It's definitely a neat demonstration that he can produce a collision for these favourable "neutral-bit" IV's relatively cheaply.

I suppose the next steps are to find two inputs that produce favourable IV's, then repeat this process for those, and that seems like it's getting really close. Stevens actually already has the best near-collision in non-reduced SHA-1 I know about from this paper:

http://marc-stevens.nl/research/papers/EC13-S.pdf

I made a quick visualization of it here, it looks pretty cool:

I also added the Shappening vectors:

https://lock.cmpxchg8b.com/shatter/visualize.html?shappening...

It's funny that they actually collide around R74, then he has to diverge again so that when you add the IV (part of the process of creating the IV for the next block) they collide.

I moved to Seattle in 1980 and fell in love with the city and it's unique culture. Seattle has grown up for sure but in my view the growth has been handled overall pretty well and we have kept a lot of the coolest part of the culture here(music, beer, coffee, movies check out the SFF, outdoor festivals every weekend during the summer, great outdoors, the sea and mountains and so on). I have been tempted many times by offers from the Bay area and the valley but I still love this place and just can't bring myself to leave, although my second love is SF :) In a lot of ways I see Seattle and San Fran as sister cities.

The term "gun control" is thrown around without definition, which makes it difficult to have an intelligent discussion.

Let's start with the assumption it is impossible to alter the constitution to remove or severely cripple the second amendment, which, I think, is a reasonable assumption.

How, specifically, would you define "gun control"?

I'm talking about Hackernews. I go on it minimum ten times a day, my colleagues too, my friends developers too.. but we are obliged to install an app on our phone to access it correctly.

Is there a reason for that?
A bit of a tangent to this post, but within the walls of NASA there are a few projects which are trying to structure themselves around the startup tech company model. The CAS (convergent aeronautics solutions) project is one example.

Source? Because the Census Bureau also releases the Supplemental Poverty Measure [1], which amongst other breakdowns includes numbers that adjusts for taxes (if you're going to count for tax credits, you also need to account for taxes paid if the numbers are to make sense), housing benefits, and various in-kind benefits. It also includes various other costs. Table 4a on page 9 gives a breakdown on how different aspects of the Supplemental Poverty Measure affects the total number.

The lowest version you can get from that table is 11.8% - if you remove medical out of pocket expenses from the income subtractions before calculating the rate (in other words: if you assume people are perfectly healthy, directly contradicted by evidence, you get a more favourable number of how many people can afford to put food on the table).

I'm curious what elements you'd add/remove to the SPM to get to "nearly zero".

I like it already. I typed in some words related to my startup and it proposed some really good prompts I could turn into articles. Other content-generation sites have given terrible results and suggestions, usually in a Buzzfeed style "6 things you'll never guess about art!".

This site I could take a few of these and go write a few paragraphs about off-the-cuff. Looking forward to playing more when the site comes back up.

I think the data would be more interesting if it was presented as a stacked bar plot or a set of pie charts.

ed: also the fact that you do way fewer experiments; isn't that mostly because you moved from neuroscience to retail? I don't know what neuroscientists in industry do, but I'm assuming they'd have to spend plenty of time in experiments too, is that right? Or do they just hire a bunch of minions to do the dirty work?

Back around the turn of the century, I used BrokerageAmerica, which not only had $0 trades but gave rebates on your trades. They made their money as a market maker. Eventually, they dropped the rebates, then they dropped the $0 trades, then they dropped themselves (selling off their accounts to Ameritrade).

Which is to say, they aren't the first $0 brokerage and they won't be the last $0 brokerage. But I don't expect them to be around long term and I double don't expect them to provide $0 trades long term.

It's sufficiently radical that I think it would be worth going to (civil) war over. It's an predicate to imposing anarcho-tyranny, where people and areas that don't, for example, vote "correctly" have their police protection largely withdrawn. This has happened in the U.K. and D.C. in recent memory.

It's also hard to see how this would make the police any more accountable to the people.

Very cool. I'm not an AMZN or AWS fanboy, but this is really neat stuff, and very impressive how much they continue to increase their market lead.
For starters, I'd like to

* index every piece of data properly, for easy reference to (a) films, (b) user ratings (per user per film) and (c) users (seeing the latter as simply sets of ratings on films)

* then run a few collaborative recommendation algorithms on the indexed dataset - basically taking things from the scikit-learn python package and running them

* then see (naively and heuristically) whether any recommendations for myself and for a friend who's interested in this make sense

* then do a more proper machine learning dataset split into "teaching dataset" vs. "testing dataset", to see if any of those algos can predict what films a particular user would be interested in watching and how much they'd like them

* and then to move onto something which may (I think) provide insights for this particular dataset, such as e.g. attempting to classify users into clusters, to see if there are any more homogeneous clusters of users, with some users acting as connecting "bridges" between clusters; I'd start with the kNN algorithm here, for example

* it would also be interesting to attempt to classify films as well, and see whether some curious non-intuitive/non-stereotypical clusters emerge (something beyond well-known genre categories, etc.) I'm not sure what I'd be looking at in particular, but basically this assumes that we really do trust the collective ratings of users. The latter may be very problematic - for starters, I'm quite sure it'd be difficult to attempt to "normalize" the different ways users vote (4/5 rating is one thing for one person and another for a different person - of course collective averages may help here, and that's one of the things with this MUBI community in particular that drew my initial attention: overall (subjectively and with bias) it seems that the overall community rates films quite responsibly and with a degree of (let's say) signal.)

* visualize classified clusters, include sliders which alter parameters for classification (including kNN's simple "n", but beyond that, too), etc.

Introduction to problems and classification of distributed systems
These signs piss me off every time I see them. Always make me think "Oh, I know, it's so horrible that we're helping to bring fresh life into your local economy, with new amenities and attractions". Sure, high paying tech jobs certainly contribute to housing crunches, but they also help solve them by making high-density buildings with affordable housing in them possible. The street goes both ways.
While I first heard "fuck the police" in the context of rap, it certainly doesn't seem to be a non-mainstream concept anymore. All of the people I know that feel that way are, as far as I know, law-abiding citizens. They've seen first-hand the ways that our local police have treated them (or neighbors) poorly, and have nearly zero trust that they would be treated fairly in any encounter with the police. They've arrived at that philosophical stance after seeing misbehaving officers protected by their departments, or "on leave" instead of fired or prosecuted.

After seeing and reading about various types of (local and national) police misconduct, not to mention the fact that police have asserted that it's __not__ their job to protect us, it's hard not to feel that their perspective is somewhat reasonable.
I recently moved to the eastside and haven't been experiencing much disdain for being a tech worker. Most of my spare time is spent heading into the cascades to hike the amazing trails, though.
"In 1973 for example, the Environmental Protection Agency noted that Volkswagen sold around 25,000 cars with temperature-sensing switches that were used to deactivate the emissions control system. Specifically, Volkswagen’s Fastback and Squareback 1973 models would sense low temperatures and cut out the cars' exhaust recirculation system."

Wait, what?! I'm now definitely not convinced of their "it was all the Engineers fault, we didn't even know" argument.
On that note, I was surprised to learn that if all you do is apply some invertible transform to the IV (xor with a constant, swap words, whatever) before processing the last padded block in Merkle-Damgard, you get an indifferentiable hash.

Can't wait to launch one of these.
GPG can use SHA-2, but the way that GPG signing works in Git is that you essentially GPG-sign the SHA-1 hash of a Git object. So even if GPG is using SHA-2 for its signature, it's no protection against a collision in one of the underlying Git object IDs.

Edit: this is only true of tag signing - with commit signing you GPG-sign the whole commit object.
But that's what I mean, fair enough if the screen was too small and kickstand fiddley on the SP2, but the SP3 fixed that completely. But then the goalposts shifted...

And they definitely aren't abandoning this philosophy seeing as they announced the SP4 at the same event. The Surface Book is a competitor to the Macbook Pro, but they aren't slowly creating a Macbook Pro. My sense is that Apple are now slowly moving in this direction.
Fantasy land != Reality

There is no such thing as shooting to disable. You always aim for center of mass and if you do not feel threatened enough to shoot to kill then you shouldn't be shooting at all.

Now the caveat to this is if you shot an intruder and they're still alive, but now injured to the degree where you can safely disarm them and keep a gun drawn on them; current U.S law makes this a problem. You can get in legal trouble/sued by someone who broke into your home with a weapon intent on killing you, but only if they live.

This means not only are you shooting to kill - you're now dumping an entire magazine into the person to make sure they are dead.

E:

To the people who downvoted, how would you disarm an intruder with a gun? Ask them politely to put the weapon down? Run at them with a baseball bat (and risk getting shot)?

Or maybe shoot them in the arm or leg? Where major arteries are and the shot is still likely to be fatal and also has a higher chance of missing entirely.

Life isn't Call of Duty and shots to the legs/arm don't just "injure", they kill. So I'll repeat myself: there is no such thing as shooting to disarm or disable in real life. Only in fantasy first-person-shooter land.
> The payments — to support both Cruz and Fiorina — have added to the air of mystery around Mercer. Is he motivated purely by conservative ideology? Or is there something more, such as translating his big-data expertise into campaigning? Cruz is building an aggressive voter targeting operation, bringing in a pro-Republican company specializing in personality profiling that has been paid millions by Mercer-backed political committees.

He supports the Club for Growth, NRA, American Crossroads, and GOP Congressional candidates and has since he became wealthy.

Of course, this is one reason why I'm not in politics.

Interesting that this trend is present in the works of many artists from the post communist block , not just photographers.
You will notice this trend in music, film, literature, painting, even comedy.

The depiction of decay, of ruin, of wet cold abandon (ex: http://micleusanu.blogspot.com/).

Foreigners might find these trends in arts a bit strange and dark, but for us it is the way life has been and probably will be.

This is also felt in the mentality of people - the future is uncertain and all our efforts to build a better society (life for ourselves) in the future may end up the same as before - decay and abandon.

Looking at all the new incredible buildings recently built in places like Dubai, Emirates, China and so on, I can't help but remember these ruins of the once mighty empire of the people for the people, wondering - how will they look 100 years from now ?
Regarding your second point, I really understand this position - fair enough (re. zeitgeist and personal point in life of someone looking for films and rating films, etc.) I just wonder if it wouldn't be interesting to spend some time looking at recommendation systems which are not just simply about intersecting users' votes and presenting something "just what you've recently liked." But this would be more of a playful experimentation which is more hobbyist in nature, for sure.

As a current NASA engineer, I suspect that the truth is along these lines.

It's also ridiculous that these same people benefit greatly from a growing economy that's directly influenced by (and these days also partially propped up by) the boom in tech while deriding it like it's some kind of negative force. It sounds to me a lot more like envy than any nostalgia for artistry and run-down neighborhoods, as they claim.
It's better to not make any laws because someone might break them.
