Wal-mart has expected vendors to bow to its methods and policies for years, no matter how unreasonable or inconvenient. The carrot dangled in front of vendors: The possibility of massive nationwide sales.

Now they are dealing with a much more nimble and capable competitor. Yes, Amazon has its own unreasonable policies that squeeze vendors, but at least they have reasonable tech in place and they move fast when it comes to support and service. Case in point: Applying to be a third-party seller on Amazon takes days, Wal-mart Marketplace takes 6 weeks.

I am not sure if this latest Walmart policy reflects incompetence, misguided policy, dirty tricks, or a combination of the three, but it serves to push vendors away from Walmart and into Amazon's tight embrace.
I got that advice from some talk about refactoring in OOP languages, as far as I can remember Manager and Calculator were the discussed bad class name examples, "what do you manage/calculate?". Explicitly naming things you operate on was part of the advice given in the talk.
aws does not have access to that data, so it does not make sense. walmart are trusting third party with that data, but are somehow afraid that amazon would break in its own system to look at your data, something that would kill aws. i dont think that data is of that value, if it where it would be inhouse.
You're letting personal feelings about Walmart get in the way of rational thought.

Remember: If not them, Amazon certainly would have done the same.
It is to my knowledge that the problems have been around from the start, but you haven't noticed it.

I'm pushed to think that the "media" didn't report on it too much because the problems were economic. But as an average media company, that story doesn't sell, it doesn't interest the average reader, so they don't report it that much. Then the sexual harrasment scandal surfaced and _that_ is when the media jumped on board, because everybody loves getting political and hearing about scandals and feminism and all those kind of controversial topics.

If anything, the scandal damaged Uber's public image, but that is a superficial problem in proportion to their disasterous funding model and general financials.

What are the Best ethereum DApp ideas that haven't been launched yet?
Ethereum's decentralized and anonymous nature are great for some types of Dapps, such as prediction/betting and stablecoins. However, there are already many players on both these fields (e.g. Augur, Gnosis; Makercoin, Digix).

What do you guys see as great use cases for Ethereum DApps (i.e. an app that would be better on Ethereum that on a normal website) that have not been launched yet?
Zappa author here, thank you for your kind recommendation!

Lots more features in the pipeline, too!
They updated their ToS to reflect this.
I should have been more specific yes. I actually meant CPU-or-network-bound tasks with a predictable, sub-5min runtime.

Like I said we use it for game replay processing, so that's 5-15 second tasks that read and parse log files and hit a db and s3 with the results.

Other suitable tasks: image resizing, API chatter, bounded video transcoding, etc. Lambda is pretty good at distributed processing (as long as you can make the bill work in your favour, over hosting your own overprovisioned fleet).
Driverless cars and a lot of AI - to me these technologies are beginning, and Im expecting to see a lot of bad AI in the coming years before it settles down
For marketing-tech, sure it's a great model, but getting out an MVP as fast as possible doesn't always make sense. Sometimes it takes an order of magnitude more effort to get to "minimum" or "viable" depending on the product. On the contrary, a lot of developer's side projects just feel like things that any reasonably skilled developer could build given a few days.

The question of finding customers, is exactly the same as finding who is demanding software to solve business problems (i.e. not current software devs).
>Great source of reviews

This has not been the case for a long time, most Amazon products are filled to the brim with fake reviews and they do not appear to care at all.

They've also been having massive problems with fake chinese goods being sold as the real thing, which is compounded by said fake reviews on those products.

There is a reason Google, Intel and Apple are extremely paranoid about their internal data, and Walmart too. Its no coincidence this goes hand in hand with being very successful and leaders in their field.
Can you use fresh and saltwater in the same pipes? I feel like they would need to stay separate and having all the infrastructure duplicated and appliances able to switch between the two sounds expensive.
I use Lyft, which has always had tipping, and I don't find this to be an issue. Usually I am the one that starts the conversation. And I'm no fan of tipping in general, but there's a lot more to a ride besides conversation that someone might want to tip for.

That's not completely true, for AFL you have __AFL_INIT(), which defers the initialization of AFL until after an expensive initialization of the program to be fuzzed, which greatly improves performance.

Uber's valuation is still based on its growth. Therefore, it still needs to be a startup to justify this valuation and burn.

I'd argue that a "mature CEO" is not a fit for Uber which needs to keep growing or die.
Years ago I read The Wal-Mart Effect. Basically it was a whole slew of industries that Walmart had dramatically affected. Things like forcing vendors to manufacture in China and building a crazy infrastructure to get 'fresh' Salmon imported from Chile.

I got the impression they would turn the screws on industries to get cost savings via scale. This move seems odd.
> What was it like to quit your job and focus on your successful startup?

1. Time became my most valuable asset. Everything was filtered through the lens of "does this save me time?" and so I optimized everything: The gym (worked out at home), shopping (got delivered), dating (used fleshl...joking! :).

In the words of Joel Spolsky, "Every day that we spent not improving our products was a wasted day".

2. I worked harder than ever before. My job was tough but output ebbed and flowed with meetings, management, plus the usual office time wasters. The startup workday is more straightforward: wake up, coffee, write code, listen to users, coffee, learn how to add value to the market, coffee.

3. Every two months or so I look back and shake my head at how lame the product was, how little I knew, and how inefficient my workflow was. Which is to say, I continue to learn at an incredible clip yet realize I still don't know a thing. I expect this trend to continue - if it doesn't, I'm not growing.

So, yeah, overall it's been An Incredible Journey™. My only regret is that I didn't start sooner.

It's actually a gift how easy it is to go from idea to product to business. To paraphrase Murakami, 'If you're young and talented (or can code), it's like you have wings'.

Interview: Scott Forstall and Original iPhone Innovators
If Wal-Mart decrees this, put up or shut up. Welcome to business.

CEO Diktats about using not using competitor services for anything whatsoever, are as old as Microsoft. Wal-mart is not in the cloud business, so I can only wonder if, as others have commented, it is about data security in AWS domain, since Wal-Mart's main competitor is Amazon.

We know what Google and Facebook get up to with peoples data, why would Amazon not analyze or try similar to their customers? To have all that technical capability and not be curious about stuff would be a waste.

Finally, I think it would be great for everyone (except Amazon), if wal-mart got in to the cloud. Using their leverage to create cheaper cloud would benefit us all.

Think of the salary for an employee as the same as a retainer for a consultant. You are paid $x,xxx per month for your availability for xx hours per month. They can be all or none consumed. But more hours are not guaranteed (employees/consultants should be able to reject over time) and should be paid a different rate (higher).
Responding to Bogomipz:

> Can you walk me through the math. How does one arrive at 1K of Series A preferred from 9K of common stock? How is that being derived? I'm not following.

At time t=0 (probably at founding and when hiring its first few employees) Company X issued 9,000 shares of common stock. At time t=1 it decides to issue 1,000 shares in a series A offering (most likely to VCs and outside investors). They are separate events.

1000 shares x $1000/share = $1m raised for the company in the series A.

> Also what is meant by "post-money" valuation? I'm assuming there is a corresponding "pre-money"?

https://en.wikipedia.org/wiki/Pre-money_valuation

In this case, pre-money valuation of Company X = $10m - $1m = $9m

Using a more safer systems programming language like Modula-2 (1978), would prevent in regards to C:

- Out-of-bonds array and string access

- Implicit type conversions

- Accessing null pointers

- Using pointers for output parameters

- Casting integers to invalid enumeration values

- Incompatible casts between data types

- Allocating less memory than actually required

In Modula-2 anything that requires C like low level tricks requires the explicit use of the pseudo-module SYSTEM.

But I can go further to 1961 and ESPOOL and NEWP, Algol dialects for Burroughs B5500 systems programming, which already supported the use of then known as UNSAFE attributes for such low level coding outside Algol strong typing.

Although they would still allow for memory leaks or the error of freeing unallocated memory, but they would panic for the later, instead of the UB in C.

Skype was a started in Sweden, by a Swede and a Dane. They then however set up a dev office in Estonia where the initial client was developed and set up their headquarters in Luxembourg, I'm assuming for tax reasons. They have however always had offices in Stockholm. That being said Microsoft has announced that they're closing the Stockholm Skype office to consolidate the development to Estonia.
Actually, being put under probation after release means you are still considered a threat.

"Uber is profitable in certain cities, e.g. New York City [1]. They could turn cash-flow positive if they just gave up useless market share."

I would assume that would also depend on how much of their fixed costs they can shed in conjunction with that. Uber may not die quickly but it could still die slowly if they lose the ability to move forward because they had to cut too much of their R&D and sales infrastructure to get to that positive number.

Plus such a massive layoff would be a big red flag to customers too. By Uber's nature, a particular ride isn't a long-term commitment, but I think people would start looking for a stronger-looking horse even so. One of those differences between homo economus, who every time they need a ride rationally examines all their options regardless of the future and realizes that as long as Uber can complete this ride the internal state of Uber doesn't matter, and homo sapiens, who will take into account the fact that Uber doesn't seem to be doing well even if doesn't rationally matter at this particular point.

As a consumer, one of my fears with Amazon is that the price of Prime is going to skyrocket. Prime is $99USD/year which works out to $8.25/month for all of the bundled services. This included but is not limited to video streaming, music streaming, photo storage, and free 2 day shipping on all eligible items. No single service of any other comparable medium (Spotify, Netflix, Hulu, Play Music) offers the same service that prime offers at the same price.

Amazon tries to incentivize customers to use 5 day ground shipping by offering credit to Pantry to tries to push its credit card as a means of payment. Perhaps all their other services can continually subsidize Prime (as well as internal logistics management), but it feels like price hammer could fall at any time.
Thanks for the suggestion, but for a good reason, I couldn't be bothered to use some external service to do it, since it will be replaced with the actual product. Replacing that stupid mailto link is just another motivation to ship something :)
I have the overall feeling that most people don’t realize that parser combinators are nothing more that disguized recursive descent parsers. Personally I love both.

I wonder when we'll get directions on moon and mars
From a quick look at the doc (http://llvm.org/docs/LibFuzzer.html) this doesn't seem to be supported.

Aborting from an assert deep in the code has some challenges: unwinding the stack is ok, but how one would avoid memory leaks for heap data? It would require trapping all mallocs to track all allocated data and free it. Not impossible but it adds very significant complexity, and that doesn't seem the philosophy of libFuzzer. It seems to me that the goal of libFuzzer is to be very easy to use (just define one function for test harness, compile with CLANG and fuzzying flag, done) and efficient on an already reasonably well behaved library.

It makes sense to me: just start with AFL, which has no problems with crashes. When you reach AFL limits and need more efficiency, only then move to libFuzzer (both can shared state / test framework). Then the assumption that the app. is reasonably well behaved makes sense.

Caveat: I haven't used libFuzzer yet. For the reason above, I'm just using AFL for now. Maybe one day but I'm not there yet ;)

Thanks for sharing some real data. It's always interesting to see.

I too am surprised to see the conclusions come out as negative as this over such a large overall data set. Just from our own experience, even making quite modest changes to small web sites, it's not that unusual to see the kinds of change that came out with a negative mean in this report actually making a very noticeable positive difference.

I wonder whether this is partly a matter of interpretation and presentation. A lot of the treatments that had a slightly negative mean also had a lot of variance, which suggests that quite often those treatments do work but it's not reliable and requires experimentation to make sure you only keep the genuinely beneficial cases. It seems plausible that there were a few of the "75% improvement in our case study!" kinds of results lost in the long tails, but that what the data is telling us is that those really are outliers and don't happen nearly as often as we might wish.

You're right. However, the many other worse things Uber did than that sexual harassment case actualy do seem to be good for business - that's why for many years now I was hoping the governments will kill Uber. Unfortunately that did not happen, and it is this fact - not some narrative - that is dangerous, because there will be others willing to try out the "move fast and break laws" business model.

"So a person who is psychologically capable of murdering has more control over me than one who isn't,"

More relevantly, a person who is both capable and willing to restrict your freedoms, potentially even unto death, has more control over you than a person who doesn't.

This isn't abstract theory. This is a description of "government". Would you pay any attention to the people claiming to be "the government" if they didn't have credible mechanisms for backing up their demands?

It is preferable that government not be solely founded on this power relation. It shouldn't be considered "sufficient" for good government. But it is certainly "necessary".
What's there to predict? ARM has always had a stronger low-power presence than x86. Instead of hedging all bets on Atom, they should have kept XScale on hand as a second option. They still have a license to make ARM chips, but the capability that XScale presented never should have been sold.

I landed a contract to develop a saas system before I really knew how to program for the web, I had some prior systems programming experience but had not coded for about 5 years. I quit my job to develop it and delivered but was never able to land another customer.

I still have the original client 3 years later and the company grosses about $3,500 per month and I net $1,250. It pretty much runs itself, requires maybe 2 hours of work every 2 - 3 months. I spent a little over a year trying to grow it from the initial customer with no luck.

Landed a job as a full stack engineer afterwards and I really like it. I am actively looking to start a new project but I will keep my main job while doing it. I had the benefit of a wife who makes a good salary to support me during that prior adventure (Still do :) )
