This proxying actually rolled out on December 3rd to most gmail.com users. We, Streak, happenned to launch an email tracking feature on the same day (http://www.streak.com/email-tracking-in-gmail).

Here's what we've learned:

- the proxying of requests only happens when a user is viewing the mail inside Gmail (i.e. gmail does not actually affect the message body, its just proxying at render time)

- gmail only caches in the image for a few minutes. So for email marketers, if your recipient views the email then views it again a few hours later, the marketer will see two requests for the image

- there is basically no personally identifiable information in the request that Google's proxy sends to the server hosting the image. So from that perspective this is actually a boost in privacy than the previous state of the world. None of the headers, cache controls, cookies, ip addresses, referrers or user agents are passed to the original image server

- obviously you can encode some ID into the image URL itself but all that lets you do is identify the email address of the user that opened the email. But you already had their email address because you sent them an email - so again, no PII gets disclosed

- it is true that marketers will see a more accurate count of opens (because displaying images is on by default)

- there seems to be several ways to get gmail's proxy to NOT cache the image and simply proxy the request every time the user opens the emails

A friend of mine is an electrician. He did his apprenticeship with a guy who worked a lot with high end residential clients (i.e. stately homes — this was in England). He says the one of the most important things that he learned was to clean up after himself — which talks to your respectful point. It made him stand out amongst his peers, and is one of the factors that goes a long way towards repeat business and referrals.
Sure! It's amazing work, but with the electric needs of the cabin I just think it might have been almost too high a quality of power (assuming the source isn't subject to drought and deep freezes aren't a problem). The cabin looked like it was in a clearing, so I think he could have put in something like http://www.wholesalesolar.com/solarpowersystems/workshop-3-o... (9kW) for a similar price.

edit: please take this in the context of my first comment. I think he should be taking care of more of his thermal needs with non-electric sources, neither solar nor hydro. Also, nobody's load is continuous, and real life load correlates with daylight hours. Anyway, I'll stop, it's a really cool project and don't want to take anything away from it.
This project, its description, and this guy's whole website[0], is awesome and inspiring. This man seems to have working practical knowledge of electronics, hydro-engineering, welding, can make his own transformers, has a sense of humor, etc. Impressive guy!

That's the same in EU - amazon.co.uk shows 1-3 months delivery for R9 280X and in Poland the arrival date of new batch was already moved twice in the last 3 weeks.
3 weeks ago I placed an order fo R9 280X, the LTC difficulty is now 2x of what it was then. I think I will soon be cancelling the order as LTC price falls and the break even point is ca. 2 months instead of 1 month.
I've experienced this first-hand on more than one occasion when I was a game developer at EA. Production consistently rewarded fire-fighters without realizing they were in fact encouraging arson (though fires were always through incompetence and not intentional gaming of the system as far as I know).

If the people who put out fires consistently get the best rewards, don't be surprised when a lot of things catch on fire.

The challenge is that you want to reward the most skilled people. However, "skill" isn't easily visible to some managers. Instead, they observe that:

effort = difficulty / skill

They can't measure skill directly, so they note the above and try to solve for it. But that only works if you can measure difficulty. That's no easier to measure than skill. The mistake they make (as in the post here) is that they just assume difficulty is a constant.

If you're going to use effort as a metric for skill, you must have a measure of the intrinsic difficulty of the task. If you can't directly measure your employees' skill or the difficulty of the tasks you've given them, you've got real problems.

I would have thought so too. But when I applied with a floor of $160K, a lot of the responses I got claimed they don't pay that high. Then I was quite floored when a friend of mine who works in the area told me to ask for $135K. Also, how much does technology matter as long it's mainstream?

I'm not the GP poster, but I'd suggest that one of the few policy areas the Tories and Lib Dems found that they could readily agree on was civil liberties.

One of the first things the new government did was start the wheels turning on what became the Protection of Freedoms Act 2012. Whether you think that law went far enough or not, I suspect most here would say it took steps in the right direction on numerous issues where the previous New Labour administration had eroded rights and liberties. A few of them were big-headline, fundamental issues, but there were quite a few relatively minor concerns addressed as well, such as the excessive use of surveillance by local authorities that we're talking about here.

Given that coalition government is not the norm in the UK, I suspect politically it was more important that this was something the two parties could agree on as an anchor than anything else, though no doubt many of the incoming Lib Dem MPs and at least some of the Tories were no fans of the previous situation anyway.

A well-written and researched piece. Two snippets:

'She will bring a tub of blueberries to a meeting and just stare at you, popping blueberries into her mouth. People feel so dismissed.”

Great way to unnerve your peers! And here's what, I think, to be a very accurate assessment of the Find the Lady game (shy nerd, powerful woman, company savior) that Mayer perfected:

"Another [...] thinks that Mayer figured out very early on that being a female engineer—a rarity in a culture that reveres engineers—gave her a pass that other women without that credential would never have. After all, her flaws, like her habit of being late, are easily fixable—should she care to fix them. “This idea that she is shy and just a quiet engineer is such fucking bullshit!” the executive says. “She is savvy about knowing that it makes her Teflon.” '
I don't think it relies on any strong version of EM, just about comparative speeds of different information channels. The market's reaction could be wrong, but anyone likely to make big moves likely knew before you.

Seriously. I see more and more posts like this on HN. Someone uses a word or phrase in a sentence that is a tiny fraction of the actual content of their post, and someone replies with paragraphs (with references!) about why that phrase or word is not something they would choose based on something completely unrelated. Instantly derailing and detracting from discussing the actual points made. We need to start downvoting these kinds of posts.
Correct me if I'm talking directly from my rear end:

For that scenario, Google could ignore the arguments and just request the file. However, I'm not sure I get Google's implementation of the proxy, but if the images are grabbed only when the email is read, it's easy to track by adding a hash to the filename itself.

So, in the email company's server, they'd have a canonical file, for instance, acme-co/dec2013news/img53.jpg. For each subscriber, they'd have something like a symbolic link to img53.jpg specific to the subscriber, for instance img53-5baa61e4c9b93f3f0682250b6cf8331b7ee68fd8.jpg.

EDIT: Checked a newsletter's source and that's what they already do. Since I don't deal with email marketing much, I honestly had no idea.

I'm very wary of hearing you made $xyz of revenue.

My current company (multi-million dollar telco) is continually chasing revenue, and it's driving us into the ground. We recently did a $4 million dollar expansion to our cable infrastructure to accommodate a new little community, involving many kilometers of fiber, a few expensive switches, etc, etc. After all of that, we got less than 20 customers paying ~$100/mo. The expected break-even for this project? Over 200 years.

The kicker? The people in charge got raises and promotions because they netted the company more revenue.

Ask HN: What are your biggest challenges in regards to growing your business?
I have a passion for growing startups. I’m relatively new to this, but I’ve been all over learning (and doing) a lot of growth strategies.

I’m not a growth hacker, but I do love the concept. However, I would not limit growing a business to repeatable, measurable strategies.

Some marketing cannot be measured, optimized nor predicted, and I also emphasize partnerships, whether it be with other companies, deals w/ people who have an audience, etc.

I’m looking to help companies grow, and I have a few business ideas in mind, but I need to do some customer development.

Now that I explained my background, and used about 10 different buzzwords, comment away! Let’s see if I can help...
I've been thinking about this a lot. It would be awesome if someone wrote some sort of guide for identifying markets with large demand and little competition. Like you say, once you find such a market, everything else falls into place. Indeed, at that point there is probably not much you can do wrong.

I appreciated the lack of pictures of large penises that accompanied spam. And of course the fact that you didn't get a tracking pixel fetched. So I wonder if they are going to fetch the image from their servers, cache it, and then show it. Cutting off a supply of information for email marketers, whom they will offer to supply 'opening' information for people who use the new Gmail Promotions feature. (ok that is a lot cynical)
Agreed. The bitcoin ecosystem will need traditional banks, credit cards, and the rest of the financial services industry. Prices that involve transfers will just be lower, and interest rates on deposits will have to factor in expected deflation once that stabilizes.

A "giant filter" over google news still does not cut at the root. I think the problem is the perverse use of this medium (i.e. computer-web system). It is a medium that is not sufficiently understood by most, or perhaps any person yet. From reading (Englebart, et al) it seems this medium would be best used as a tool for collaboration.

Unfortunately most people (including myself) don't deeply reflect on a new medium/technology, to figure how best to yield it to amplify human intelligence (or make human progress).

I argue "cutting cord" for news via TV and the web may be the best thing to do now until more is understood of its affects on humans. People don't realize that it is the medium that is the problem and there is no amount of "filter" that will help them and they suffer unnecessarily.

One reason is that AMD has a single-instruction bit rotate, which is used a lot in the hash function. Nvidia needs three instructions.

Another is that AMD uses a large number of simple cores, and Nvidia has a smaller number of more complicated cores. The simple cores are all the hash function needs, so AMD can run more operations at once.

Do you know of any good write-ups on buying LTC? I know there are plenty out there for BTC, but they don't always translate well to LTC
We already get the gist here. It has become imperative that we consciously strive to add "humanism" to our practices: human-centric this, human-readable that... Many of us have to be reminded to be nice — and there's a positive trend between circumstantial ethics and hours spent in front of the computer.

Non-technologists fear that technologists have lost their humanity, and thus incur an air of arrogance. That's the point here.

Most of them do not want (1) welfare from the tech hierarchy, and some of them do not want to participate in this arbitrary hierarchy (2) because of their aesthetic views on technology overall or (3) because of their lack of education regarding the subject.

Probably by talking to him. It's not hard to tell if a manager has no clue about what you do.

If he doesn't, then he's probably using some silly and lazy metric like "hours in the office" or "lines of code written per day". If he does, he probably took the time to learn about your job and make a more accurate assesment of your work.

Really, as a programmer you are supposed to know lots of things, learn some more and work hard; but the guy above you cannot be bothered to learn some useful skills in order to asses your work? What kind of logic is that?
