

B) The social safety net has to be built into that ultimate amendment as well. Yes, some people will try to cheat...but the government can just reduce payments if they do so fraud shouldn't be worse than unemployment now. (i.e. A UBI for the unemployed equal to the poverty line without trying to gauge the "why" of unemployment.)

C) A state of War requires the consent of 50%+1 of State governors to release the funding cap on the Federal government (as a check against the Federal government just "deciding" terrorists are enemy soldiers on US soil or other loopholes).

D) The Federal Government only intercedes in forms of regulation as a mediator between states or if the constitution is violated.

E) The basic structure of the Federal government otherwise remains the same.
InsideSales CEO – No true AI in the market and data scientists aren't a thing
You shouldn't let yourself get to that point. Your alerting system should alert you when disk is at 70% or something with a ton of margin. If it's not set up that way, go stop what you're doing and fix that. (Seriously.) If you're running your systems so they usually run at 90% disk usage, go give them more disk (or rotate logs sooner).

And even assuming all that fails and I'm in that situation where I have seconds until the disk hits 100%, I would much rather the service crashes than make a mistake and delete something critical.

If someone is breathing over your shoulder, you can even enlist them to co-pilot what you're doing. Even if they're not technical enough to understand, talking at them what you're about to do will help you spot mistakes.

As a complete guess, something like using sessions persisted back to the PostgreSQL database, without something like memcached in front of it.

With that kind of approach it could be trying to update a session table (with new IP address?) for literally every page load by the 47,000 people. Which would probably suck. ;)
It's a pity you're being downvoted, because your first paragraph is factually correct. I guess people don't want to hear it if it conflicts with their (mistaken) preconceptions.
Maybe a physicist can tell me why I'm wrong here:

We often visualize the effect of mass on spacetime by using a trampoline and a bowling ball. The outer edges are flat and the closer you get to the bowling ball the more spacetime is warped downward.

On the outer edges, the effect is almost nonexistent and the trampoline's surface is nearly flat. What this suggests is that spacetime without mass is flat and that mass warps spacetime in a downward direction. So no mass = flat, mass = curved downward. So the effect is in the range of [0, black hole].

Obviously this is an very loose analogy but bear with me.

What if spacetime acts more like a waterbed? Not only does mass warp spacetime "downward" but something (in our analogy the displaced water) pushes the rest of spacetime upward.

To use a signal processing analogy, a filter will (nearly?) always affect the passband to some degree, with very high Q filters creating a knee where amplitude is increased significantly before the filter rolls off. That seems counterintuitive (at least to me) but it's nonetheless true.

Using another analogy, curved spacetime creates regions of "downhill-ness". What if the space between masses get a little bit of uphill curve as well? That could explain e.g., the Pioneer anomaly and possibly at much larger scales the effect in the article.

> Effectively, Trump hijacked the Republican Party.

The Republican Party was hijacked by globalists a long time ago. G.H.W. Bush probably was very influential after Ronald Reagan was shot (1981?). Bill Clinton continued GHWB's globalization programs. G.W. Bush was mostly a figurehead. Like Clinton before him, Mr. Obama continued the globalization program, and transformed the globalists' boots-on-the-ground imperial war machine into a kinder, gentler aerial bombardment regime-changing machine.

Señor Trump wasn't supposed to win. The hysteria exhibited by some in response to Señor Trump's opening moves [1] is certainly engineered by those whose globalization programs are now on the executioners' block.

I think the point the OP was making (correct me if I am wrong) is that the banning of political discussion may have been a bad idea as it was obvious that this was going to happen.

The leading Republican candidate has been constantly talking about these types of bans yet discussion on HN was not allowed during a time where perhaps discussion could have prevented Trump gaining power.

Now we are in "cure" mode. It would have been better to prevent this from taking place.
