    Spell checker

    Interesting, I only see my browser's default behavior. There is a spell checker plugin for the editor they used, but I don't see any references to it in the JS when searching in the debug console (F12). And I don't have the svc.webspellchecker.net domain blocked.

    subscripts/superscripts

    I don't see an option for it. For some characters there are unicode options: all numerals, plus, minus, parentheses, and some letters: ⁰¹²³⁴⁵⁶⁷⁸⁹⁺⁻⁽⁾ⁿ ₀₁₂₃₄₅₆₇₈₉ₐₑₔₕᵢⱼₖₗₘₙₒₚᵣₛₜᵤᵥₓ We can also just type out LaTeX in code blocks. $\int_{a}^{b}f^{\prime}(x)dx=f(b)-f(a)$ It'd be much nicer if the...

    Overriding the layout to be more compact, or any other changes

    Install the Stylus extension (there are links on that page for the Mozilla Firefox addon page and the Chrome web store). Then in the extensions menu (probably under the "hamburger" menu in the browser) open Stylus. Add a new style, set it to "URLs starting with" instead of "Everything", put...

    Optimizing Performance in Embedded Systems Development - Emmanuel Katto Uganda

    Step one of optimization is finding what to optimize. Usually via profiling of some sort. You profile, find a bottleneck (in code size, RAM use, CPU cycle use, cache use, I/O use, power consumption, or some other metric), and then work on changing the algorithm used to improve that bottleneck...

    Overriding the layout to be more compact, or any other changes

    Since I'd buried it in a thread before, and it could be helpful but is easily missed: First, there are "Style chooser" and "Change width" buttons on the bottom of the page. These might be sufficient for your needs. If not, you can use CSS (Cascading Style Sheets) and/or ECMAScript to override...

    Can we PLEASE go back to the old forum!

    A great thing about the web is that styles can be controlled by the user's browser. The user (you) are in control, if you want to be and know how. I like the Stylus extension. It allows changing the styles of the site, and is a lot less complex than a more complete override system like...

    Boeing again pt2.

    Yet another Boeing 702MP satellite has broken up in geostationary orbit. After the one in 2019 that's 2/7 launched that have broken up in orbit.

    Boeing again pt2.

    DEI is just a politically correct way of saying "stop breaking the law, assholes". It's illegal to discriminate in hiring for or against any protected class (including race & sex). Lots of companies, intentionally or not, were breaking this law. Either through illegal affirmative action...

    Boeing again

    > Three separate, well-placed sources have confirmed to Ars that the current flight software on board Starliner cannot perform an automated undocking from the space station and entry into Earth’s atmosphere. ... Regardless, sources described the process to update the software on Starliner as...

    Baltimore Bridge collapse after ship collision

    Ohm's Law (for real power): E=IR. E is electromotive potential (voltage), I is current, Z is impedance (resistance + reactance). Frequencies are low enough we can pretend it's DC and use resistance in place of impedance. Breakers trip when current exceeds some value for at least a minimum...

    I-195 Bridge Closure, R.I.

    Sure, I'd expect a *lot* higher costs in practice. I only calculated the energy needed to *melt* that much snow, not to prevent ice forming when it's cold out, or to heat the road itself, or the cost of the heating elements themselves, or the cost of replacing the elements every time a road crew...

    I-195 Bridge Closure, R.I.

    The enthalpy of fusion of water is 333.55J/kg. US lanes are at least 3.7m wide, fresh snow density generally varies between 50 and 200 kg/m^3. Ignoring shoulders, that means 620e3J/km/lane/cm_snow to 2.5e6J/km/lane/cm_snow. Equivalently 0.17kWh/km/lane/cm_snow, 0.69kWh/km/lane/cm_snow. According...

    SpaceX foundation slab pulverised

    Scott Manley's analysis is good. Rapid unscheduled digging threw concrete around, which destroyed several engines. The others that failed may have also been damaged, and just took longer to completely stop working. The rocket lost (at least some) attitude control, was too low to separate, and...

    Train crash in Ohio

    > The whole federal governments attitude seems to be that it is a red state, so it is not important. > I guess we should call the present administration the blue state government. The actions the federal government can (legally) take without the governor issuing a declaration of emergency are...

    E-scooter and E-bike fires

    UK plugs make the best caltrops. They're huge and most stable with the prongs facing straight up, unlike other plugs that tend to lie with the prongs horizontal. Perfect for "Home Alone" style misadventures. They do have some good things for electrical safety: the long ground pin and shrouded...

    Thanks to the International Yard and Pound agreement, the US inch is defined to be exactly 25.4mm. The US Gallon is defined as 231 in^3, and the oil barrel 42 gallons. The mm is defined as 1/1000 of a metre. The metre is defined as "The distance travelled by light in a vacuum in 29979458^-1...

    KN-95 vs N-95

    I agree with Zeusfaber. I took to wearing a P100 respirator, with the exhalation valve covered in a surgical mask. Just as safe for everyone else as surgical masks (better than cloth), both safer and more comfortable for me. Edit: and it has the side benefit that I never have to smell cigarette...

    A good lawyer is (in general) necessary but not sufficient to be found "not guilty" of a crime you didn't commit.

    BBC: Massive Toxic Chlorine gas leak at Jordan's Aqaba port kills 13, injures hundreds !!!

    Dulce et Decorum Est By Wilfred Owen Bent double, like old beggars under sacks, Knock-kneed, coughing like hags, we cursed through sludge, Till on the haunting flares we turned our backs, And towards our distant rest began to trudge. Men marched asleep. Many had lost their boots, But limped on...

    US Navy litoral combat ships having engineering failures

    AFAIK the big problem with the A10 is MANPADs (Stinger missiles and the like) and other SAMs. It's a very durable aircraft, but it's also a very easy target to hit. The F35 is worse at the job of close air support (CAS), but (at least in theory) it's much harder to lock onto & hit than an A10...
