IPhone Application Development- App Store Problem-Financial 
Those who deal with Apple app store may have encounter this problem any time and may wonder why this is so. I have given some clue.
It did not use Visual Basic for Applications (VBA), but it did use Access Basic. Which was a dialect of Visual Basic.

Access 95 had the ability to upgrade from Access 2, and that included the ability to migrate from Access Basic to VBA. The tool was not flawless (very little from Microsoft is), but mostly worked pretty well.

Word of caution. If one person is still employed, but the other is not, it makes for a very difficult partnership. There's just a lot of risk that the work distribution will eventually become too imbalanced; either your partner will burn out way faster than you'd expect, or you'll be too annoyed with the lack of effort that your partner puts in.

Not saying this will happen to you guys. Just saying there's a risk. Speaking from personal experience.

> Stop being so paranoid about what you think you can't hear, and enjoy the damn music.

Yes. Do a couple of blind tests with your acoustic system first.

> It's true enough that a properly encoded Ogg file (or MP3, or AAC file) will be indistinguishable from the original at a moderate bitrate.

Disagree. This claim seems to be ungrounded compared with others.

I can believe limitations with bit depth and sampling rate (although I'll take a chance to test myself if I get near good enough acoustic system). However, I definitely could discern in a blind test whether music I listened to was stored using lossy format with reasonable bitrate. It's usually quite audible with rock music that involves cymbals.
Yeah, it looks like I got that part wrong. (I intentionally skimmed over the transactor, because I was avoiding "how" issues and because my understanding of it wasn't that clear.)

The transactor is involved in just writes, not reads. (So that helps.) It's not distributed and cannot be distributed, in this system, because it ensures consistency, so yes, it is potentially a bottleneck. In blog comments by Rich Hickey[1], he states:

"Writes can’t be distributed, and that is one of the many tradeoffs that preclude the possibility of any universal data solution. The idea is that, by stripping out all the other work normally done by the server (queries, reads, locking, disk sync), many workloads will be supported by this configuration. We don’t target the highest write volumes, as those workloads require different tradeoffs."

Presumably, 1) the creators of Datomic think that performance can be good enough to be useful, 2) this is a new model that probably requires testing to prove is practical.

It's not always that simple. What if that person quit their last job to come work here? Quit and moved across the country? Gave up other promising opportunities?

I'm not saying you can't fire people, but unless a trial period is explicitly agreed upon beforehand, there's an expectation that a job will last more than a couple of months if the new employee is putting in real effort. I don't know where to draw the line, but even an employee who isn't a dick might sue if they rearranged their life only to be let go two months later; I'd argue that they also deserve to win.

I've mentioned this before on HN, I've been given 'homework' after the whiteboard-interview. If they aren't following this:

, then run run away. I ended up doing my not-so-little assignment but I realized he just wanted the unit of work, not an actual employee.

If anyone is in a similar situation and you have the time to do the work, you could do it. Then come in with your laptop with your code and show it to them in the next interview. Don't let someone take advantage of you.
The warning is appearing for me (FF 10.0 on Ubuntu 11.10). It might have just taken time to propogate.
I don't think there were price decreases of the hourly prices for EC2 instances - previous decreases were for traffic, or introducing reserved instances where you get lower price in exchange for commitment.

I think trying to factor in future price decreases in an ec2 cost model doesn't make sense - it is too little and unpredictable to worry about. Don't forget that if you reserve an instance for 3 years and Amazon drops prices, you'd get only partial savings on the hourly fraction of the cost. Even as I use Amazon for hosting (instances running full time) I stay away from the 3 yrs reserved instances because I want to be able to reevaluate my options more frequently.
> Modern (i.e. anything from 1995 onwards) DACs do not suffer from aliasing problems.

True, but they do so using (long, high-quality) high-cut filters. And these filters are pretty sharp, as they have to close within, say, 18-22.1 kHz. You can design them as linear-phase FIR filters with oversampling and all the good stuff, but physics dictates that sharp filters introduce distortion. A sharp filter like that is audible.
In case anyone believes this comment (that "until recently" there have even no price drops), I will throw in an alternative anecdote (as I'm at a restaurant and am not interested anyway in digging up alternative evidence: readers can do that themselves), Amazon has decreased their prices for all kinds of things many times; bandwidth quite often, servers a few times... I actually find myself misquoting Amazon's prices in conversations often due to having lost track of random price drops.

The one thing that hasn't dropped is where 99% of my costs are: the price of a PUT to S3.
Well, I didn't see/hear anything about what they were firing, so I assumed they were dumb bombs or shells.

Chakra Balancing is very important for religious advancement
Chakra balancing deals with both the body and spirit. The chakras cure the physical body releasing piled up chunks build up through a lifetime of traumas and negative practices. There are hundreds of chakras spinning ideally in a clockwise direction, attracting healthy energy for us to absorb, while at the same time, throwing off negative energy we no longer need. The healthier the chakra, the more energy we attract.

Their "efficiency" is light output vs electrical input. The result is actually that it starts converting heat as well as electricity into light. So you get more energy in light out than you put electricity in. You just put more energy in than electricity.

48kHz already has enough 'wiggle room'. How many people do you personally know that can hear a 24kHz sine tone?

> more granular timing for the start and stop of transients.
... it's something I don't see mentioned often.

Probably because it doesn't make sense. Human ears cannot hear frequencies about 24kHz and Nyquist tells us that 48kHz is enough to completely capture all the detail of a signal at that frequency and below.
This is often times the case. However, you loose several weeks doing the audition and you loose a few good candidates who took the offers that did not require the audition.

But then for every 10 people like you there is 1 person who is willing to pay 20x as much so they can get a "higher fidelity" product.

For a producer and manufacturer the rational approach would be to cater to that craziness and extract as much money from it as possible. In other words if you are selling HDMI cables, spend $2/cable to make it, then sell most for $5 and then re-brand some and sell for $500. If only takes 1 out of 100 people to buying that to make the same profit. You know these people are obsessed and irrational so you cater to that. And that's basically how we end up with ridiculously overpriced Monster cables and recordings distributed to customers @ 192kHz.

We're talking about two different things -- price drops vs. discounts.

They drop prices across the board all the time. They don't do individual negotiated prices at time T which are different for one customer vs. another customer. (they just started doing this a few months ago, in the form of offering special services to some customers but not others, and now in terms of volume pricing discounts).

All hosting providers drop prices over time (mainly by increasing the amount of RAM per server at the same price, vs. dropping the pricing of packages) for some things (and tend to raise for power, cooling, and physical space). But everyone except Amazon usually also does individual negotiation of prices.

I have all the sysadmin skills needed to run dedicated servers and in fact I was running and configuring most of our development and production systems for years. We did switch to Heroku for most of development and production projects lately and the difference in "time spent doing stupid IT" was enormous. literally tens of hours per month that I'm not spending now on starting, stopping, configuring, figuring out why the puppet install script fails thought it was working perfectly the last time, monitoring, etc, etc, etc. HUGE gains in productivity and totally worth the extra cost.

It all depends on how much you value your time. We are a consulting web dev house, so figuring out the price per hours is easy - its just what we bill our clients; but even for a regular startup it should be fairly straight forward. And this doesn't even take into account the opportunity cost. The cost of not doing something directly relevant for your startup outcome while you are fiddling with the servers.

>Well, if you end up firing a lot of people, give recruiting to someone who's a better judge of character.

It's not just about judging character. It's about the amount of effort an employer puts into the interviewing and hiring process. Interviewing people well takes effort. But if you're willing to fire someone easily, well, why put in the effort?

In my experience, this feeds back on itself. The more comfortable the employer gets with firing, the sloppier the hiring process gets. Soon good people start avoiding the company, which means mediocre people get interviewed. So the interview standards need to drop further, otherwise no one would get hired at all (and besides, you can just fire them if it doesn't work out, so what's the harm?). Pretty soon you're one of those companies with constant churn, where no one seems to last longer than a year.

>Firing when things do not work out is an honest act. What does it have to do with disposability?

It's not about honesty, it's about empathy. A good employer empathizes enough with the employee enough so that they find firing to be painful, even if the firing is justified. But an employer who cannot, or will not, empathize with their employee basically treats their employee as a thing. And if they treat employees as things when it comes to firing, they'll treat them as things all the time. Which is an excellent way to create a terrible work environment.
They turned heat into light using electricity. That may not be what people were thinking when reading the title/article, but I find this very cool, and I did not previously know it was possible.
I'm not sure if this would work the same way, but I know that some high voltage LEDs are actually just strings of multiple LEDs in series [1]. Though it clearly wouldn't reach the inflated efficiency in this article, this could lead to a chip with a large number of very very small LEDs reaching a higher efficiency than a standard LED. It obviously depends on the manufacturing process though.

[1] http://www.cree.com/products/pdf/led%20arrays.pdf
Most cooling systems are seem pretty complex/bulky/energy-inefficient to an ignorant sob like me, but if they can make it simple enough to fit into an LED, and the fact that this cooling system relies only on optical output and electricity, it could have a lot of cool applications we haven't thought of.
Or perhaps it should be renamed, "Why the cloud IS for your startup."

This explains how it's cheaper to deploy on metal for high traffic sites, as if $1000/month in server costs in the event that my site gets massive traffic matters.

With Heroku, I can have a site up and running in minutes with zero sysadmin work and almost no monthly cost. Should my site get hammered, I'm happy to pay $1000, heck $3000 per month, for a few months should it be necessary to handle traffic until I get my act together to reduce costs on dedicated servers. At that price, you can be damn sure you get good support from Heroku.

Compare that to spending a large portion, or even a small portion, of energy and time that could be dedicated to building your product before you even know if you'll get traction - I'll take the cloud any day.

If sysadmin work is so easy to learn, or to farm out with money, it can wait until I need it.
Have to show some support for this post.

Engineering is a combination of technology and art. Therefore, it is impossible to have a simple process for interviewing engineers that magically works. Otherwise, such posts would not have been brought up so many times in HN.

Also, some people are good at people evaluation, some are not. An excellent engineer could be a lousy interviewer. On the other hand, a mediocre engineer is lack of the ability to evaluate a top engineer within an hour. Therefore, the employer must first know who are his/her best interviewers. If s/he can't identify her/his own people, I highly doubt s/he is able to identify good candidates.

The hiring signals I pay attention to are one's curiosity and one's depth in understanding in at least one programming language or one computer science topic, no matter if that topic or programming language has any relevance to the position to be filled. Here is the rationale. To be a very good engineer, one needs both internal motivation and intelligence. Both of the two signals speak for internal motivation. A deep understanding on any topic shows the candidate is sufficiently intelligent. Such a candidate, even if s/he knows little about the languages and/or the frameworks the position requires, s/he would learn it very fast and would be very good at it. To be realistic, it is really not hard to learn a programming language and a framework.
Oh goodie, yet another checklist for people who don't know how to hire. Not that I claim to be awesome at it, but hiring and interviewing people is a skill, just like programming. It's not something you can get right by just having a checklist.

Despite all the cute anecdotes we like to tell about clueless HR people, it is actually a real profession, one we could learn a lot from if we weren't so busy circlejerking about coding tests and whatnot.
Although the OP talks about update_attributes, the problem is not limited to that method. The problem is with "mass assignment". So, if you are passing a hash of attributes and values to the new or create method of a model, then you are doing mass assignment, and you are exposed to this issue.

For example, if you are doing this in your controller:

@user = User.new(params[:user])

then you are doing mass assignment.
