The Ana white designs are okay for something short term but are prone to problems due to using only pocket screws and construction grade lumber. Veneered particle board would actually outlast from a construction perspective as it's less prone to expansion/contraction.

Table tops will warp if you just screw the boards together and to the base. You can avoid this by gluing the panels then attaching to base with proper fasteners to allow for expansion/contraction.

You can build them properly but this requires using true edge s4s lumber or removing the dimensional round edge with a table saw, band saw or jointer. Your glue up then requires a good number of large clamps. Even out of poplar, adler or basswood which are cheaper hardwoods you'll have $250-$300 in the table. Oak would be $500+.

>there's so much chip-board and laminating that I think there must be more plastic/glue than wood fiber. Just like electronics are being designed with obsolescence as a requirement, maybe more so is the furniture in your house

The problem is people want things cheap and nice looking. You can get a solid white oak table from Crate and Barrel for $1500; which isn't really that bad considering that's around $750 in ready to go s4s lumber from a mail order supplier. It's a lot cheaper to do as Ikea did and have a particle core with a 1/8" oak 'veneer'. Ikea's table is $600.

My first impression was that it's basically cast iron pipe designs, implemented with your custom components. Not a bad idea, especially as the pieces are more streamlined (slip in elbows) but doesn't really hit me as a real "system".

On your "about us" or product page you should do a small write-up about that actual materials and components. Basically, how is this different or better than cast iron pipe or Klee clamps?

I'd really like to know if your system can support significant weight because most of the designs (except for the garment rack) are small structures that you would expect to hold only 10-20 lbs. I would guess from the weight and dimensions of the garment rack you are using 1-1/4 OD x .065 wall aluminum round tube.

Eloquent is good if your have prior programming experience. It starts easy but the 4th chapter goes quickly to a level above what I'd expect a beginner to understand without some exposure to programming or general CS theory. The exercises include a recursive list and recursive deep comparison.

Is there room to carry personal gear/bags or is the entire cargo area filled with the supplied gear?

From a safety and security standpoint; you should probably add a true partition between the cab and cargo area. In an accident or abrupt stop the aluminum/zip-tie/mesh organizer isn't going to stop gear from coming into the cab and from the looks of it (https://i0.wp.com/campistry.net/wp-content/uploads/2017/03/I...) could probably collapse into the cab. If someone were to break in, they don't really require anything more than scissors or a knife to access the gear.

There are machines that show a physical printout to the voter but the voter does not receive the paper. It remains within the machine. I know this is the case at my polling place in Missouri. I filled out a paper ballot because two of the three electronic voting machines were malfunctioning/non-operational when I voted.

>Some DREs can be equipped with Voter Verified Paper Audit Trail (VVPAT) printers that allow the voter to confirm their selections on an independent paper record before recording their votes into computer memory. This paper record is preserved and, depending on State election codes, made available in the event of an audit or recount. -https://www.verifiedvoting.org/resources/voting-equipment/

I think this would be useful for niche applications but wouldn't appeal to contractors or anyone that didn't have very regimented tasks to perform.

The biggest problem is the payload is only 1,000 lbs in comparison to 1800-2000 for most 1500's. Many contractors opt for 3/4 ton (2500, f-250) or larger models for more payload/towing.

My brother is a contractor and has a GMC 2500 HD crew cab. It was $38k; gets ~15mpg and he drives around 35k miles a year.

Fuel for the Via truck at that milage is 30mpg, so using $3/gal would be $3500 + electricity cost versus $7,000 for gas alone.

Over 6 years the total cost difference for fuel would be $21,000 and put the gas truck cost around $60k which is comparable to the Via's $65k.

The gas truck is a better choice in this case because it has a payload of 4,000+ lbs and towing 14k+ lbs in comparison to 1000 lbs and 4000 lbs for the Via. A 1500 with a small engine would have nearly double the payload and towing of the Via and be less expensive with a higher mpg than the 2500.

The generator is cool but kind of gimmicky because the truck has to stay on site and stationary. A <$1000 generator would provide similar power and is less of a hassle than having to park your truck close enough or runs cords for power.

The numbers used seem skewed in favor of promoting their product rather than a real comparison.

The number used for MPG is 21.4 which is the "Average U.S. light duty vehicle fuel efficiency".

In addition to passenger cars the light duty vehicle class includes SUVs and pickups (including 1/2 ton models such as the Silverado, F-150). At this time I don't believe there are any electric vehicles that would compete with a 1/2 ton pickup in terms of payload or towing.

It would seem the Passenger Car fuel economy would be the most accurate number to use; which is 36.4 MPG.

They do acknowledge this number at the end of the post:

>The average EPA fuel economy of passenger cars (not counting trucks) was 36.4 miles per gallon in 2014. Using that number puts gas and electric cars on a more even playing field.

Though doing so makes electricity only cheaper in 43/50 states and the savings is not nearly as compelling as the figures from the 21.4 MPG comparison.

TL;DR: this is is more of a clickbait product promotion article than a real comparison

Forbes has an interesting article about the pricing, specifically the impact after the introduction of the competing "Auvi-Q" product.

The second page goes into detail about the rebates and discounts given to pharmacy benefit managers which partially explains the list price increases.

Re:Ask HN: What do you wish someone would build? on Saturday September 24, 2016 @01:08PM (#12571673)
You likely wouldn't save half, I would guess ~20-30% provided you do the majority of the assembly. The era of Sears homes benefitted from lax or non-existent building code (especially for electrical/plumbing).

You may also have problems selling the house in the future being it was not built by a professional. In the near term you may be unable to get financing (if you do, it will likely be much higher than a standard mortgage rate) as there is no contract or guarantee the house will be completed; they are just paying for materials.

One of the biggest costs will be the property. You need a lot zoned for residential housing with available utilities (sewer, water, gas, electric) or alternatives (septic, well, propane, wind/solar).

The lot has to be surveyed, plans approved by the building commission and permits paid for.

The foundation plan will have to be drawn up by an engineer or architect because frost depths and local regulations vary. An owner could maybe pour a slab but likely couldn't do a basement on their own; either is best left to professionals.

Now the person has to assemble the house. You could get by doing much of the work alone but would likely need a helper for various stages throughout the project.

Most of the materials are cut but you still need some tools which would be another ~$2000+ expense; ladders, air compressor, nailers (framing, trim, roofing), drills.

When it comes to the roof, especially if a 2 story house you will have no choice other than hiring a crane to set the trusses. You'd likely have to hire a crew or at least have someone experienced working with you because this part is dangerous even for professionals. After the trusses are in place you could sheath/shingle the roof yourself.

Once the shell in complete you can move inside to finish the house. This is where your local laws will make the biggest difference in price. Some will allow homeowners to run plumbing and electrical themselves, others require all work be completed by a licensed professional.

After all the systems are installed (electrical, plumbing, gas, hvac) you can start finishing the house. This part is most conducive to the DIY process as it is all aesthetic. Drywall, flooring, trim, kitchens/baths.

TL;DR -- It would still cost a significant amount and require a huge amount of labor from both the owner/builder and professionals.

Probably, just not secured to prevent people from entering. The complaint is likely that the property is a nuisance and/or hazard due to failure to properly secure the building/property (it doesn't help that the building/container wasn't permitted).

If you own abandoned property you are usually required to board up windows/doors or otherwise prevent people from entering as well as place no trespassing signs on the property.

For permitted active residential construction you can usually get by with construction fencing and no trespassing signs.

It doesn't seem like he is actively developing or living in the property; more or less just using it as a occasional getaway.

Maybe if it's the only thing you show someone but most tutorials will start with hello world! and then progress to variables, string interpolation, expressions through a sequence of:

1. Try changing the statement print your name.

2. Having to type the same thing over and over is unnecessary, we can save it in a variable.

3. You can use variables inside the print statement through a process called string interpolation.

4. In addition to strings, variables can hold many types of values, including numbers.

5. Operators can be used to manipulate values. Do some math with the variables.

6. Receive input and save in variable.

From there you can go to conditional statements, loops and functions.

I know that Team Treehouse (https://teamtreehouse.com/) has a student discount that reduces the cost from $25/month to $9.

I think this would be a good option because the courses cover a wide range of topics so she can explore computing/internet basics, different programming languages and other digital tools (Photoshop/Illustrator) before really committing to one technology.

Treehouse also has specific tracks for app, game and web development which provide a structured path to learning the technology which can be good for beginners that might otherwise be overwhelmed.

Safari Books/O'Reilly provides free access to all O'Reilly books and videos for K-12 students. The Head First series books are particularly good for beginners.

>will do a background check

In the US if you buy a firearm online from a retailer or distributor it is required that it be shipped to a Federal Firearm Licensee, who will perform a NICS (National Instant Criminal Background Check System) check prior to the transfer.

Though not required, many private sellers will only ship firearms to an FFL so that the transfer is documented (in what is called a "bound book") and the private seller knows the buyer can legally purchase the firearm.

I think the difference is that Musk basically wanted to make a mass produced electric car.

While it is difficult I would say much of this is due to the infrastructure and capital requirements to get to this point. No one doubted that an electric supercar could be made, rather that it would be very difficult to achieve scale.

Had Theranos opted for a mass produced microfluidics chip and instrument based on existing chemistries people would have said it would be difficult to compete with the large industry players (Bio-Rad, Roche, Thermo Fisher etc). This would be deemed difficult or "ridiculous" for reasons relating to capital, infrastructure and potential market share rather than the actual science and functionality of the system.

This is where Theranos differs from Tesla, not only trying to achieve scale but do so with a unproven scientific method.

It's a shame that Theranos has played out like this because a system that uses a small amount of blood is a great end goal but should have been a 10-15-20 year goal; just as Musk didn't intend to produce a $30,000 mass market car from the beginning. If Theranos built their own instrument based on existing qPCR research/design and used existing chemistry they could get "in the door" and begin really understanding the market. They would need to differentiate but could do so by attempting build a single benchtop automated unit that removed the need for manual sample preparation. While their solution may be a premium offering and a smaller market this would lead them towards their ultimate goal. Over time they could begin to look into chemistries, chip designs and instruments that would bring them closer to their ultimate goal of low cost and low blood requirement testing.

Re:Why Does a Tire Company Publish the Michelin Guide? on Thursday July 07, 2016 @08:45AM (#12048926)
It seems like "won handily" would be more appropriate. I searched within the linked book and the only result for "handedly" or "handily" was one occurrence of "single-handedly".

Surprisingly, when you Google "won handedly" (used Incognito) the tenth result is that book.

Within Google books, the query "won handedly" returns 26 results; the first being the linked book as well as another The Michelin Men: Driving an Empire.

I would assume that phrase is used in the books, but if not the text possibly an image from one of the ads?

Thanks for the clarification. Obviously the lawsuit was seeking equal access for deaf/hard of hearing individuals but had the unintended effect of removing access for everyone (public).

It's a shame that a better solution could not be reached because it was very nice having recent course videos available (as opposed to many EdX courses which use 5-10 year old videos).

Re:MIT Design and Analysis of Algorithms (Spring 2015) on Saturday July 02, 2016 @10:06AM (#12022585)
Berkeley was making all of their lecture videos available to the public until they recently moved to EdX. Course videos from Spring 2015 and prior (going back as far as Spring 2010) can be accessed here: http://webcast.berkeley.edu/series.html#c,d,Computer_Science

I have been working through the cs core classes (61a/b/c) by following the syllabus from the semester corresponding to the videos for reading and homework assignments. A google search of course number and professor's last name has been the easiest method of finding the course website (not all of them use the Berkeley course page).

Search the title, click the result. If the referer is a search engine it won't paywall you.
Re:We asked 15,000 people how they're learning to program on Wednesday May 04, 2016 @10:36PM (#11633606)
This is something that has made me hold back from applying for development positions. I like to really understand the how and why of things (and feel like that is what expected of a developer), which is why I started learning CS concepts after being frustrated following tutorials/books that just asked you to follow the specific steps for the framework.

I have done Harvard CS50 and am working through Berkeley cs61a (with the goal to then do 61b/c), the Stanford database class and reviewing maths on Khan academy. I'll likely apply for a front-end position first even though I enjoy back-end more because I don't feel like I am at the level that is expected of a back-end or fullstack developer.

Re:We asked 15,000 people how they're learning to program on Wednesday May 04, 2016 @10:06PM (#11633465)
I have been teaching myself programming and feel front end is really the only way in without formal schooling or extensive self study. "Full stack" was the most popular in the survery and I feel most code camps teach "full stack light"; enough to put up a site using RoR or Node back end/JS front end framework.

I would love to get a job doing backend development and have worked through some CS moocs and I just feel like there are so many things I don't sufficiently understand to even be considered for a backend position. I could probably handle a "full stack light" position, but get overwhelmed when I try to really understand everything going on instead of just accepting "use this gem".

Re:Just who are burner phones for anyway? on Friday April 01, 2016 @11:32AM (#11405540)
You can make any plan expensive regardless of type of phone; it all depends on your monthly data allotment, how often you want to upgrade your phone and additional services/features.

An AT&T 15gb plan with unlimited calls/texts is $115/month.

Next 12 (upgrade every 12 months) you pay like $40-45/month for an iPhone 6s. They recommend insurance which is another $8-11/month. Tethering adds $50-65/month.

I believe she would have more risk than a typical bicycle rental business because she has to assume the liability for both the rental business and the product.

If the bicycles I use for my business have defective brakes and are recalled by the manufacturer, my rental customers are at risk but some of that liability is shouldered by the manufacturer. If bikes I manufacture have defective brakes, I have to assume that liability and could be found at greater fault because I have the ability to test and recall the product.

Re:At Theranos, Many Strategies and Snags on Monday December 28, 2015 @06:30AM (#10800692)
I'd be interested to be the results from a bot monitoring/archiving the Glassdoor page. I'm sure Glassdoor has some ability to audit or approve the review statements before they posted publicly which would provide some degree of damage control, but given the negative reviews it seems some would get through.
Re:At Theranos, Many Strategies and Snags on Monday December 28, 2015 @06:23AM (#10800681)
I would think many computer scientists without a CS degree would still hold a degree in a field that would provide a solid basis for CS research (engineering or mathematics, possibly other sciences that require higher maths to be completed). There are probably a few that have little to no classical education but these exceptions are likely outliers.
