68 °F above average is a lot. For a tropical country it is not credible for temperatures to be that much warmer than average because the average is too high to give enough headroom. So what gives?

Reading the article I found this:

parts of Malawi saw a maximum temperature of 43C (109F), compared with an average of nearly 25C (77F)

As I expected the actual temperature increase was 32 °F, not 68 °F. So what’s up with that headline? Here’s a hint: this is what the headline might say if you set your location to somewhere other than the United States:

Now “nearly 20C” is an odd way of saying “18 °C”, but I guess they really like round numbers, and that’s not the problem. The problem is that somebody – the localization team? an algorithm? – decided that 20 °C was equivalent to 68 °F. And they’re not wrong. And yet they are.

When converting from a temperature in Celsius to one in Fahrenheit you have to multiply by 1.8 (because each degree Celsius covers a range 1.8 times as large as a degree Fahrenheit) and you have to add 32 °F (because the freezing point in Fahrenheit is 32, compared to 0 in Celsius). However if you are converting a temperature difference you just multiply by 1.8. //

This is just another version of the fallacy involved when somebody says that it is “twice as hot” when the temperature goes from 5 °C to 10 °C – note that this is equivalent to going from 278 K to 283 K, or 41 °F to 50 °F, so clearly not “twice as hot” in any meaningful way.

It turns out that, in the history of Twitter, now X, the most-liked Farsi (Iranian) language post on that platform came from a source that may surprise you - Donald Trump.

The post reportedly says in part: “I have stood with you since the beginning of my presidency and my government will continue to stand with you.”

Now, among the members of the Iranian diaspora - people who oppose the rule of the mullahs in Iran, many of whom fled the country after the Islamic revolution - are forming an "Iranians for Trump" movement. As unlikely as that sounds, it makes more sense than one might think. //

Iran - Persia - is a nation and a people with a long history. It wasn't always a nutcase theocracy ruled by Bronze Age lunatics. It was, as recently as 1979, a modern nation. It could be again. Under a Kamala Harris presidency, though, the Iranian advocates for dumping the mullahs and returning some sanity to Persia won't stand a chance. And as long as the mullahs remain in power, Iran will continue to be the world's number-one state sponsor of terror. //

People with good memory recall that Obama refused to support the Green Revolution in Iran under the guise of "no interference in internal affairs of another country" but later interfered in Egypt and Libya.

Intel’s manuals for their x86/x64 processor clearly state that the fsin instruction (calculating the trigonometric sine) has a maximum error, in round-to-nearest mode, of one unit in the last place. This is not true. It’s not even close.

The worst-case error for the fsin instruction for small inputs is actually about 1.37 quintillion units in the last place, leaving fewer than four bits correct. For huge inputs it can be much worse, but I’m going to ignore that.

I was shocked when I discovered this. Both the fsin instruction and Intel’s documentation are hugely inaccurate, and the inaccurate documentation has led to poor decisions being made. //

This will affect programmers who then have to work around the issue so that every day computer users are not affected. The developer of VC++ and glibc had to write alternate versions, so that’s one thing. The inaccuracies could be enough to add up over repeated calls to sin and could lead to errors in flight control software, CAD software, games, various things. It’s hard to predict where the undocumented inaccuracy could cause problems.

It likely won’t now because most C runtimes don’t use fsin anymore and because the documentation will now be fixed.

The Islamic Republic imposes strict rules on Iranian life. This extended photo collection shows Iranian society prior to the 1979 Islamic Revolution and, it’s obvious that Iran was a very different world.

It was also a world that was looking brighter for women. And, as everyone knows, when things get better for women, things get better for everyone. After the revolution, the 70 years of advancements in Iranian women’s rights were rolled back virtually overnight.

Wait, what? Who's occupying the White House right now, Tim? Who's been responsible for all this tumult?

A boot loop is when an Android device gets stuck in the startup screen and continuously reboots, preventing the user from fully booting up the phone. This usually happens because of a software issue, where there is a problem with the operating system that causes it to crash and restart repeatedly.

How to factory data reset an Android phone using Recovery Mode:

1. Make sure the phone is off.
2. Press and hold the power and volume down buttons simultaneously.
3. Continue pressing them until the screen starts.
4. A screen with the word “Start” pointing at the power button, text, and navigation instructions will appear.
5. You can now use the power button to make selections and the volume keys to navigate.
6. Hit the volume down button until you see Recovery Mode.
7. Press the power button to select it.
8. The phone will restart and show an Android robot in distress.
9. Press and hold the power button, then press the volume up button while still holding the power button.
10. Using the volume buttons, highlight Wipe data/factory reset.
11. Press the power button to select the option.
12. Confirm by selecting Factory data reset and let the phone do its thing.
13. Once done, select Reboot system now.

Don't put it in your pocket

Are we now going to discover that Hezbollah bought a batch of calculators from Brazil some months ago?

If they did, it's a bad move which might easily blow up in their faces.

For most of us, a calculator might have been superseded by Excel or an app on a phone, yet there remains a die-hard contingent with a passion for the push-button marvels. So the shocking discovery of an apparently rogue HP-12C has sent tremors through the calculator aficionado world.

The HP-12C [PDF] is a remarkably long-lived financial calculator from Hewlett-Packard (HP). It first appeared in 1981 and has continued in production ever since, with just the odd tweak here and there to its hardware. //

A sibling, the HP-12C Platinum, was introduced in 2003, which added to the functionality but retained the gloriously late '70s / early '80s aesthetic of the range. According to The Museum of HP Calculators, "While similar in appearance and features it appears to be a complete reimplementation by an OEM (Kinpo) based on scans of HP manuals provided by the museum." //

"Testing our rogue HP-12c, it returned a result of 331,666.9849, from a true result of 331,667.00669… giving it an accuracy [defined here as the negative logarithm to base 10 of the absolute error] of 7.2, somewhere between the HP-70 of 1974 (1.2!) and the HP-22 of 1975 (9), but far off the 10.6 achieved by the regular HP-12c and 12.2 of the HP-12c Precision." //

Not knowing about the issue at the time, Murray posted his findings on forums dedicated to the calculators – the joy of the World Wide Web is that there is a forum for everything – and after some initial skepticism, members soon weighed in with suggestions. Was this a counterfeit? It didn't look like it. Maybe the firmware was rewritten as a cost-saving exercise? Perhaps...

Some speculated that HP – or perhaps a licensee – was rather hoping that by loading up the channel with versions featuring the original firmware the problem would go away and remain unnoticed.

However, no company should reckon without the sleuthing efforts of Murray and his fellow enthusiasts when things don't seem to be... er.... adding up. ®

As long as your Android device is running on version 6.0 or newer, you have to follow these steps:

1. Press and hold the power button until power options appear.
2. Tap and hold Power Off.
3. Hold until you see Reboot to safe mode, and then tap on the prompt.

The exact wording of the prompt may vary by manufacturer, but the process should be the same. Once you confirm to reboot in safe mode, wait until your phone restarts. You should now see apps and widgets grayed out, and you will only have access to the first-party features. Don’t worry — these steps haven’t changed with Android 14.

Enter safe mode with device buttons

If you’re having issues with a laggy screen, you can also reboot in safe mode using the hard buttons on your phone. It’s just as easy to do, and you’ll have to follow these steps:

1. Press and hold the power button, then choose Power Off.
2. Turn your phone back on with the power button, and hold the power button until you see an animated logo appear.
3. Hold the Volume Down button once you see the animated logo appear.
4. Continue holding Volume Down until your device boots.
