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.

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

Search for "burr puzzles"; they are mostly made of wood and fit together similarly but have many solution combinations.

The "Codelens" feature for step-by-step program execution only works for the pre-programmed examples. If you want the same visualization for your own programs you can use pythontutor.com

What would be considered "basic" AI techniques?

Any resources you would recommend for a good introduction to AI/deep learning?

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.
