Cool concept. My main hesitation around using this product would be companies signing me up for coupons/spam via text messages. I can't imagine how annoying it would be to filter out text message spam...
What percentage of businesses have someone available to answer the telephone? This seems more convenient than that.

But it also seems like twitter.
> So what you have is various approaches to take advantage of special cases (different forms of GC), or approaches that give the compiler more information (as in C or C++, and Rust or Cyclone or MLKit).

Pretty much. I'd also add ParaSail to the list of languages that give the compiler more information (or more precisely, restricts what is possible, and for reasons other than just memory management).
For clarity, as I'm close to LIGO (but not in the collaboration) and found the title misleading:

A major upgrade of LIGO is almost complete. When it comes back online, if the detectors reach design sensitivity, it's sufficient to make detection of gravitational waves from neutron-star inspirals probable. As both LIGO and Virgo are down for upgrades, there's no chance of a major new detection from either until they're re-commissioned and running well (timescale of ~year+).

As reported at a workshop at the Institute for Nuclear Theory here at the University of Washington a few weeks ago, the Advanced LIGO upgrades have been going quite well; the riskiest work is coming toward a close.

The linked article makes no claims that there's anything new being dredged out of past science runs on initial/enhanced LIGO (which remains possible, if unlikely).
I think it's incredible what we can do with a medium like the Internet. It is a shame that so much intellectual capacity gets tied up in academic glory-seeking, and it's refreshing to see that the power of the connectivity of the Internet can let a lay person make stronger connections than a secretive academic.

Hopefully this and other stories like this will promote more active communication and sharing of ideas over silenced and competition for publication credit.
Well that my post wasn't nice is I think indisputable, but I wasn't saying that you're arrogant because you're French, just that the arrogance exhumed by your post reminds me of more often observed behaviour of your fellow countrymen. But let's not dwell on that - it would be silly of me to claim that something in the ink of your passports influences your behaviour.

I'm also not sure how I suggested you like social inequalities - if anything, I'm more inclined to think that you dislike them so much, that you deny their existence in cases where there obviously are. Apart from Catholic schools not costing 25k in Australia (I'm not even sure what the relevance of that is, but I know for a fact that the Catholic secondary school I went to a fundraiser for last year in Adelaide costs around 1000 AUD a year, and other Catholic schools in the greater Adelaide area cost the same; figures that are corroborated by the data I can find online for the rest of Australia). You seem to basically be denying that there is racism, or discrimination of muslims, in France? Are you serious? Because if that is what you're arguing, based on 'a vice principal was a muslim, so there is no discrimination', then I don't even know where to start in refuting you.

Your further argument is even more laughable and not only that, but plain wrong. You seem to be saying that the existence of words in a language indicates something intricate about the culture or society in which that language is used. That Inuit have 27 (or 30, or 50, or 100's) of words for the same thing is plain wrong, and the linguistic debate about what a 'word' means and how that relates to the Inuit language is not very relevant here (but you might want to start with http://en.wikipedia.org/wiki/Eskimo_words_for_snow and http://www.washingtonpost.com/national/health-science/there-... ). What is certain though is that the premise you derive from it, doesn't have merit.

So pray tell, what then makes your assertion of 'we don't have bullies because we don't have a word for it' more valid than e.g. my assertion 'the French are in denial about bullying because they don't even have a word for it'? (Apart from that I still don't agree with you on that point - there are plenty of ways French newspapers manage to express the concept every time another suicide because of bullying is in the news).

What enrages me most (well, not enrage, just annoys enough to spend 10 minutes to type this), is that instead of saying 'yeah maybe I kinda mis-expressed reality by making generalizations from what is probably a myopic point of observation', you basically make it even worse by saying 'not only do we not have bullying, we don't have racism or any other form of discrimination either'! In a country where millions are living in banlieues, and which has been officially sanctioned for the forced expulsion of Roma, just to name a few issues!

I attempted to create a similar service a few years back, but my concept was more targeted at users searching for local products and services, and not targeting a specific business. We would submit the user request to all matching local businesses. Maybe something to also consider, best of luck.
Thanks for the kind words and the nod, but I can assure you that there's still no shortages of excuses for late homework.

Since this is HN, I'll share one thing that works: force your students to use git (or some version control) for assignments.

Having an auditable history of effort makes it hard to lie.

Except when it turns "the dog ate my homework" into "git rebase ate my homework."
This would have nothing to do with the effect shown. Paid clicks (i.e. the number of actual clicks on ads) have been growing rapidly over the same time period. Dropping CPCs are pretty obviously a result of the mix shifting to mobile (particularly since both mobile and desktop CPCs are rising).
Nice presentation and solid idea. Initially I don't see the advantage over just directly calling the business. Traditional land line phones are loud, and are quickly answered. A messaging app can easily be silenced. If the user wasn't exactly sure what he/she needed I think speaking to someone is much more efficient than describing via a message.
I don't want to get into the politics, but I wonder about the algorithm the Wayback Machine uses to decide what to cache and if intel agencies manipulate it so the WM can be used for PR purposes.

"It is possible that the WM website could have been spoofed somehow to create these records, but it would not be easily done. To do so would either require hacking WM and creating the new records within its system, or spoofing the records by tricking WM into thinking it was accessing Girkin's page when it was actually accessing a third-party site. Both possibilities would be difficult to carry out."

Would it really be that hard?

Here's my take. I grew up in my parent's brick-and-mortar retail business: a four-store bicycle shop that's one of the largest and busiest in the nation. We were an early pioneer on the Internet, one of the very first to sell bicycle parts online back in 1995. These days, they don't do much e-commerce but brick-and-mortar business has grown a lot and the management is still tech-savvy.

Here are the problems that I see:

1. Employees are busy. In the bike shop, you're constantly running around, helping this customer and that customer, answering the phone, taking in a repair, doing a demo, etc. It's going to be very hard to get someone on a computer or iPad to do live chat. If an employee is typing on a computer within sight of a customer, the customer will assume that they aren't busy and will interrupt them with a question. The problem is so bad that when my father would go out onto the sales floor to fix a computer, he would put on a fake badge that said something like "DataTech Computer Repair Services" so customers wouldn't think he was a shop employee and interrupt him. Perhaps a speech-to-text interface might work but how is that better than a simple phone call?

2. Non-technical employees (most brick-and-mortar employees) are slow, inaccurate typists. Back when my parent's store was heavy into e-commerce, we quickly found that we needed dedicated guys to take online orders over the phone because most of our guys couldn't touch-type. If your interface requires a lot of typing, the employees and the customers using it aren't going to be happy.
I don't know who's downvoting you. I removed it, you were absolutely right and I let emotions grab hold.
I'm really not sure where I stand regarding limited availability vs. eventual consistency. But, I do know that I like that Orly aims between these two extremes.
It starts out with "By almost any measure, the world is better than it has ever been." sorry, that's just bullshit.

"Melinda and I are struck by how many people think the world is getting worse." Gee. Must be nice to be a billionaire.
This is what I meant further up thread when I mentioned segmenting the market. I don't believe everyone will move to a new solution but I do believe that some will. I also believe that the first users will be the technical ones who already understand the trade-offs and that there's a continuum of inconvenience that they'd be willing to endure (I'm lazy, so I won't tolerate much).

For example, think of the number of people who maintain their own static websites, either on GitHub or EC2 or elsewhere. All those people could just use Tumblr or Wordpress.com, yet they chose not to.
When I look at the clean logo used in the survey, I think more paperclip or 'A'. When this was announced on their blog, however, a hand-drawn image was displayed prominently -- an image which looks significantly more like a "butt" than the rendered version.

Love the presentation and as someone who prefers communications over text messages over a phone call, this has real potential if you can get businesses to respond in a timely manner.
answering the phone

That's what this is.
Very cool idea! I am not comfortable giving my phone number to anything that is not a non-corporate person, though. I can't see how you would need to have my phone number, so I'm ambiguous on how it would improve my experience. Everything you'd want to do with SMS could be done with push notifications, and it would be both faster, cheaper, and with higher fidelity.
Thought of a great analogy. Imagine it's the nineteenth century, and by whatever coincidence the dominant electric power delivery company actually also still owns a thriving kerosene delivery business, i.e. for lamp oil. They don't care if you run sewing machines or home appliances at the going rate for electricity - but every night after dark, they determine whether you're streaming electricity to power your light, and if so they intermittantly dim the power (to well below the level you're paying for), expressly to give you an awful experience and retard the adoption of electricity. Just so they can make more money selling lamp oil.

Net neutrality simply means they are not allowed to go into homes and figure out what you're using your electricity for, and try to charge you more based on that usage.
we won't need your phone number.
My favourite pigeon story would be that of Cher Ami: http://en.wikipedia.org/wiki/Cher_Ami
I was being pedantic. If you'd note elsewhere I explain to others the asymmetric nature of consumer ISPs, so I'm not obtuse to the issue. I just believe that saying untrue things is unhelpful to the problem. I want to be called out when I'm wrong; I hope others do to. I don't believe I was mean while doing so.

Also, nothing I said despite it being asymmetric, just that his point about pushing and pulling isn't the best way of describing the issue.
> ... unlike other major 20th century conflicts, it found the American people sitting on the sidelines

I'm sorry, but the American public has been sitting on the side lines for almost all of the 20th century's major conflicts. Hell, the Second Congo War (1998-2003) was the 3rd biggest conflict in the 20th century and it was barely reported on. That conflict alone killed some 5 million people. Apathy towards war is northing new.
Although NAC is an anti-oxidant, the benefit in CF is thought to be from the ability of NAC to break down thick mucus. CF results in thick lung secretions that can't be expelled, which leads to lung infections and lung damage.

NAC has a free thiol group (R-SH), which can break dithiol bonds (RS-SR) in mucus to help thin it out.
You know, there's just so much. I've been at it four years and I still feel like a damn newbie.

Gotta know your linux, your scripting, vagrant, docker, salt, git, testing, continuous integration, editor(evil + emacs in my case), algorithms, datastructures, best practices, libraries you are currently using, sql, how servers work, how the web works, memory management, and on and on and on.

On top of that, synthesize all of the above into something usable and maintainable, then maintain it. I'm starting to suspect the day I have a good grasp of the basics is the day I become a master.

In strict CAP terms, eventual concurrency is a form of limited availability, but it's a special enough case that I think it deserves separate consideration.
I wonder if Verizon's customers could form a class action lawsuit accusing it of failing in good faith to deliver bandwidth from Netflix due to intentionally congested handover points.
Have you reached out to NORD (National Organization for Rare Diseases)? They don't have a website for connecting patients with rare diseases, but they are a pretty well run organization that help connect people the old fashion way.
The video demo is fine. Text is phone these days and answering a text is exactly the same as answering a phone call asking for more info. A 20 yo retail associate at American Apparel will take to this and figure this out in an hour.
Guess we should update the landing page to show more. Thanks
> That passes any reasonable grounds for denying an RTBF request.

That passes your definition of reasonable grounds.

The problem is that there doesn't exist an established "reasonable grounds" in this area, period. There is no legal test as to what is "reasonable." It's left up to the likes of Google to decide what records society keeps on who. And that's absolutely flabberghasting.

Within a month of this "right" being instated, evil people were already using it to cover their tracks, and that's a Fact that cannot be ignored.
Do they use different backbones? Which side of the business runs the interconnects?

I think your characterization of drug companies is unfair.

There are a lot of things that make it tough for drug companies to provide drug for compassionate use (before FDA approval). Often early on manufacturing hasn't been developed enough to make large quantities of drug. If they give drug to everyone who asks for it, they won't have enough to run their trials. What is the impact of that?

The implementation would be the same thing as this company. I don't understand how it's different.

100% of retail business don't have this this either.
There's obviously a lot of specifics around contribution of mobile to these numbers, and what impact has come from enhanced campaigns causing advertisers to bid on mobile even if they were not intending to.

That said, as an experienced paid search professional, lower CPCs are good for me if overall quality remains the same or improves because it lowers my acquisition costs and improves my ROI. This in turn causes me to spend more with Google.

Beyond that though is the notion that while CPCs may come down, Google has been pushing hard on the retargeting front. There has been a lot done to try to educate advertisers about the notion of multiple touch points and cross-channel attribution. With this comes paying for net more clicks since additional touch points may increase the conversion rate significantly, and thus might warrant paying for multiple clicks.

They still have a ways to go IMHO...for starters, why the heck isn't display data baked into some sort of search funnel-esque report? And why can't I see revenue associated with view-through conversions? AdWords has the data if conversion tracking is setup...

Closing the display loop and enabling advertisers to see the actual INCREMENTAL contribution of display impressions and view through conversions is critical to this IMHO.
"The vast majority of programmers lack the knowledge, skill, or both required to correctly implement anything."

Agreed.
I know that we need to support old programs that expect these behaviours of these device nodes. However, how about a workaround like "udev only creates /dev/urandom once /dev/random has been seeded"?
It would only have to accept it with TCP. I could do an equivalent thing with UDP and just send data anywhere I want. (Remember the poster said the internet and not HTTP.)

Also, that has nothing to do with the point that "pushing isn't a thing on the internet" is a poor way of describing the problem being described, especially since the poster said the internet and not consumer's using their ISP (which still isn't strictly true, but is at least closer to the idea of the asymmetry in most consumer and business interent connections).

That doesn't negate the point that consumers download much more data than they upload.

When I say something incorrect, I expect to be corrected. I attempted to correct something that was factually wrong and don't believe I was mean while doing so.
Banking systems use limited availability rather than tolerate inconsistency. Banks are pessimistic.

Mixpanel is looking for a lead operations engineer
Hey HN -

Our engineering team of 12 is currently handling 50K requests per second, 500+ servers, and over 20 billion data points per month.

We're looking for someone to come in and take over the ops load - and hopefully eventually lead a team of operations engineers.

Many of our biggest problems are around infrastructure and scale, and there aren't a lot of startups where you get to work on this stuff.

If you're interested, please drop us a line - jobs@mixpanel.com.

-----

Operations Engineers at Mixpanel are primarily focused on reliability, automation, and physical infrastructure.

In this role you will:

* Diagnose and fix problems with physical hardware and/or software
* Automate tasks such as server configuration and deployment
* Build and maintain monitoring and alerting infrastructure

Our engineering culture:

* We do very thorough, line-by-line code reviews using GitHub pull requests. This keeps our code quality high and helps us learn.
* We try to have two people work together on every project (collaborating, not pairing). It's more fun and it results in better code.
* We practice rapid iteration. If it's better than live, we ship. We also build things so they can go live (whitelisted) long before launch day.
* We write tests for things that are mission-critical, prone to failure, or cause paranoia. Think billing and datastore code, not Django views.
* We care about learning. Right now we're reading through Advanced Programming in the Unix Environment.
* We currently have 9 vim users, 2 IntelliJ, and 1 emacs holdout.

What we are looking for:

* At least 5 years experience as an Operations Engineer or equivalent
* Experience running 100+ servers (preferably physical rather than virtual) either as the sole Operations Engineer or as a technical leader in a team. You should be the person that people ask for help when they can't solve an operations problem.
* Fluency in python or the ability to learn it quickly. You should be comfortable writing code daily.
* Strong problem solving ability. You should be able to start with a symptom and methodically work through the problem until you find a root cause.
* Solid understanding of TCP/IP networking. You should know how and when to use tools like tcpdump, netstat, ethtool, etc.
* Extensive experience with Linux, especially debugging and performance analysis.
* US work authorization

Why join Mixpanel?

* We are profitable, with millions in monthly revenue and over 2,200 paying customers.
* Mixpanel is still a small company, but we are poised for great growth.
* Our product is used by companies like amazon.com, Dropbox, Intuit, OpenTable, and Salesforce.
* We've raised money from top-tier investors: Andreessen Horowitz, Sequoia, and Y Combinator.
* There are a lot of cool people here. You will like the people you work with.

Want to join?

What's the hardest operations problem you've ever diagnosed and solved? Explain it in your cover letter in as much detail as you would like.

Mixpanel is an equal opportunity/affirmative action employer supporting workforce diversity.

A sexy command line interface musicbox for geek
I'd put PH into a 7th bucket: This will never be a big business, but it's a useful tool for other YC companies and we just made a deal to get preferential treatment.

Ironically YC (or at least PG) emphasizes how they want to back companies with a chance of becoming >$1B businesses. It's somewhat sad to see this violated in such obvious ways. Ryan is a talented guy and I've been reading his stuff way before he started working on PH. I'm sure he'll find a way to turn this into a nice business, maybe even pivot to something that has a much larger market size.

However, I agree with the overall sentiment of this thread. PH is a tool from SV insiders to SV insiders, sending exactly the wrong message of what types of products people applying to YC should be working on.
Autopsy of LeBron James: Lessons Learned About Greatness
This seems to be a specific case of the more general principle of "concentration of measure". Terence Tao at [1] has some useful notes. From a quick scan of the paper at http://arxiv.org/pdf/1402.0423v1.pdf, Theorem 1 seems to essentially be a CoM result for the order statistics of symmetric RVs.

This same principle can be applied in other contexts [2] - e.g. Johnson-Lindestrauss is essentially a statement that random projections are "often" nearly isometries.
