Given eggs and sperm, and the means to preserve them for centuries, could an artificially intelligent machine possibly produce its own "children", so to speak?

Your question appears to be “given the ability to do X, can an intelligent agent do X?” I’d say the answer is, “Yes.” As you say, it has “everything it needs.”
There's really at least two layers to this. The first layer is the physical/biological side. Can an AI, without a female H. sapiens womb, produce viable H. sapiens individuals. The answer appears to be increasingly yes. For many years now, we have been able to artificially inseminate eggs. We're so good at it now that ...

Yes, the AI definitely would be able to do that. Assuming it gets a reason to do so (to avoid the entire point Tim tries to make) the AI would be able to build up and create a fullscale biological ecosystem.

Yes indeed that would be down to the stack space for the recursive calls.
O(log n) is nothing - just pointers requires such amount of memory.

It can be considered due to stack space ,also in every recursion you are dividing your array into two parts which for the whole process takes log N time which is quite unavoidable....

A friend has about 10K numbers in a an excel sheet. He wanted to encrypt these numbers in order to share the file with a 3rd party that will help him reorganize the tables.

In addition to what Richie has noted, here are some problems with the encryption method that you normally don't like to see in encryption. It preserves order (if a > b, then E(a) > E(b)). So, say the cells encode salary information. Even if it doesn't reveal the salary, it still reveals a lot of information. It is no...
From the information we can describe the encryption algorithm as follows. Given a floating point number (m) and there is some number (nx) where m \* nx = kx. kx is the encrypted number where x is some position in the list of 10,000 numbers. So know that nx is going to be some realistic data. In this case you pointed ...

Same problem here with my Tecra R840 with Alps touchpad. It's definitely a regression in 12.04. It can slightly be diminished by changing the values of HorizHysteresis and VertHysteresis via synclient (see synaptics manpage). But the problem still exists. And yes, it really is very annoying and the reason why I don't ...
You may want to try entering "synclient" in the terminal to see what your FingerHigh & FingerLow values are. In my case, the movement was occurring with taps being recognized as released too early.

I'm implementing a GUI system to look around a 2D tile-based world. At the moment, I'm updating it every time the mouse moves (which happens to be per frame, since that's when it polls for events).

What's the context? For UI, it's very sensible to poll per-frame, especially for cases where the UI and the game simulation have no good reason to be tied together, e.g. highlights when you mouse over a selectable object. For control of a character or the like inside the game simulation, this advice can be flipped. C...
It depends on what you want to do, whether it's GUI-like or game-like. Most game situations only care about **where the mouse is right now**, so you go through all the mouse move events and simply act on the last one. This would be **per-frame**. One example is using the mouse to look. However, there are some GUI-lik...

If your environment's noise level allows it, you can use a quiet no-brainer solution.

A good advice would be to load the sound file into Audacity, and look at the spectrogram (FFT) representation in there. Impact (impulse) sounds are easily spotted visually in the spectrogram, as they're sharp vertical lines. Echo's may trail, so the right side is usually a bit fuzzy. That also gives you the simple alg...

Can a human eye perceive a difference between an image that takes 150ms to load and another image that takes 160ms to download? If a page has 30-40 images, then does this 10ms difference start making a difference?

10 ms might be just barely noticeable. On a typical laptop with a refresh rate of 60 Hz, each frame is on the screen for about 16-17 ms, so (all else being equal) a 10 ms delay means a roughly 66% chance of making the image show up one frame later. However, a 1-frame delay (which is the maximum delay possible as a res...
If the page takes 150 ms to load and the image takes 160ms that's 310 ms total. The human eye can read 10-12 images per a second, or about 1 every 100 ms's. So yes they would notice the loading if they looked hard enough.

You should try out a standard text editor like Sublime Text or Atom. Do your code editing there and open your page in the browser. Refresh to see changes as you make them.
I like Notepad++. The problem with programs like DreamWeaver is that they can instill some pretty bad habits in novices. You are absolutely right in wanting to learn without it first. The reason I like Notepad++ is that it has great code highlighting, one of the things I think draws people in to DW, too.

I figured out the problem. It's still a bug, and wireframe still gets stuck on, but all I need to do to fix it is go to a different frame in the timeline. Then, the stuck wireframe goes away. Just scrub the timeline to fix.
One more issue: Sometimes the wireframe overlay would get stuck on, but it would only be on certain objects and not others. Scrubbing timeline didn't fix it for me. All you need to do is go in and out of edit mode on the effected objects and the stuck overlay goes away.

Use a scheduler like [Quartz](http://www.quartz-scheduler.org/) or [cron4j](http://www.sauronsoftware.it/projects/cron4j/) (pretty decent library and more lightweight than Quartz).
The [Hudson](http://hudson-ci.org/) integration server does exactly the same (in Java). It even implements the cron syntax allowing complex schedules. And it's [open source](http://wiki.hudson-ci.org/display/HUDSON/Source+code).

I'm designing a FET gate driver that allows 1.8V MCUs to control FETs up to 100kHz. FETs to be used will vary a lot so I'd like to have as much current drive as I can.

I think without resistor (and zener) values and specific BJTs there's not much that can be said other than "looks ok", except you'll mostly likely want a decoupling cap in parallel with your push-pull stage.

Using ad spend (or any marketing instrument) in a model predicting unit sales is pretty standard. To your very good point, it is almost always endogenous, e.g., ad spend is frequently a percentage of sales revenue as in the A/S ratio. The statistical solutions are to create and model HAC residuals for the DV and then r...
If you are saying that the spending falls into different groups or categories (e.g. different seasons) then lumping them all together breaks the assumption of independence of observations. E.g. if the observations for spring constitute one group of observations, and the observations for Christmas constitute a different...

It is hard to say what can go wrong without seeing your JMeter configuration, full server response, JMeter and application under test logs and network dump for browser and JMeter. The whole idea of performance testing is mimicking real user as close as possible, so you need at least 1. Add [HTTP Request Defaults](ht...
beside, what Dmitri described above, I would also check the actual throughput the server returns in either cases. Throughput depends a lot on the timers you configured in Jmeter to simulate think time. Jmeter has no rendering and no javascript engine, so each thread is much much faster than a real browser.

Just for future readers, I ended up bringing in structural engineers who found my basement wall was **bowing** from the stress of the soil outside the house (becomming water-logged, freezing, expanding, etc.). This was also the cause of the vertical crack/fissure that opened up, which was my chief complaint in the orig...
It depends a bit on what the actual problem is. A mason won't likely have the answers you need, which are related to water management. If it's a surface drainage issue, call a landscaper to raise grade and create slope, and/or a rain gutter specialist. If it's a water table problem, call an excavator to install ext...

Suppose you are being interviewed for a job, and while you're making a presentation, you find yourself (in a fit) excessively hand gesturing to the obvious inconvenience of the interviewer. Now you would like to apologize for that: > > I'm sorry for making too much gestures. > > > I'm sorry for being excessive with...

A way you could express your apology is to say "sorry for waving my hands so much"

I started learning a PCB designing software and successfully made a working PCB prototype containing two Arduinos, RTC, external EEPROM, RF module and some other components on a single board all within two weeks. This is how I did it: Selection of PCB designing software - I chose Eagle because: * It's free but with ...
If you use Eagle you can load the Arduino files into it and create your own template - the boards were designed using Eagle. I use Pulsonix PCB software, and imported the files to create a template for that program. You can then create your own shields.

There is very little to gain from reusing the Arduino files, as the basic construction is so simple, so don't put too much value in that, it's much more important that you understand what's going on and you get a good EDA package that you can use.

Usually, when you encounter EAGLE for the first time, your biggest challenge will be to find foot prints for the most commonly used parts such as - Resistors, Capacitors, Voltage regulators, etc. I have compiled a small list of most commonly used component libraries in Eagle, it will help you to get started with PCB ...

Whatever CAD package you use (I use Eagle and the "limitations" have never caused me any grief so far), what you're going to need is gerber files. In Eagle you generate these using what's called a CAM job (I use the [one from Sparkfun](http://www.sparkfun.com/tutorial/Eagle-DFM/sfe-gerb274x.cam)). Incidentally, the [Sp...

I think is is a problem with BlueZ and Bluetooth 4.0 low power devices. This past week I tried the Microsoft Arc Touch mouse which is Bluetooth 4.0 and although it would pair its type showed up as Unknown and obviously was not useable as a mouse. I then bought & tried the Lenovo N700 which again is Bluetooth 4.0 and ...
First try to find your bluetooth in additional drives, if it won't help you have to find your bluetooth driver and install it from oem's site. If you don't know the id of your bluetoot (most probably it's together with your wireless card) by entering`sudo lshw`
