    Bigger than Apple? Although they didn't try hard. 

    Not bigger than Apple, but there are plenty of companies much bigger than RED (and Nikon+RED).

    Nikon refusing to renew patent / tech transfer for compressed Canon-RAW!

    It'll all be moot in a few years anyway when RED's patent expires.

    they never accept and will never provide scientific evidence why 24p is sacred.

    I think it's mainly tradition and what people are used to. Kind of like asking why more people like red than blue or why some people prefer LP sound.

    So, I realised that it kept failing on these files beginning with "._" I realised that they were actually there, despite Finder not showing them to me when I put it into the mode for showing hidden files, so it was only the command line that revealed their existence.  

    All UNIX, and UNIX-derived, systems hide files with names starting with "." from directory searches. You can see these using ls on the the command line with "ls -a" (or "ls -al" if you want more detail).

    If it keeps failing I think I'll look up what unix commands I can use to compare the files, I'd imagine there's a unix utility that will compare two folders and give me a nice report listing all the failures.

    Beyond Compare is what most people where I work use. There's a Mac version available.

    I tired it twice, it failed twice, and the same file is the one listed in the log as the one that gave the error.  Interestingly, that file doesn't exist, at least not starting with a "._" prefix.  There is a file there with that name without the prefix though, and it plays fine.

    Interesting. I wasn't aware of Resolve's logs--I'll have to check it out. In my case, the errors I was seeing didn't involve Resolve because I was copying files using Windows Explorer, not Resolve. The two types of error I saw, file mis-compares, and missing files, did not show up in any Windows log (as viewed in Event Viewer).

    Many Windows applications create temporary files with prefixes and/or suffixes added to the eventual permanent file name when doing certain operations on files, so perhaps Macs do something similar and that file you saw beginning with ._ was a temporary file that was later removed.

    Anyway, Fortran of today in 2024 is very different to the Fortran you'd have used back then! 🙂 

    Fortran is even a Top 20 language, in terms of popularity in the world (currently at this moment it's ranked #12):

    I didn't think FORTRAN was too bad back when I used it. The alternative (at the time) was BASIC, which was quite popular, but I never cared much for it.

    Yes, punch cards were a real pain! The basement of the computer center had about a dozen IBM card punch machines, and they were always in use during the day, so lots of people, including me, did our work at odd hours to avoid the rush. The biggest fear we had was dropping a card deck and having to put all the cards back in order.

    The first design I worked on after university was a custom bit-sliced CPU. It was microcoded and I wrote the microcode assembler in FORTRAN on a Data General Eclipse minicomputer.

    FORTRAN is still pretty popular among the scientific crowd, who use it for things like modeling dynamic systems.

  8. I learned FORTRAN in high school. It was the first high-level language I learned.

    At university, the first CS class that every CS major had to take was a FORTRAN programming class. I was an EE major, but I took it anyway as I could see that's where the industry was headed. The work was done on a CDC 6400 mainframe using punched cards.

    The second CS course, which I also took, used Pascal, which was a big improvement over FORTRAN, although even some of the CS majors just couldn't get their heads around the concept of pointers (they seemed natural to me). 

    After that, everything was in C, which is the language that I use to this day when working on microcontroller projects (as a hobby). My professional work mostly revolves around working with hardware description languages, primarily SystemVerilog, and the various tools used for simulation and verification.

    Maybe try the same drive in a different computer?

    This has got me curious enough to dig deeper. I'll try with several other computers running various operating systems, different cables, etc. Hopefully I can identify the root cause of the miscompares.

    This behaviour might have been celebrated in the US, but it outraged the general public in Australia.

    Not in my neck of the woods. When the pandemic was at its peak, county authorities ordered Elon Musk to shut down the Tesla factory in Fremont, CA. He refused at first, claiming Tesla was an "essential business" (essential businesses were exempt from the order). Public outrage and pressure from the authorities finally got him to relent. This incident is believed by many to be the reason Musk decided to move the company headquarters to Texas.

    That is bizarre.

    I happened to see a menu item in Resolve yesterday and looked it up and it's a feature where you can set a source folder and one or more destination folders and Resolve will duplicate the contents, including creating a log file in each location containing some sort of checksum, so I imagine there must be some reason they decided to implement that verification step.

    Yes, very bizarre. I've never seen anything like it in recent memory and am puzzled where the issue is happening--on the SSD itself, in the transfer process across a USB cable, on the motherboard in the USB hardware, transferring data from the USB controller into memory, a bug in the OS that's corrupting memory involved in the file transfer, or a bug in the program I use for the binary comparisons.

    I did a test yesterday that adds to the confusion. I took my newest T7, reformatted it, and copied all of my digital photos (about 1TB worth) to it. I then ran a bit-by-bit binary comparison and saw several bit compare errors and several missing files in several directories. I ran the same compare two more times and saw the same kinds of errors, but they were in different files! Yes, files that didn't compare previously were now comparing correctly, and files that compared correctly previously were now not comparing correctly.

    It's always good to compute checksums for important files to verify their integrity. They're not quite as good as bit-by-bit comparisons, because two totally different files have a tiny, but non-zero, chance of hashing to the same checksum. I think I'll try calculating MD5 hashes on all of my digital photo files from their usual location (a 10TB WD hard disk) and do the same for the copies on the T7 SSD and see if the MD5 hashes are always the same. I'll run this in a loop and log the results.

    Where the hell are the error detection mechanisms in these situations???  

    Did the OS detect the errors, or was it only your verification that revealed them?

    Only the compare revealed the copying errors. I too was shocked when I saw them and when I used Window's Event Viewer to look at the error logs, there was nothing there to indicate any device errors. The first time this happened, I wiped the T7 by reformatting it and tried the copying again, and got the same results, although the copy errors were in different files and the missing files were different. I tried this several more times with two other T7 drives and got similar results. The files being copied were about a TB of RAW files from my Canon still cameras along with associated .PSD files.

    In all cases, the drives were connected to my PC using USB C to a native USB C port on the PC. I tried four different USB cables to rule out a bad cable and it didn't make a difference.

    I tried the same tests with several T9 drives and never saw any binary copy errors or missing files. At this point, I have zero confidence in the T7.

    Any reason I shouldn't buy the Samsung T9 drive?  Pricing is not much more than the T7 and it's faster and more future-proof.

    I have quite a few of both, and the T9 is more robust than the T7. Whenever I copy files to an external SSD, I do a rigorous bit-by-bit compare of the copied files with the originals. On numerous occasions, I've found cases were there were bit errors in the copies, and even cases were entire files were not copied to the SSD. I have never had this issue with T9 drives, only T7 drives. I have seen this on several T7 drives, so it's not an isolated occurrence. It happens regardless of whether I format the drives as ExFAT or NTFS.

    This is with Windows 10 and 11. I don't know if MacOS would have a similar issue. YMMV.

    Any A6700 users here? How is overheating in practice from your experience?

    I have an A6500, so not the A6700, but the A6500 has a reputation for overheating too. I've never had a problem with overheating myself, even during our hot California summers. Big caveat, however: My "takes" are rarely longer than 1-2 minutes, so the camera has time to cool down between takes.

  15. It was an interesting year for me.

    During the late-spring, early summer I got interested in film photography again and dug my medium format (Mamiya RB67 and Hasselblad 500CM) and large format (Arca Swiss 4x5) gear out of the attic and took several trips to photograph the American West in B&W (T-Max 100). I no longer have an enlarger, so I scanned all of the negatives on an Epson flatbed scanner. That was a big learning curve, as getting good scans is not a trivial process, and it took me months to get results I was satisfied with.

    With respect to video, I upgraded my A6500 to a Canon C300 Mk3 with a few cine prime lenses. Also upgraded my tripod to a Sachtler Flowtech 75.

    I didn't upgrade any computer equipment this year as last year's setup is still more than adequate for working in Photoshop/Premiere/Resolve.

    My last video-related project of the year was re-doing all of the cabling in my home theater. It had developed into a mass of spaghetti as I added and replaced components over the years. Now all of the redundant cables are gone and the remaining ones are properly dressed and labeled.

    One thing that people often forget is that film-making is a creative pursuit and that humans are emotional creatures.  One of the critical ways this manifests in film-making is that if your equipment is frustrating to use then you will be frustrated and will not make as good creative decisions (e.g. compositions) as you might have if you were in a better mood.  If you are around people, and especially if you are interacting with the people you are filming, then your mood will alter the behaviour of those people, directly influencing the people in the frame.

    Personally, I have used cameras in the past that made me feel like I was fighting them the whole time, and I am sure the shots suffered because of it.  When I shoot now, not only do I use cameras that feel like they're helping me, but I also know that the images I get in post will be aesthetically pleasing and working with them in post will be straight-forwards, and these things make me enjoy shooting much more, making the experience nicer (which is important considering I do this for fun) but also meaning that the influence I am having on the creative aspects will be more creative as well.

    One of the reasons I prefer travelogue-style work is because I don't relate well to people in person. I attribute this to my Asperger's. I'm kind of like a milder version of Sheldon Cooper in The Big Bang Theory. I work all day with nerdy engineers like myself and most of the casual conversation is about technical subjects, not about anything related to art.

    I've always been a big advocate of using the right tools for the job. I'd rather work with a tool than fight with it, even if the right tools cost more--to me, it's worth it in the long run.

    Few actual practitioners.  It’s ok if you don’t make a living from doing this but you can tell the posters that only care and the technical process and not what it’s in service of. 

    In my case, it's only in service of my own enjoyment.

    That T2.1 lens seems to be a Zeiss CP lens in EF mount. Am I right? @Jedi Master Or what else? Did you carry a tripod along as well? Heavy Daddy and Mama, oh Papa! What made you buy the C300III over a C70? Do you regret your choice of the former over the latter when it comes to strolling the city?

    No, it's one of these: https://www.bhphotovideo.com/c/product/1629147-REG/meike_mk_ff35t21_pl_full_frame_35mm_t2_1.html

    Sorry to disappoint anyone who might have thought I wouldn't settle for anything less than a ARRI Signature Prime or a Cooke S4/i. 🤑

    Yes, we brought a tripod as well. My wife held on to the tripod while on the cable car.

    I decided to upgrade my tripod when I got the C300 and got a Sachtler Flowtech 75 CF tripod. It's lighter than my previous tripod and much easier to set up and use as the leg locks are at the top.

    There were several factors that led me to buy the C300 over the C70: Bigger and non-built-in monitor, availability of a native PL mount, CFexpress card support. I didn't find it difficult to shlep the C300 and tripod around the city. I carried the C300 by its top handle in my left hand and the tripod by it's handle in my right. My wife and I are strong hikers, so the hilly terrain of the city wasn't that big of a challenge. The cable car ride was the only physically demanding part of the day, and that was only because I was hand-holding the camera at arm's length to get a better view (and avoid getting the head of the passenger in front of me in the frame).
