At first, I thought you were preaching to the converted, here. Whether or not everyone here uses dedicated testers, they probably all appreciate the value of a well tested system. In theory, that is in fact the case, but reflecting on my experience this is not usually the case in practice. Testing is dropped by the wayside when the rubber meets the road - particularly in any early to mid stage ventures.

IMHO there is a strong cultural component at play. Testers are, quite frankly, second class citizens in the land of software. This is due in part to the ambiguity of the term itself, as it can mean everything from a button-clicker to an engineer (with perception often defaulting to the former).

As a result, testing becomes unsexy. Few developers with options choose to do it full time, and it becomes an afterthought. Even dev-centric approaches like TDD get brushed off as "crutches" for "junior" engineers. This all helps propagate a fairly downward-tending cycle of testers and testing lacking voice and status within the organization.
There needs to be a name for the fallacy where people discuss trades as if prices could only move in one direction. That, obviously, is the only way you can frame a discussion of trading in terms of "discounts". In reality, an entity that takes a position in an instrument also bears the downside risk for that instrument. Averaged out, it is exactly as likely that an HFT shields an unwitting potential buyer from a loss as it is that they snipe away the profits from that sale.

The value provided by "middle men", be they robots or crooked traders in pits, is liquidity and price discovery. Trading allows people holding an instrument to unload it more quickly rather than waiting to convince themselves to take a bigger leap on pricing; it's what, in a simplifier Bohr-model kind of way of looking at stock trading, allows you to buy shares in a stock at a market price you can look up online as opposed to waiting for the stars to align. The faster the trading, the lower the spread, the smaller the leap sellers and buyers have to take.

It's worth noting again as always that before automated and program trading, spreads were higher, and the space in the spread between the bid and the ask was basically a license to steal.

Here's a good comment from awhile ago, including a cite to an accessible paper:

Ah yes, under that interpretation I would agree wholeheartedly.

I picked up "silence on the wire" which felt like a good introduction to tcp level penetration.
The value to my clients comes in two forms: (1) amount of tax saved and (2) stress and fear eliminated.

The first is easy to quantify. It also means there is an upper cap on your income. The upper cap is the amount of tax saved. As your price approaches that number, the likelihood of a "yes" decreases.

Do not set your pricing based on easily quantifiable criteria, unless you're working on huge deals where you can take a small fraction of the value as compensation. (By small I mean low single digit percentages).

The second is where the true value sits. People are willing to exchange money for a peaceful brain. People are willing to exchange money in exchange for more time in their lives. It is here that personal value choice discontinuities work in your favor. Set your pricing based on intangibles.

A business owner is willing to throw money at a problem to not have to think about the problem at all. This frees up the owner's brain to think about stuff that really matters and will make money.

An hour spent by a CEO looking at tax returns could be an hour taken away from making a deal that brings in $1 million for the company. It's worth spending $1,000 to make the problem go away. You are happy to take the $1,000 because it takes you $125 of time input to solve that problem.

I have seen this with very large companies. There is a reason why their compensation packages include "your employer will pay for a lawyer, accountant, and personal financial planner." You don't want an executive with 10,000 employees under him/her to be sweating credit card payments, or "Is my will up to date?" or any trivia like that.

Moreso, however, I see this with entrepreneur-driven companies. The owner is the manager and this person's time is incredibly valuable and should not be spent on trivia, especially emotion-laden trivia.

The author structured his article as a rant and it shows, so I won't respond to every point. The central premise of his post is that B&N is in an innovators dilemma situation and will find it impossible to build ereaders. Then the author suggests it should build a reading app instead and just plow all its resources into that. Except it would have no content network behind it. Ergo:

>>Or, if B&N can talk publishers off the DRM ledge and onto the watermarking perch, they could just switch to using iBooks when on iOS and have a book delivery app that doesn’t do anything but notify people when new books are ready to be copied into iBooks.

Wow, why isn't this guy CEO? So in other words Amazon and B&N should get rid of their delivery networks and build a better reading application that will compete against apple which has:

1) a device 2) a content delivery network 3) a proprietary delivery format that they can add new features to 4) a builtin application

And the value proposition is the reader app is better? Well, it if its you don't need to do anything the author suggests. You just need to improve your e-reading application.

The author confuses needing to understand where the market is going with making up a fantasy world where nothing you have done to support your existing business should be accepted.

Really, the author is not stretching the meaning of the word deviant. It has always meant deviating from an accepted norm, and it means the same in this context. The social norm was to feed your kid rice 2x per day- the social deviants were the ones feeding their kids more often and animal proteins/greens. They were abnormal. The difference is we are used to hearing negative examples of deviance (crime, etc) when there are plenty of positive ones.

Deviance (a relative concept) is not the same as perversion (a moral concept).

Yep. As a web development shop, finding a client that understands or can be convinced of the value of any testing is rare.

Physical access is god access. Admin/root is god access.

Guard them both with your life.

I fail to see how handing over control of your boot to some 3rd party who clearly doesn't have the same interests that you do is anything but a horrible idea.

Just physically secure your boxes(or VDI them) and use permissions and ACLs to do what they were designed to do[control and delegate authority].

A good first step for Microsoft, if it cares so much about security, is to stop making its users automagically admin for fogging a mirror, during new PC setup.

Project Update #19: Ouya is Coming
No, my math is right. It takes a lot more effort and money to move a large mass.

> Kindly explain how some foreign countries with highly regulated or state-operated telecommunications companies already have faster internet connections than major American cities.

Because their infrastructure decisions come after our infrastructure decisions.

It takes N years to "wire" a large city like Los Angeles. After that you have to get your money back. Yes, that is not a criminal act. Meanwhile country "X", many years later, looks at what was done in Los Angeles, checks out the more current technological offerings and installs a system that yes, probably leapfrogs what the average customer in Los Angeles has.

The true test would be the next evolutionary step. When a city like Los Angeles is ready to make the next big shift in connectivity it will be really neat. Country "X" will then fall behind and it will probably be very, very difficult for them to make the next leap 'cause, well, they have to pay for the investment just as well.

The technology that is going to make a huge difference is fiber to the home. We already have it in certain places in Los Angeles. I happen to know that there's fiber in the telco box right outside my house. Why? I saw it being installed fifteen years ago. Not lit yet. It will be, eventually. Fiber is great in that you can greatly enhance transmission rates by driving it differently. There's probably a few more evolutionary steps ahead of us before fiber bandwidth is tapped out.

There's another issue a lot of people might not consider when thinking about upgrading the infrastructure of a country like the US. If tomorrow we all had 1Gb/s service at home and at work it would probably crash the Internet. The infrastructure required in order to support something like that at our scale is massive and cost a ton of money. I don't know if costs are geometric or exponential. They are huge. A small country has advantages here as well.

No, government and regulation is not the solution. It never is.

Thanks for this, I forgot to mention about Numenta. Your comment prompted me to search my old archives for the setup file to "Vitamin D Video", a motion and object detection program that was a very early example of Numenta technology being successfully implemented.

Even the really early versions of Vitamin D were impressive. Anybody use it for anything interesting now?

Jupiter is too large for anyone to get their head around. It's too far away and just too alien for an impact to have any effect on the population.

On the other hand, Mars has been the subject of countless fantasies and observations, we have the surface well mapped and if we get a good look at the impact crater (or the impact itself) it will be a matter of hours before someone overlays a map of NYC or London on the imagery.

Mars being smaller than Earth also adds a lot of weight to the discussion. Something hitting Jupiter is just not unexpected, but if our smaller sibling gets struck then there is something to talk about.

Charging for value is a nice idea. How practical it is depends on a lot of things including how predictable the outcomes are and what the standard practice is. And, as your parable suggests, if you do bill by the hour/day, your rates are going to have to reflect (assuming you want to make a decent living and stay in the business) what percentage of your time can realistically be billable.

When I was doing IT advisory work for vendors, a fairly small percentage of my time was spent doing direct billable work for clients over and above annual subscriptions many of them paid us. The rest of the time was spent researching, being briefed by companies, talking to journalists, writing, etc. When we did do a specific project (for which we generally charged for a deliverable--although that deliverable could be a day of advisory work), we charged what would seem to most people a really high hourly rate because we had to capture all the non-billabel time (and, of course, because our rates were in line with industry norms for this type of work and companies apparently felt we delivered sufficient value to capture those rates).

By contrast, I did some legal work as well and for that was paid on an hourly basis at a much lower rate. But, because it was a big block of work and I could charge for any time related to the project--including travel, background reading, etc.--it was pretty good work.
I've created dozens of sites and never really noticed any CSS performance issues.

I have got orders of magnitude faster sites by combining CSS or js files, gzipping content, adding cache control headers, serving via a cdn and not serving code that's not used.

I've also really benefitted from using logical markup and CSS selectors, not those designed for "efficiency" of the computer rendering them.
"Now millions of people share in the fun."

But is it profitable? I have built a fun, big site in the past, but I couldn't keep paying for the servers. Now I know it's not as easy as "build something cool, users will come, and money will follow"
Yes, it's possible with certain kinds of algorithms. A while back IBM found a way to do general computation on data without decrypting it, like adding encrypted dollar amounts together etc. But it's about a million times slower than normal data processing.
A heuristic is a bit more complex than an indexOf. I just tried it myself: An email just containing the phrase "barely legal teens" is attributed by Apples iCloud IMAP servers in the header a "spamscore" of 3 and is delivered, but marked as likely spam:

> X-Proofpoint-Spam-Details: rule=notspam policy=default score=3 spamscore=3 ipscore=0 suspectscore=2 phishscore=0 bulkscore=1 adultscore=73 classifier=spam adjust=0 reason=mlx scancount=1 engine=6.0.2-1212290000 definitions=main-1302280125

I would argue that this kind of filtering is fine. Maybe it was a glitch in the server, maybe other metrics of the mail pushed the spamscore up. If iClouds Mail servers should silently decline mails for delivery is a whole different argument.

A macbook air running on ARM with a cellular moden is inevitable or at least I hope Apple is thinking the same way I'm thinking :).

I'd be really excited to see an iOS device that integrates in the way that you'e described. Rather than changing the form factor of an iPad, which in my opinion is near-perfect, having it launch OSX or some similar windowed system after recognizing a bluetooth keyboard/mouse, and a monitor connected via the dock connector would be incredible. I would then have a great portable consumption device that I can actually get work done with when I'm in the proper environment.

I just hope Apple doesn't forget about the Unix underneath which is just so helpful to me as a developer.

Problems exist to be solved, fracking's problems are no exception and the reward is progress.

Yes, we just need to get the drilling industry to recognize there is a problem. Necessity is the mother of invention, and regulation is good way to create necessity. Auto manufacturers fought clean air restrictions and fuel efficiency requirements, but those regulations spurred them to innovate. I'm sure the drillers would as well.

> That is one of the most fundamentally Moral statements I have ever seen. Try replacing "development" with education. Or even better replace "development" with "raising your children".

The essence of the positive deviance idea is to let the children raise themselves by abandoning the methods of their parents (of tradition) and instead monitoring the best practices of their peers, but I suspect parents would (with some justice) object to this interpretation.

I also usually insert a "Paused" between TODO and Doing in case a "Doing" task stalls out. Rather than putting it back into TODO, I use Paused to indicate that once the issue that's causing it to stall is remedied, it's at the absolute top of the priority queue to get worked on.
I would. If this was available here in NJ, I'd be on it in a heartbeat. TJs and WF are two of my favorite stores and they're both relatively far from me, about 25 minutes away. Add the time spent finding items on shelves and I would be looking at a serious time saver.

Make no mistake, I'm not against real innovations. For example, I've been using git and advocating for it, while many of my peers are still with older CVS systems.

The point is if you masquerade a solution to a non-problem with pretty things, it just wastes everyone's time and energy.

Like I said, it would be interesting if there is a study to find out if any of these pretty task management tools actually increases productivity.
