It seems like you're comparing current conversion rates vs. past conversion rates.. Did you try AB testing this side by side? It's not necessarily only the effect of image optimisation, could be just organic growth of your site?
It really does! At twice the sampling rate it's pretty interesting, too.

Copywriting tips: how to be effective
>You should get out daily, for at least 1 hour. Simply because that one hour is for recharging your brain, which again leads to better performance.

This has been pivotal for me when I work from home. I like to go out for breakfast to start the day off and then go out again in the afternoon to run some kind of small errand.
Meaningful names would be nice.

In C++ iterating over a map items you get a pair with ->first() and ->second() methods instead of key / value.

Python has named tuples which can work both ways.
Linus once introduced Tanenbaum on stage when he was the keynote speaker at Linux.conf.au 2007.
I've read in multiple places about Amazon's main pricing strategy, which isn't all that different from what Walmart employs. They pick specific brands/models/categories of product at which they will absolutely be the cheapest. Everything else is just regularly priced. So if you follow a 'non-standard' product for them you would probably find that it probably is about the same price everywhere else- with one exception: there have been bot-price setting wars by different sellers that have escalated the prices of arbitrary products to insane levels. This is where you see the $200k toothbrush or $1m used book.

I do the most of my shopping at Amazom because I can build up my basket through the week/month and just do one order without leaving my house. Price checks to different retailers in my area find that usually Amazon is slightly less or exactly the same price and I don't have to spend hours going to the retail store. Finally, I can get it all in one place instead of going to Target, Home Depot, and wherever else.
Correct me if I'm wrong...but shouldn't you also include the time you spent in your "final cost"? For example, if my time is worth $100 per hour and I spend 10 hours, sure, my debit card shows that I spent $100...but add in my time and now it's around $1100. I could have used that time to work on other things, to generate even more value for my startup, and effectively break even when the company I hired to create an explainer video delivers.
They key is to save madly and prepare for the downturns. One of my friends in SF bought his house in 2011 for 500k. The comps in the area 5 years later are 1.2-1.4m

He was prepared (waited 10 years).

You can do it, you just have to look at the past as a guide and when opportunities arise, strike. Also don't be afraid of leverage. Good luck :-)

drive work hard

Agreed. It is precisely because I found myself on a trundling career that had little in the way of prospects after graduation (and that job I found by literally showing up on doorsteps and being a general pain in the ass), no hope of ever owning property in London, being stuck in a squalid flatshare, and having nothing to lose that I gave it all up (not that there was much to give up), started a company, lived in a squat, and a decade on employ 50 people and own (well, the bank owns me) the roof over my head.

What was it Baldwin said? "The most dangerous creation in the world, in any society, is the man with nothing to lose."

This world is currently producing vast numbers of young people with nothing to lose. Some despair, others start businesses, others start criminal enterprises or join IS.

While there's something to be said for the motivation that the total absence of prospects can grant, it's a generally crappy situation which would better be served by reducing wealth inequality. Dare I say "Universal Income".
Quilts are a ton of skilled work, but they're beautiful when finished.
My mom made the quilt pictured below for my brother out of more than 25
years of annual shirts from a particular Aikido camp.

Of course, I doubt my mom would be too keen on making me a quilt with
the "Bianca's Smut Shack" shirt shown on Jason's site, and I doubt any
protests from me about it being "a part of web history" would win.

EDIT: Failed to spell Aikido properly, again.

For a moment, I thought they had added true multiple value return to C++. I am sooo glad they didn't. The lisp folks added it way back, and it has been an ugly scar on the language ever since. Why do real multi-value returns suck? because they don't compose well, they're awkward as all heck to use, and require wrapping certain function calls in really weird constructs. The PROPER way to do multiple values is to return a data structure and pattern match against it. Of course, lisp has support for this, multi-value return was just an optimization hack. WHICH YOU SHOULD NO LONGER USE!
the aws smallest instance comes at 450$/mo (about 300/mo paid upfront), the one he suggest comes at 200$/mo but the gpu seems cheaper. still one would need some sort of payout to keep it running, it's not exactly cheap and you need to shell 2k upfront
I received an email suggestion yesterday of a variant of this command that places it inside a function, so that you could play multiple instruments at once with function calls. I guess you could make an entire music composing utility in bash if you wanted to.

"We just have to stop them from voting themselves legislation to compensate."

It's become clear that the UK government (no matter which of the two parties are in power) will do whatever it takes to allow the young to take on enough debt to fund ever-increasing house prices. I genuinely expect to see some kind of scheme that either explicitly gives these people the money their house "should" be worth, or in some way tilts the field so that they make it up in other ways.

On the plus side, my shares in house builders have done really well, and some of them have got so much money they don't know what to do with it; big dividends and occasional special dividend payments ahoy.

How so? I mean being an unmarried couple isn't cheaper than being a married couple.

At least among everybody I know, the reason for delaying marriage is that marriage isn't seen as that important any more, especially before kids show up in the picture.

The only argument I could see is that falling median household income is the reason people are delaying having kids, which then makes getting married early less important.
I've definitely been asked by potential clients if they can look at my LinkedIn profile to get an idea of my background and the sort of companies and projects I've worked on in the past (and I've even had clients ask that about other members of my team too).

One site that seems most nimble right now would probably be indeed. They are growing a lot particularly here in europe and are more flexible in their partnering agreements. I work at the moment for a SaaS recruiting product, and I know all the big players are a pain to work with for integrations.. just reams of red tape.

Another thing that is far more common in europe is that the job sites are much more fragmented. There are so many craigslist type sites that are driving lots of traffic that recruiters want to integrate with.
You are right. If I added in my normal consulting rate, the cost would have been the same as the original quotes I got. But for me, I valued the learning experience of doing something I had never done before. To be honest, it was a good change from the core development work on the app, or the social media marketing I had been doing.

I am pretty much a one man show here, so am used to doing everything myself now. In a sense, I still think that the added skills I am learning adds value to my startup. Once I started earning serious income and hire others, then I will have to strive to become better at delegating work that is not my core speciality, but until then, I just have fun learning. :)
This! Especially with the web being increasingly consumed on low-powered mobile devices.

It's also not just about being faster than the network because the browser is probably simultaneously doing page layout, javascript parsing, image decompression and a ton of other things. Also more time spent decoding images is a drain on the battery.

Focusing solely on compression stats can be misleading, it's a balancing act. For example, I'm not sure being 0.7x smaller than PNG is much of a win if FLIF ends up being an order of magnitude slower. Perhaps it is still a win but it needs a bit more nuance in the analysis to reach that conclusion.

The MRF loss is patch based, and adapted from CNNMRF [1]. Since the precursors to PatchMatch (as mentioned in the PatchMatch paper) were MRF + belief propagation based, I am pretty sure it could be done with some tweaking.

These analogies seem quite similar to the "user constraints" PatchMatch allows to be set, though an explicit "be straight" constraint might be much more difficult to optimize.

It's nationalised insurance. They don't need to mislead you to convince you there is a value in the service they provide. Since it's government the information is public.

I used to sell chairs online, and this particular vendor had an extremely high suggested retail price. I couldn't find anywhere that actually sold it for that price. I don't think it's aspirational like the article suggests, I think it's to help all of the distributors. If the mfg can change a number and help everyone downstream increase sales, that's a windfall for them.

That's why it's always important to compare prices. Start at Google not Amazon :)

You may be right. I haven't gone and read the standard yet, but I also fed related programs to cbmc 4.9, a C-program verifier, using the -bounds-check flag. It tags x[0][3] as an out-of-bounds access, but not f = &x[0][0]; f[3]; (also (x[0]+i) is OK according to cbmc, despite what we all learned about (a+b) and a[b] being the same!)

Neither variant is picked up as illegal at runtime by -fsanitize=address and gcc-4.9 or clang-3.5.

I'm personally not going to A/B test larger webpage downloads for my customers.

Smaller is better & faster. There's no noticeable difference in image quality.

So my A/B test is 4 months before vs. 4 months after. This is not a small sample size. It's around 500k uniques on each end. 3M+ page views on each end.

I've also broken & analyzed the traffic down by channel, new vs return, and any other way I can to attempt to remove any false positives. From all the data, the large increase in conversion was because of this particular change.

I have been aware of "holiday shopping bias" around nov / dec, but January is normally a very shitty month for conversions. January / Feb our conversion was higher than any previous month before this as well.

This is actually why I've waited to Feb to really solidify the results in my own mind. And that's why there's 4 months of data to back it up. Every day since the change, being better than before.

I don't need to A/B test this one. The savings on my homepage was 4MB. We're not talking small bytes here. This is a major issue with regards to anyone using Shopify.

See if you can guess which month the change happened on this chart:

Do any of these newer/experimental schemes, such as this one, take into account other factors such as CPU load before declaring themselves as "better". For example this project seems pretty cool, but there's no data on how CPU bound, memory bound, I/O bound its decompression algorithm is.

I guess what I'm asking is, if I hit a web page with 20 images @ 100k per image is it going to nail one or more cores at 100% and drain the battery on my portable device. Fantastic compression is great but what are the trade offs?
Photography is a reflex – Steve Bloom
This depends on implementation (unrolled RNNs vs true recurrence). Each minibatch needs to be the same length, but that is it. And that is even implementation dependent - if your core RNN had a special symbol for "EOS" it could always handle it in another way.

Normally you pad each minibatch to the same length (length of the longest sequence in that minibatch), then carry around an additional mask to zero out any "unnecessary" results from padding for the shorter sequences.

The BiRNN (using all hidden states) + attention mechanism is the thing that allows variable length context to be fed to the generative decode RNN. A regular RNN (using all hidden states) + attention, or even just the last hidden state of an RNN can all be used to map variable length to fixed length sequences in order to condition the output generator.

You will note that padding to the length of the longest sequence in a minibatch wastes computation - people often sort and shuffle the input so that sequences of approximately the same length are used in each minibatch, to maximize computation. If you padded to the overall longest sequence (rather than per minibatch), you would pay a massive overhead computationally.
"Scaling infinitely" is a pretty steep requirement. I wouldn't go there yet, either implementation of the blockchain technology is useful long before the insane transactions per seconds which VISA is handling.

But yes, Ethereum has similar constraints as Bitcoin. Vitalik did some scalability blog posts on https://blog.ethereum.org/ but it's entirely possible that any blockchain technology just won't scale as we would like it to (that is, as good as a centralized approach).

OTOH, if there is a good technological solution, currently I have much more confidence that it gets implemented in Ethereum than in Bitcoin. The current infighting, bickering and actual threats and actions (e.g. DDOS at dissenting miners) is slowly but steadily destroying the Bitcoin community.
You might have already considered it, but as a potential user I'd like to have the chance of adjusting the percentages at each billing period (month for example) to avoid rewarding sites that use tricks to increase page count or other metrics.

By default, percentages go to each visited site as determined automatically by your service.

I'd also like to veto certain publishers, to avoid giving them money when landing there from obscured redirections or by accident.

Of course, if I veto a site then I would not get privileged access to it. That's fine.

That might be at odds with your three-party verification scheme; this is just a suggestion in case it might be useful.
What amazes me is that this process can be totally automated and made invisible to the user.

Alas, nobody wants to invest the day or so in actually writing the methods to do it.
