Atkinson's HyperCard was released in 1987, before the widespread adoption of the web. HyperCard introduced concepts like interactive stacks of cards, scripting, and linking, which were later adopted and expanded upon in the web. Robert Cailliau, who assisted Tim Berners-Lee in developing the first web browser, was influenced by HyperCard's hyperlink concept.

> There is no performance benefit that immutable structures offer that cannot be had by mutable ones. It is asinine to assert otherwise, especially when literally every single measurement ever done demonstrates that immutable structures perform orders of magnitude slower.

Copying is free. Comparisons and change detection are much faster. Data-sharing, thread-safety, content-addressing, versioning/persistence have faster and more efficient implementations--often for zero cost. Immutable data structures have more guarantees, which lend themselves to more optimizations.

Chart parsing uses immutable data structures and many other DP algorithms rely on immutability to take an algorithm from exponential running time and space to polynomial running time and space. Git uses content-addressing to implement zero-cost branches, which used to be inefficient in traditional version control systems, which were more imperative.

Linked lists were heavily used in application software before the appearance of standard libraries and Java, which is when dynamically sizable array-based lists become common. There also wasn't a gap between the performance of linked lists and arrays before CPU became significantly faster than RAM.

If it is 23M pixels per lens, that is still more resolution than a smartphone's screen. Each lens is smaller than a smartphone's screen and the resolution is per eye. I wouldn't be surprised if this actually exceeds the eye's ability to perceive pixels.

The difference between a monitor and the lens of a headset. If you look at a 4K monitor up closely within a region of the screen of two inches in radius, you are not seeing 4K in that region. 4K of pixel applies to the whole monitor not to the eye's field of view as it does to a headset.

If you were using the headset as a monitor, you could zoom in on text and the text can effectively have infinite resolution as it scales up into view.

This post is not valid because most companies post jobs in Hackernews after several days. In addition, the is-hiring post opened on April 3, 2023--a little over 24 hours ago.

As other people have noticed, April appeared to be the lowest month in new jobs, but the true numbers won't be evident until the month is over. The ratio will likely fall lower with the reasonable assumption that a greater proportion of people seeking work post earlier in the month than of companies seeking employees.

> If you were starting a startup for example, you wouldn’t need to hire any humans - you would just spin up enough AGI instances and they would design your product, write your code, deploy it, handle your financials, respond to any and all customer interactions, proactively navigate regulations and litigation, and everything else that needs to be done in the management of a business. That is the goalpost for AGI. It’s an artificial human - a human replacement.

I disagree with the premise. A single human isn't likely to be able to perform all these functions. Why do you demand GPT-4 encompass all activities? It is already outperforming most humans in standardized tests that rely only on vision and text. A human needs to trained for these tasks.

It's already a human replacement. OpenAI has already said the GPT-4 "with great impact on functions like support, sales, content moderation, and programming."

The sequence that you get from the difference of successive numbers in the list is rather predictable: 1,2,3,4,5,6,7, ...

Former Excel 97-XP developer here. Excel 97 had English language formulas. It automatically detected names in tables; however, it was buggy. The feature was removed in a later version (2007?).

C# had value types and pointers from the very beginning. These are not a recent addition. The standard library does know about them. However, not until C# 2.0, which introduced generics, were collections able to avoid boxing value types.

There are some cases where allocations are made when they could have been avoided. Iterating over a dictionary creates a single IEnumerator object. Async methods, tuples, delegates, and lambda expressions also allocate memory as do literal strings. It is possible to have struct-based iterators and disposers. There are some recently added mitigations such as a ValueTask, ValueTuple, function pointers, ref structs, conversions of literals to read-only spans, that eliminate allocations.

DateTime is a value type and doesn't allocate memory. Getting the current time does not allocate memory.

With the recent additions to ref types and Span<>, C# provides a lot of type-safe ways to avoid garbage collections. You can always use pointers if need be.

Git IS heavily used outside of software engineering.

Marketers and documentation writers use markdown and git for building websites and books.

Data scientists use git for their notebooks.

Operations use git for their deployment scripts.

Git isn't the best for office documents. Revision marking (aka, change tracking), document comparisons, and merging are all available in Office suites. Git isn't really used here because there features predate Git, operated on binary files or complex XML documents (neither of which are conducive to diffs).

Git isn't good for databases or data lakes. The files are huge and typically aren't modified (CSV) or are binary/compressed (Parquet).

Former Excel developer here. In Excel 97, the difference between the values needed to be less than 1e-16 times the magnitudes of the operands to be considered equal. It makes sense since such a small proportion is unlikely to occur by chance through arithmetic without the values being "equal" in the original base.

Fact check: The cost of S3 standard storage per TB is approximately $23 not $153. S3 standard storage, the most expensive kind, is $.021-.023 per GB.

S4 costs about the same as S3 Deep Archive storage.

Update: The article appears to be a joke. That aside, there are no cost savings against S3 Deep Archive; additionally S3 Deep Archive supports restores unlike the write-only S4.

The sounds were loud and lasted several seconds. These were removed because most computing devices are now mobile. The sounds are extremely annoying and disruptive to hear from a stranger's laptop every few minutes during a meeting, a classroom lecture, wifi shop, cubicle environment, auditorium, airplane, etc... They could also be embarrassing to anyone who just revealed that they were not paying attention.
