If you want to succeed in anything, forget practicing and start networking.

That sounds like a pretty caustic view of the world. Firstly, the title says to be an expert, not about "succeeding" in anything. And secondly -- as I read it -- you're equating success with earning money in business.

My biggest successes don't have anything whatsoever to do with the success as you describe it:
- I've grown to be a software craftsman
- I have become a gentle and present dad
- I've learned to handle money well
- I can have a nice relationship with a pretty woman
- I've conquered a depression

But please go on, and start "networking" to gain some of that empty success.

Resting and waking heart rate are often confused

It would have been helpful if you explained the difference. Google is not very helpful for "waking heart rate", but "resting heart rate" seems to be the one that you have when you wake up in the morning.

It seems that I don't have a clue what you're trying to say. In lactose-tolerant people, lactose is broken down by enzymes produced by the human body, and the reaction product is absorbed. Lactose-intolerant people don't produce that enzyme. What specifically mutated bacteria that take care of the lactose in a benign or less pleasant way are you referring to? And what statement exactly do you wish to have a reference for?

What I was trying to say: if the intestine does not absorb nearly all the carbohydrates that are in the food, you will get sick. Since people don't get sick (bloating, flatulence, etc.) all the time from their normal diet, it must mean that the intestine absorbs nearly everything in their diet.

Comment Keeping it cheap and low-energy (Score 1) 287

I was using an old netbook (Atom N270) as a home media server, keeping it running Ubuntu Desktop 9.something. But it was too much of a pain to maintain: keeping it on mains power for a year seems to break the battery-charge-level monitoring, which makes the internal battery useless as a UPS. Too many processes insisted on writing to files every 5 minutes, which was spinning up the hard disk all the time. Also, it got uncomfortably hot with the lid closed all the time.

So I got a second-hand thin client (Via 1 GHz CPU, 1 GB internal flash drive, 1 GB RAM, gigabit ethernet) for 75 euros, installed Ubuntu Server 12.04 and a USB hard disk that has a auto spin-down feature. The 1 GiB "SSD" turned out to be too small for OS and log files, so I augmented it with a 4 GB USB thumb drive, while cursing that it is very hard to find one that performs well on lots of small writes (With 4 kB random block write tests, the throughput of most sticks is less than 0.01 MB/s). This thing takes about 13 W of power while idle (26 euros/year at our rates) and last time I looked, there are no alternatives on the market that have comparable horsepower for much less watts. The server hosts media files (MiniDLNA) and backups (snapshots) of the various computers/tablets/phones. Once or twice a year, I sync the disk with an external USB drive. If my house goes up in flames, all will be gone.

Since my media storage is mostly audio, a 1 TB drive is plenty. When I read here from people that have 40 TB of storage in NAS arrays, I wonder what they are hoarding. At 5 GB per hour of video, that's 8000 hours!

Ubuntu 12.04 server sucks for a headless server. I think it was waiting for a keypress after an unclean boot. (There was a comment on a forum of a guy who had to drive 100 miles to a datacenter to attach a keyboard and press Enter). That one was solved, but now it just hangs during filesystem checking at boot time - some bad boot-order dependency.

Network: ethernet in living room (A/V center) and work room (desktop/printer); wifi elsewhere. Visitors get the wifi password. Non-media file transfers and backups are always over ssh. (It t1urns out that the gigabit ethernet was overkill; the VIA CPU can barely saturate a 100 Mbps ethernet line, with the faster SSH cipher (arcfour).

"your body isn't absorbing every calorie you put into it. Your body absorbs until it has what it needs"

Consider what happens if a lactose-intolerant person drinks a glass or two of milk: about 25 g of carbohydrates that their body can't absorb. It will lead to flatulence and diarrhea as a result of gut bacteria feasting on those unused calories and the inability of the body to extract water effectively from a sugar solution.

The fact that this is an abnormal response shows that the normal thing is to absorb every calorie.

"I don't know if the plant really needs the caffeine for something else"

I've been told that it's basically an insecticide. Arabica plants contain less caffeine than robusta plants, and are therefore more sensitive to pests. Naturally caffeine-free plants would be a pain to cultivate.

" I always just use split horizon DNS, and put everything under the corporate domain name, thus eliminating the problem."

I have something like that at home, a registered domain name example.com and a portion *.home.example.com that was only resolvable from my lan.

Then, a few months back, I upgraded to the new Linux Mint LTS, which did all queries simultaneously to my ISP (fallback DNS) and my LAN DNS, using the first response. Sometimes the ISP was faster, resulting in 'nonexistent host' errors.

It took me an hour to figure out what was wrong and how to repair it (networkmanager.conf, disable dnsmasq). Sigh. I wasn't the first to have this problem. The devs didn't really see the problem. https://bugs.launchpad.net/ubu...
