skysight-inc/HackerNews huggingface dataset:
I disagree. In the first paragraph she says 'in the first two weeks we have over-delivered on the impressions allocated for the entire campaign'. Varghese argues that the issue was not one of excess impressions, but promotional monies being used up without any impressions being delivered at all, ie to Kindle e-reader users who already had Discover cards as a default and got a $10 rebate for just using their e-reader as they normally would, without ever having been served an ad in the first place.

There's explicit discussion of new vs existing defaulted Discover cards in her request for data, and a request for information on 'how [Discover] will be made good', which would not be meaningful if they did not consider any funds misallocated. In fact that's mentioned twice, the second time saying that they will still 'need to be made whole'. You don't ask to be made whole unless you've suffered some sort of economic loss, such as not getting what you thought you'd paid for.

Of course we can't draw conclusions on the basis of cherry-picked emails, but this one does clearly suggest that Discover felt itself to have been short-changed in some fashion besides a lack of analytics information.

there is a reference to another promotion, "free holiday shipping", which very conceivably would be structured the same way

Conceivably, but not necessarily, and even if it was structured the same way that doesn't mean Discover should have had any expectation about it. If was was in the habit of ordering apple pie from you and one day added an additional order for pumpkin pie, I would not be happy just to receive an additional apple pie - not because I had lost my taste for it, but because of the failure to fulfill my order for something different.

The Amazon's subsequent email, cited by BI, notes that they resolved this visibility problem with Discover and they approved continuing the program within its original budget.

That is itself a bone of contention - Varghese is suggesting Paul Kotas shares responsibility with Munira Rahemtulla for the whole situation and helped her obfuscate the issue. So without endorsing Vargheve's position, that email could be entirely consistent with it.
Make sure never to commit to a public git repo either.

In all seriousness though, we're really bummed this happened and wish it hadn't. We do code reviews and try our best to prevent this kind of thing from happening. That said, if you truly want your account here to be anonymous, you're right to remove all personally identifiable information. I'd also recommend using tor (and using it correctly).

I've noticed really poor WiFi performance since upgrading to Yosemite, even when using tethering between two Macs both running 10.10. Ping between them is like 100ms... very weird. Also drops WiFi constantly on some access points.

Yes, please fix.
It's an optimization hack. By nature, they aren't that nice to look at.

`sym_equal` only makes 2 appearances in the whole codebase (to be bound to `Symbol#==` and `Symbol#===` in string.c), so there's not a whole lot of room for confusion.

Also, this is Ruby core! Smart people do what works and makes sense to them and don't spend a lot of time worrying about how clear it is to us unwashed masses.
It depends on how one has been educated.

A minimal fee (for example, 10c per bottle) is very advantageous, because people with higher salaries will just throw them not minding the minimal economic waste. People in the middle will return them while doing the grocery. Finally, poor people will hunt for them.

All of this, saves lots of garbage around.

As an occasional Reddit user, I find that particular feature rather confusing. If anyone wants to suggest a "native" way to do it on HN, i.e. that would fit with the existing design and be simple and intuitive, please email hn@ycombinator.com and we can talk about it offline.
I think the conflict is more cultural than people realize: an office in Daly City is tremendously easier to reach and if you're coming from South Bay -- essentially you exit the freeway and park.

On the other hand, getting to a point in SF from the freeway and parking usually takes at least 30 minutes (in addition to the 30+50 minute drive from the starting point in the South Bay or Peninsula). SOMA area is reachable by Caltrain, but Caltrain is unreliable, doesn't run as frequently nor is SOMA the only place where people have offices (and walking to further reaches of SOMA, or the area of Market, or FiDi is an often dangerous - especially at night - 20-30 minute walk).

Daly City is reachable from SF by BART, but that supposes you live near a BART station in SF and the Daly City office itself is close either the Daly City or Colma BART station. In general I'd say it's easier for an SF resident to get to certain parts of Daly City (those accessible by part or by San Mateo county buses running from SF are easy if you live near BART) than it is from someone in South Bay to get to SF. Driving is very easy if you live near 280/35/19th Avenue -- getting to Daly City from Mission especially is not particularly difficult).

That brings the cultural issue: different people prefer to live in SF vs. South Bay or Peninsula (some live in one place whereas they'd prefer to live elsewhere, of course). To hugely (but completely meaninglessly) over-generalize you can imagine the Peninsula as the OSI stack: physical and network layers are further south, middle-ware is in the Peninsula (Oracle in Redwood City), and presentation (end-user applications like AirBnb) are in SF (again, this is only loosely so: there are web app startups in South Bay and there are systems and middle-ware companies in SF). Intuitively it makes sense: I can't imagine starting a Foursquare in San Jose (there isn't a critical mass of people -- not all of them geeks -- cloistered around any given landmark to gain sufficient traction).

In many types of companies, you want both: which is why companies always seek to locate in either transit accessible parts of South Bay/Peninsula (Mountain View, Palo Alto, San Mateo downtown areas), run buses, locate in SoMa, or have multiple offices (this sounds like a "no-go" for Reddit, but Square, Google, Twitter, LinkedIn, and my own employer -- Cloudera -- all do this). Yet, if a company has a very strong SF-oriented identity (at least for its Bay Area office), a compromise location (especially if the compromise isn't just an SF office near 4th and King) could definitely upsetting existing employees who might also feel that they are no longer as valid as potential new employee the company wants to hire from South Bay.
PhotoTime – Smart Photo Organizer and Finder for Camera Roll and More
PhotoTime is the smart photo management app that automatically organizes, sorts and tags all your photos, including those from your camera roll and social networks, to make them fast and easy to search and find.

-------------
Why Love PhotoTime:

>> Search Your Photos
With PhotoTime, finding pictures of friends and other memories has never been easier. For each photo, the PhotoTime app automatically recognizes who, what, when and where each photo is taken, using image and facial recognition technology to instantly generate keyword tags. You can then use keywords to search your entire photo collection, regardless where the photos are stored, on the device and on connected social networks and cloud services to find every photo with that tag. Simply search for the name, event, location or other keyword desired and share the entire search result with friends—no more manually scrolling between albums and individually selecting each photo.

>> Tag Your Family & Friends
Built-in advanced facial recognition technology automatically groups faces that are thought to be the same person together for easy tagging. To search, you can simply type in the person’s name.

>> Bookmark Your Favorites
PhotoTime’s bookmarking feature takes the photo album as we know it to a whole new—and much smarter—level. To bookmark a group of photos, you can simply tap the bookmark icon and PhotoTime organizes these images around common keywords or keyword combinations. When new photos are taken, PhotoTime automatically recognizes the content, generates appropriate tags and adds the new photos to the corresponding bookmarks.

>> Customize Your Keywords
You can modify the keywords by adding or deleting the tags, to make them more personal and unique.

>> Your Photos Are Safe and Private
We take your privacy seriously. We will never store your images on our servers, duplicate them on your devices or provide them to any third party.

I'm sure McDonalds sold more hamburgers in the last 8 days than my local butcher sold steaks too. If HN would ever reach that degree of attrition it would be reddit.

> If you had 6kg of U-235 and through it forcefully on the ground it would most likely explode.

First, you mean "threw", not "through." And second, this is absolutely not true. To achieve an explosion you have to induce super-criticality with very precise timing. Otherwise the uranium will melt and become sub-critical before it explodes.

> This almost happened at Las Alamos

No, it didn't. You are almost certainly thinking of these incidents:

http://en.wikipedia.org/wiki/Demon_core

but those were completely different. It was a plutonium core, not uranium, and it went critical not because it was thrown forcefully to the floor, but because it was inadvertently enclosed in a neutron reflector that caused it to become critical.

Also I think we should stop making it a requirement of parole that the convict admit to the crime of which they have been convicted.

I certainly understand why parole boards have required these admissions. If someone has committed a crime but will take no responsibility for it, that certainly does not bode well for their future behavior.

The problem is that the justice system is not perfect, and occasionally convicts an innocent person. It's not right to demand that someone admit to a crime they actually didn't commit, and to deny them parole until they do.

Accordingly I submit that the only consideration for parole should be the convict's behavior while incarcerated.
I see a lot of negativity on this topic, but I for one am extremely excited about Alexis returning to Reddit in a more substantial way. I've been on Hacker New for a while (with different accounts) but have only recently started to use Reddit. Alexis is one of the most inspiring guys I've met ... lets just say I am a big fan. So, I'm really happy about this.
Level 4 isn't exactly a walk in the park; YubiCo have said their excuse is cost. They're listed as achieving Level 1 according to http://csrc.nist.gov/groups/STM/cmvp/documents/140-1/140val-...

Why are password hashes available via public API at all? Email addresses too?
My last company was the first place I've worked that moved offices while I was there, and we definitely experienced a 'weird feeling' and we lost a bunch of people. Everything just felt off after the move, even though things went smoothly, and our new space was objectively much nicer (upgraded from thoroughly class C space to a nice class A building).

I was trying to stick it out and wait for the culture and mood (which had been fantastic beforehand) to get back in the groove, but our best people started to leave one by one, then one of the founders of my current company reached out to me personally, and it was too hard to pass up.

As bad as data leaks are, it's at least nice to see one of these data leak stories where the passwords were actually stored correctly, instead of being MD5 / plaintext / base64.

Ellen Pao. Harvard Law, Harvard MBA, time at Cravath (very, very fancy law firm) and partner at Kleiner (which I imagine most of us know) is now to be the head of Reddit?

I am a firm believer that most media out there is not extracting enough value from their audience, or "under-monetizing", to use a ridiculous term. However, Reddit truly is different. I simply can't imagine someone with Ellen's professional upbringing will be the one who figures out how to retain the spirit, activity, and engagement of Reddit, while satisfying that 10x, $500mm valuation.

This ain't sexist, this is anti-elitist.Cutting and pasting monetization templates from other media properties, and building projected revenue models off of traffic numbers just can't work here. It's not Buzzfeed or Business Insider.

I was suspect when Erik Martin left (had the pleasure of meeting him in NYC, he lived and breathed what makes Reddit wonderful), and this really seems to solidify what I guess should've been pretty obvious.

I genuinely hope Ms. Pao holds things together, and the return of Alexis helps things out. The more I've learned, it seems Alexis was already gone by the time Reddit really took off and has been writing and speaking ever since. Curious how his operational prowess shows through the new chairmanship role.

Rant done. We're praying for you Reddit.

IMO, the problem is that your standard OS has way too much stuff running.

A SaaS app running in production should be about the size of your binary, and the libraries it uses. Instead, we have X, smtp, terminals and a full filesystem running. home directories and uids make no sense in an app that uses no unix users except for the one you're forced to use.

I'd really like to see a much smaller, simpler, non-posix OS for running server apps.

It took me a while to figure out what exactly you were objecting to, but I guess you don't like the fact that HN sends its data to Firebase?

I don't think it's fair to criticize the admins for that. For pretty much any web application you want to use, "only visible to you and us" should automatically be understood to include "and our hosting provider too, if they go digging or screw up."
I'm not sure how to make it more clear than I did, but this data was not intentionally shared with a third party. Had we known it would happen, we'd obviously have prevented it.

The only data we knowingly send to Firebase is already public and visible to anyone that can speak HTTP.

Sorry if I'm still talking past you.
