Walgreens To Build First Self-Powered Retail Store

TheStonepedo Re:Lighting Choices Are Not Extraordinary (186 comments)

As an MEP guy I find your ideas intriguing and would like to subscribe to your newsletter.
Will I see you at next year's ASHRAE or LightFair conference?

Walgreens To Build First Self-Powered Retail Store

TheStonepedo Re:Lighting Choices Are Not Extraordinary (186 comments)

I picked lighting because it was the most-obvious waste of words in the article for the sake of green spin.

The "geothermal" mentioned in TFS (who reads articles, really?) is likely a ground source heat pump rather than a subterranean heat source/sink.
I like the efficiency numbers of such heat pumps, but am concerned about diminishing returns over time in areas with unbalanced heating and cooling seasons.
Evanston, IL is close to Chicago - 6450 HDD65, 750 CDD65 .
Assuming the target temperature is 65F (although 70-75 is more realistic in the US) and ignoring heat generation within the space (minimized by using "green" electronics and lighting), the pump could be pulling heat from the ground about 8 times as often as it puts heat into the ground.
This would tend to cool that ground over time, barring external influences.
The well field in what should be a heat source will be warmer than the ambient air on cool days at first, then on cold days after a few cycles, then only on the coldest days.
Once that has happened, they may as well have chosen an air-source heat pump (current models meet their design heat output to around 4F without significant efficiency loss) and foregone the cost of wells.

"Ultra-high efficiency refrigeration" sounds pretty cool.
I was under the impression that regulation of refrigerants to minimize ozone depletion (while in turn increasing global warming potential, but that's a different conversation) led to refrigerant cocktails operating at higher pressures so that their cycles would be useful in temperature ranges suitable for cooling food.
Do they have air-source heat inverters with food coolers as a source and HVAC as a sink?
I almost want to read TFA...

Walgreens To Build First Self-Powered Retail Store

TheStonepedo Lighting Choices Are Not Extraordinary (186 comments)

Daylight harvesting is a nasty misnomer - it really just means turning the artificial light down when natural light makes the space acceptably-bright. This is why Walmart stores built in the past two decades have skylights.
The 2012 IECC requires daylight harvesting or separate switching for daylight zones; complying with new codes is hardly a newsworthy achievement.

LED lighting for commercial spaces just recently reached a point where lumen output, specifically illuminance at the target work plane, can equal that of fluorescent for the same power input.
With a cost roughly double that of fluorescent fixtures, LED fixtures' lamp life allows the owner to spend less on maintenance labor, with a payback on the order of 2-10 years. A company as big as Walgreens would be foolish to use anything other than LED unless they expect to go broke before reaching their ROI.

I like what these guys are doing, but the PR spin is a bit much.

Google.com.pk and 284 Other .PK Domains Hacked

TheStonepedo Re:Freehostia (35 comments)

Let's pretend for the sake of argument you are one of the good guys - I believe you, but how can an even-less-technical user be sure?
Could something be done during routing traffic in the internet at large to block port 53 for an IP address or a range of IP addresses when there is reason to believe malicious redirection is occurring?
Is protecting a mostly-non-technical majority from falling for DNS-based bait-and-switch tricks worth having to appeal an occasional false positive?

Outside of the scope of TFS:
What do you do with your DNS?

Google.com.pk and 284 Other .PK Domains Hacked

TheStonepedo Freehostia (35 comments)

Would blocking port 53 by default on free subdomains prevent such hijacking?
I cannot think of a legitimate reason one would need a free DNS server beyond those that already exist with stated goals of minimizing/preventing DNS-based censorship.

Color-Screen TI-84 Plus Calculator Leaked

TheStonepedo Re:Certified dumb for school use? (245 comments)

Dumb enough for primary/secondary school - maybe.
Dumb enough for college (or professional certification/licensure) - no way.
In courses from calculus to physics and beyond, scientific calculators without graphical bells and whistles are adequate for use with problems designed to demonstrate understanding of a subject.
If you really need data visualization use Matlb or Excel.
If you need to test for Matlab or Excel proficiency, let the students hand-write code on the exam.
It's just too easy to cheat with technology to use much of it during testing.

Ask Slashdot: Developer Or Software Engineer? Can It Influence Your Work?

TheStonepedo A Non-software Engineer Intern's View (333 comments)

If professional programmers risk revocation of their right to program in their state if injury or damage to property occurs due to poor practice, then by all means call them engineers and require them to meet state-mandated licensure requirements.
If the field of programming practiced is unlikely to cause injury or damage to property, require only clients' preferred certifications.
A skilled programmer in either position should be paid well regardless of title.
If programming was easy women and children would be doing it ;-)

Ask Slashdot: Ideas For a Geek Remodel?

TheStonepedo Re:This is the in-law's house right? (372 comments)

The parent poster is right.
Depending on the local electric utility, you might have to have current transformers and a CT meter for a big single-phase service (over 320A around here).
Unless you have a dedicated transformer with CTs and a meter base far from the house you'll end up with more ugly boxes on the outside wall.

Hiring Smokers Banned In South Florida City

Hiring Smokers Banned In South Florida City

TheStonepedo Re:Easy answer (1199 comments)

Regarding smokers being more productive than non-smokers:
Non-smokers can stay in the office while on non-smoking breaks.
If an office has flexible hours and smokers choose to come in early so that their combined work time and smoke break time aligns their quittin' time with that of their non-smoking peers they can all do the same amount of work by the same deadlines.
The smokers still take longer, in total, from start to finish.

Is your statement about productivity a suggestion that smokers are actually better/smarter/faster employees?
That seems more a symptom of a Type A personality than of a love for nicotine.

Think Tank's Website Rejects Browser Do-Not-Track Requests

TheStonepedo Re:Subscriptions? Donations? (362 comments)

That seems more a case of traditional market research into readership demographics than the targeting of individual readers suggested by TFS.
It would be a logical choice to advertise tailgate grocery specials in the sports section rather than the international news section - the opposite may be an indication of tracking and targeting.

Think Tank's Website Rejects Browser Do-Not-Track Requests

TheStonepedo Subscriptions? Donations? (362 comments)

Once a site delivering free content is popular enough to have significant operating overhead, it's probably worth the effort and money to formally organize the content provider as a for-profit or non-profit entity.
The local newspaper in my town of approximately 100 thousand sells subscriptions to readers who want more than a fixed quota of articles per month.
Wikipedia has fundraisers.
Both of these free content providers have found ways to fund their efforts without using targeted ads.
Suggesting that ad revenue will disappear without personalized ads seems to overlook the fact that many people are willing to pay a fair price for content instead of expecting ads to support their mooching.

Ask Slashdot: What Distros Have You Used, In What Order?

TheStonepedo Redhat - Ubuntu - Debian (867 comments)

The first burned CD I ever had in the late 1990s was a copy of Red Hat.
This was in the day of dial-up internet and my winmodem was either unusable or too complicated to figure out.
Installing Red Hat was an exercise in learning how to install an OS and nothing more.

In 2005 I downloaded and installed Ubuntu for fun after seeing relatively user-friendly Linux installations at the Georgia Tech math lab.
Upon dist-upgrading to Ubuntu 6.06 I found that most of my hardware, including accelerated graphics, worked without significant effort.
A couple Ubuntu dist-upgrades later I experienced a nasty regression in hardware support and switched to only using "LTS" versions for the sake of stability.

One of the recent LTS versions of Ubuntu changed the photo album software used by the default "ubuntu-desktop" metapackage, giving me the feeling that Ubuntu was more interested in keeping up with trends preferred by non-technical users than keeping functional features for nerds.
At that point I switched to Debian stable.
I have old hardware with Debian+GNOME and even older hardware with just CLI - both working smoothly with hundreds of days of uptime.

uTorrent Adds "Featured Torrents" Ads — With No Opt Out (Yet)

TheStonepedo Re:What's available for Bitttorrent clients nowada (399 comments)

Since rtorrent is a CLI program it can be run unattended in a screen instance instead of cluttering your taskbar/tray/what-have-you.
rtorrent also has Windows binaries available for download and can be installed on OS X via MacPorts.

Speed of Sound Is Too Slow For the Olympics

TheStonepedo Re:I call bullshit. (255 comments)

Most HVAC design is Imperial:
BTUs* for heat
Degrees Fahrenheit wet bulb and dry bulb for temperature
Grains per pound for relative humidity

Chances are your thermal comfort in the USA can be attributed to Imperial-unit-based "real work".

One of the first equations recent graduates learn in their practical education is:
Q=1.08*CFM*(T-T_0)
That 1.08 has units of (BTU * minutes) / (feet^3 * hours * degrees Rankine)

ASHRAE publications (engineers' bibles for heating and refrigeration design) have both IP and SI editions, but the current standard for equipment specification and engineered design is Imperial.

*or even Tons (the energy required to melt one short ton of ice in 24 hours) as a rate of cooling. One ton is defined as 12,000 BTU/hour, but in reality about 11500 BTU/hour would melt a short ton of ice in 24 hours.

Facebook API Bug Deletes Contact Info On Phones

TheStonepedo Re:Well deserved (178 comments)

Some of my business contacts are near-luddites who only communicate via phone or in-person meetings; others have faxes, email, AIM, and Skype.
Sure, Facebook has better-targeted advertisement than flyers, newspapers, radio, and television.
What does it have to outperform existing technology for real business correspondence?

You had me convinced until the "business Facebook account" bit.
I have not yet seen anything more businesslike on Facebook than advertising to employees and customers/clients coerced into being "fans".
What is the point of a duplicate personal account for business use on an ego-driven gossip tickertape service?

Use 'em or Lose 'em

TheStonepedo TheStonepedo writes  |  more than 8 years ago

Most of the time I keep up on /. enough to use moderator points. The last time they came around, however, a combination of being tired and not wanting to read the 4 most recent articles left me with points. A couple days later, the points never did anything but are gone. I like that there are so many users that my occasional apathy doesn't adversely effect the function of the site. I'll continue using meta-moderation as often as I have time, but might not moderate every round now that I've though about it some.

I saw an entry by KarmaTroll which was, effectively, copy/pasting a whole article. Although I have never found it insightful or informative but have instead found it downright annoying, I was surprised when the post was modded down. Copy/Pastes are usually dubbed informative, and sometimes stupidly dubbed insightful, but rarely shot down. Maybe the name KarmaTroll did it.

Ratings

TheStonepedo TheStonepedo writes  |  about 9 years ago I created an account mainly to write silly/funny comments. This drove my user status karma whatever the hell down to nothing. Now all of my comments that are meaningful, and some which possibly would be found funny, are rated 0. People with shallow responses to my comments get rated higher than the comments themselves. How can somebody's quoting of four of my words and writing 8 of his/her own in a response qualify as better than my well thought-out, paragraph-ish comment?
