Want to put a MC68000 on an FPGA? No worries, this is easy! OpenCores has already implemented this, look here!

The license is GNU Lesser General Public License version 3, so if you have some Creative Commons Attribution Share-Alike 4.0 code, like from Steve Chamberlin’s FPGA IWM, then you can combine the whole product together under the license GNU General Public License version 3. Yeah, I know, it’s tricky, but at least it works. Yeah, and if you’re wondering about, Steve Chamberlin also implemented a Macintosh Plus clone on an FPGA, this involved writing FPGA cores for the support chips like the VIA. But, what license is that under? Since the TG68 core is under LGPLv3, this means the remainder of the whole linkage can potentially be proprietary. And since the license for the remainder is unspecified, we might as well just assume the remainder of the code is proprietary, given what we know about Steve Chamberlin.

Apple Ireland, started as a manufacturing facility, in fact their first location outside of the U.S. But pretty quickly after its founding, Apple realized the tax advantages of Ireland and built up the Apple Sales headquarters there, which is primarily responsible for handling money matters of sales in European countries. Interestingly, though for a moment I suspected Apple’s headquarters may be in Ireland like Medtronic recently did, Apple is still headquartered in the United States. It’s just that their Ireland location is a significant subsidiary.

Apple iPhones made from rejected parts? Okay, now this is pretty interesting. Wow, and the biggest fraud yet related to Apple iPhones. Really tough when you’re a company like Apple.

RTC chip showdown

2020-11-13

Categories: raspberry-pi  
Tags: raspberry-pi  

Raspberry Pi real-time clocks? Now, this is an area that is near and dear to my heart… mainly because I created an AVR firmware that replicates the functionality of the original Macintosh RTC chip. It provides both the clock function and memory. So, why can’t you do the same with Raspberry Pi? If you are designing a Raspberry Pi HAT, you should also be able to use just a single chip connected to a serial bus that provides for both clock and data. Namely, in the case of HATs, the ID EEPROM is connected to an I2C serial bus. Why not also expose your RTC function over the same I2C bus?

Sure, I’d want to reuse my firmware that I’ve already written, but alas, in case that idea is touted as “too hacky” in a larger group project, I need some alternatives. Okay, let’s go looking. Is there a good I2C RTC chip that also includes an embedded EEPROM function? There is… but not in the exact format that is expected by Raspberry Pi. These chips use I2C major address 0b1010, subaddress 0b111. Raspberry Pi expects 0b000. So, they are no-can-do without Raspberry Pi bootloader modifications, alas that’s proprietary code territory right in there, and I’m not seeing hints in the Device Tree blob used at boot.

The first chip option only has 150 bytes of EEPROM, the second has 512 bytes of EEPROM. Alas, the first is much cheaper, more available, and better supported by Raspberry Pi Device Tree Overlays, the second has a Linux driver but not Raspberry Pi Device Tree Overlays.

Looking at some of my Amazon, I notice something strange. This is paper packaging but it feels padded? Ah, they have a URL on this package for more information. Let’s see what this is all about. Apparently it is a special formulation engineered just for Amazon, this packaging may not be as widely commercially available as the older stuff.

The older kind, they call it “Jiffy packaging” when you have a paper envelope with polyethylene plastic bubble wrap inside.

The winners write the history books. That seems to be the way it always is with history. Why does it have to be that way? Well, a web search brings some interesting insight on this.

20201109/https://history.stackexchange.com/questions/5597/is-history-always-written-by-the-victors

There have been a number of times in history where the losers have written the history books. Like, the appraised cruelty of the Ottoman empire, that was due to displacement of Greek philosophers in the West. Perhaps the most significant example of history being written primarily by the losers is the Bible. Most of the life of the Israelites was under rule by some other political superior who “won” previous wars and the like, and there are very few exceptions where the Israelites were the “winners.” Likewise with the history of Christianity, until period of the crusades “sullied” that reputation.

Here is the most punctual twist on the subject in question. “History is written by those who can write.”

Okay, I’m convinced, then. Even losers’ history can be important.

Shine Studios, the video game maker? What are there wereabouts on a web search? Of course Shine Studios brings up many other different businesses that are still around. Very interesting, quite different idea and practice area though. Photography to make any ordinary girl look like a supermodel. “All women are beautiful.”

What are the essential elements that make for a beautiful photograph? There are only two that I find to be consistent: lighting and posing. Lighting should be bounce-scatter lighting of a large area light source so as to eliminate harsh highlights and shadows that exaggerate wrinkles and the like, especially on the face. Yes, I know, it’s trying to hide the real “texture” of what makes real photos real, but it’s what people like to see for human subject photography. And the posing? Well, I would have to put together a guidebook on that, that’s quite a bit more challenging.

One important point is that there is no one clothing outfit or hairstyle that is outright more beautiful than another. All variations can be creatively worked out through posing to look good, regardless of one person’s particular preferences. Likewise can be said about being out of shape, carrying extra weight, etc.

Running Saints of Virtue is difficult on modern hardware. You can start by running a Windows 98 virtual machine, but then the problem is that the high uncapped framerate makes you jump way too high, the enemies are clocked too fast, and some of your swords have way too long of a delay after firing, making the game partially playable but otherwise unbeatable.

Here’s one folk’s solution: They “cheat” by using a video capture tool that can lock the video output frame refreshing to 30fps, I’d really want to know how this works.

Also, they have a nice wiki on unpacking the game’s assets for modding and more fun.

Apparently Saints of Virtue was the only game ever released by Shine Studios, which was really just the name the two guys, Dave and Mike, picked when working on that one product. No other games were released by them it looks under the Shine Studios name.

Flip phones' comeback

Okay, I’ve seen the subject in a few random ads, now time to link to the articles. Flip-phones are making a comback… no, it’s a question, are flip-phones making a comeback? Maybe, this is the new generation of “foldables” that use a flexible screen to give a single large pane of glass that can be folded up to a smaller device that can fit easier in your pocket.

You thought there were many areas of the world that overcome COVID-19? Think again, especially in European countries. A number of key European countries called COVID-19 victory a bit too early, among the most iconic examples are the Czech Republic, Germany, and France.

In the United States, things are getting worse, but it’s not totally unanticipated. In my local area of Minnesota, for example, we never called “victory,” but we did encourage a gradual reopening at what looked like nearing the saturation of COVID-19 infections. So, what exactly is happening in Minnesota? I’d say the big thing is that we knew we didn’t have good testing early on, so we were relying on assumptions around the under-estimates from official reported cases encompassing a much larger representation of the population. Well, now we do have better testing, 40% of the state population tested, and apparently a significant number of people have already contracted COVID-19 before the recent week.
