Difference between state and State
- Although this kind of design serves several proposes, in special on more simple or data-centric scenarios, in fast evolution and process-centric domains it evolves on a mess of code execution paths and unsynchronized conditionals through different functions.
- The problem faced here is that the application architecture allows for invalid behavior through invalid states, and when it does eventually some use case will expose the bugs created by this freedom.
- The entity, represented as a state machine, is now just a different data structure for each State that can be interpreted by the pure functions that implement the domain behaviors.
- It is true that many domains can be modeled using the two first approaches to code a State, but sometimes we are faced with a high complexity scenario where this abstraction implementation would not scale with the development of the application.

Amazon is selling a Kindle Paperwhite and Audible bundle
- Last year, Amazon began adding Audible to its Kindle Oasis, the entry-level Kindle, and the latest Paperwhite, allowing users to listen to their audiobook library, provided they had a set of Bluetooth headphones.
- Now, Amazon is selling an Kindle package that includes a Kindle Paperwhite, a set of Bluetooth headphones, and a three month trial for Audible.
- The Good eReader spotted the deal, which will run you $139 for the 8GB Kindle, and $179 for the 32GB model.
- The package comes with the latest Kindle Paperwhite model, as well as a set of Amazon’s POP Design headphones — which Good eReader points out retails for $79 on their own.
- The deal also comes with a starter subscription Gold Membership for Audible, which will provide you with three free credits in the first three months.
The best mouse pads you can buy
- A smooth, tactile surface is still a necessity — even with the greatly enhanced sensitivity and accuracy of optical mouse sensors — whether you're doing precise tasks like graphic design and gaming, or just tackling another long day of working on the computer.
- When it comes to pad surfaces, there's a general trade-off between speed and accuracy: Softer or rougher textures will create more friction than a hard, slick surface, allowing for more precision (as well as creating more drag), whereas a smoother mouse pad will allow for quicker movements (such as while playing a fast-paced video game, for example) at the cost of accuracy.
- Unless you specifically want the increased movement speed of a hard working surface, then soft mouse pads are generally the best option for most people, especially if you're sitting at a computer for extended periods of time.
Start using asserts!
- An assert, if you happen to not know, is a statement that must be true or the program does a predetermined action, usually exiting the whole application.
- For an example where we could use an assert, let's see how we initialize SDL2.
- In SDL2, a function called SDL_Init() that takes flags OR'd together and returns a value.
- SDL2 also provides a function called SDL_GetError() that gets the error message from the most recently failed function.
- Wouldn't it be nice to have something to check the result and print an error message before exiting?
- In C++, there are macros provided by the standard/compilers called __LINE__, __func__ and __FILE__ that we will use for this purpose.
- We'll have to modify the macro where it fills the arguments of a function that we will create in a moment that does the actual work of printing the message along with the other information and exit.
Great Adventure-Game Puzzles
- (Small wonder so many hackers have found text adventures so appealing over the years!) First comes the great mental leap of connecting these four disparate elements which you’ve found scattered about: an empty maze, a book of legends, a map, and a pencil.
- It demands a parser capable of understanding a construction as complicated as “draw line from H to P,” a game engine capable of re-jiggering map connections and rewriting room descriptions on the fly, and even a measure of artificial intelligence, including a path-finding algorithm, for the Terror.
- Why it works: This is easily the most famous text-adventure puzzle of all time, one whose reputation for difficulty was so extreme in the 1980s that Infocom took to selling tee-shirts emblazoned with “I got the babel fish!” In truth, though, its reputation is rather exaggerated
A month of Flutter: no content widget
- With any sort of content site, there is always a chance of having nothing to display.
- For this view I'm using an illustration from the amazing unDraw site.
- I've choosen the SVG version as it's small, scales to any device size, and is easy to change the color of if themes are implemented.
- The main goal here is to render the SVG with some text underneath it.
- Since nothing in NoContent is going to change, let's give it a const constructor.
- We'll also make it so the Column contents are center aligned vertically and that the Container takes up the entire view width.
- With NoContent implemented, we'll just swap it into the Scaffold body for rendering and update the tests accordingly.
- The size and spacing of everything will have to be adjusted as the app design evolves but this is a good base implementation.
A day in the life of a luxury interior designer, who starts her day with a 'caffeine cocktail,' has designed homes for Chrissy Teigen and John Legend, and goes to a SoulCycle class every night
- In sharp contrast to the many executives who wake up at 4:00 or 5:00 a.m, Eisen starts her day slowly, waking up at 9 a.m. and enjoying a "caffeine cocktail" of Poland Spring water, espresso, Truvia, and Lactaid milk.
- Eisen, 50, is the CEO of Interior Marketing Group, or IMG, a New York City-based company of nearly 80 employees that does interior design, staging, and marketing for luxury homes that start at $5 million.
- Eisen has done the interior design for apartments in buildings belonging to Ivanka Trump and Jared Kushner, an Airbnb rented by Kim Kardashian West and Kanye West, and homes for Bethenny Frankel, Swedish real estate broker Fredrik Eklund, and Chrissy Teigen and John Legend.
- Eisen said IMG's designs tend to be neutral and classic.
- Here's a peek into a typical day in her life, from her morning "caffeine cocktail" to rearranging furniture and choosing drapes for multimillion-dollar New York City penthouses.
25 Microchips That Shook the World (2009)
- The breakthrough, says Bill Mensch, who created the 6502 with Peddle, was a minimal instruction set combined with a fabrication process that “yielded 10 times as many good chips as the competition.” The 6502 almost single-handedly forced the price of processors to drop, helping launch the personal computer revolution.
- The big state of Texas has given us many great things, including the 10-gallon hat, chicken-fried steak, Dr Pepper, and perhaps less prominently, the TMS32010 digital signal processor chip.
- “That made program development [for the TMS32010] flexible, just like with microcontrollers and microprocessors,” says Wanda Gass, a member of the DSP design team, who is still at TI.
- Some 6 billion have been sold, used in things like industrial controllers, unmanned aerial vehicles, digital pregnancy tests, chip-controlled fireworks, LED jewelry, and a septic-tank monitor named the Turd Alert.
The 30 best pairs of sneakers to give as gifts this year
- The unique design strips away unnecessary elements of a shoe (like a midsole) by sitting the Flyknit upper directly on top of large sectioned Air units.
- If you're shopping for someone who likes luxury and classic style, Greats is one of the best places to get a sneaker gift.
- Lacing them up for a game of basketball like Chuck did might not be the best idea today, but the shoe's long-lasting style makes it a timeless gift.
- Originally designed for tennis legend Stan Smith, the low-cut silhouette features a simple white leather upper, perforated Three Stripes branding on the side and his face on the tongue.
- Originally named the Air Max III, the Tinker Hatfield-designed running sneaker became known as the 90 because of its 1990 release date.
