Everybody recognizes that Adobe Flash is on the way out. It takes effort to convert existing websites, though, and some sites aren’t maintained, so it won’t disappear from the Web in the next few decades.
When it’s minor or abandoned sites, it doesn’t matter so much, but even the Library of Congress has the issue. Its National Jukebox currently requires a browser with Flash enabled to be useful. Turning on Flash for reliable sites such as the Library of Congress should be safe, at least as long as those sites don’t include third-party ads from dubious sources. Not everyone has that option, though. If you’re using iOS, you’re stuck.
I came across the National Jukebox while doing research for my book project Yesterday’s Songs Transformed, and it’s frustrating that I can’t currently use it without taking steps which I’d rather avoid. The good news is that this is a temporary situation and work is already underway to eliminate the Flash dependency. David Sager of the National Jukebox Team replied to my email inquiry:
When people who don’t understand file formats manipulate files in order to cover their tracks, they generally fail miserably. Slate magazine gives an entertaining case in point from the Trump scandals. The article says:
There are two types of people in this world: those who know how to convert PDFs into Word documents and those who are indicted for money laundering. Former Trump campaign chairman Paul Manafort is the second kind of person.
The PDF Association chimes in with additional technical details.
The Libtiff source code repository is now on Gitlab. The old CVS repository on maptools.org will be maintained for historical purposes but won’t get any updates. One reason for choosing Gitlab rather than Github is that there’s already a libtiff … Continue reading

There are new releases of VeraPDF and JHOVE today.
Libtiff 4.0.9 has been released. According to the email announcing it:
A great many security improvements have been implemented by Even Rouault.
Much thanks to OSS Fuzz, team OWL337, Roger Leigh, and of course Even Rouault.
Obligatory reminder: Don’t download from libtiff dot org. It’s many years out of date.
An Open Preservation Foundation webinar, “Putting JHOVE to the acid test: A PDF test-set for well-formedness validation in JHOVE,” will be held on November 21, 10 AM GMT (that’s 11 AM in Central Europe and a ludicrous 5 AM or earlier in the US).
At this year’s WWDC, Apple introduced a new format for still images and video. The container is called High Efficiency Image Format (HEIF), and it uses a codec called High Efficiency Video Coding (HEVC). HEIF files can store still images, video, or both at once. Apple doesn’t have proper documentation on its site, as far as I can see, but a slideshow on HEIF and one on HEVC provide a lot of information. Kelly Thompson provides a technical overview.

The ISO specification for PDF 2.0 is now out. It’s known as ISO 32000-2. As usual for ISO, it costs an insane 198 Swiss francs, which is roughly the same amount in dollars. In the past, Adobe has made PDF specifications available for free on its own site, but I can’t find it on adobe.com. Its PDF reference page still covers only PDF 1.7.
ISO has to pay its bills somehow, but it’s not good if the standard is priced so high that only specialists can afford it. I don’t intend to spend $200 to be able to update JHOVE without pay. With some digging, I’ve found it in an incomplete, eyes-only format. All I can view is the table of contents. There are links to all sections, but they don’t work. I’m not sure whether it’s broken on my browser or by intention. In any case, it’s a big step backward as an open standard. I hope Adobe will eventually put the spec on its website.
We’ve been hearing reports of Adobe Flash’s death for years. But it’s not over till Adobe says it is, and now Adobe has declared a termination date for Flash support.
Adobe is planning to end-of-life Flash. Specifically, we will stop updating and distributing the Flash Player at the end of 2020 and encourage content creators to migrate any existing Flash content to these new open formats.

Every month. W3Techs records the percentage of websites using popular image file formats. For a long time, PNG was slowly creeping up on JPEG. In the latest numbers, PNG has pulled ahead, being used on 74.1% of websites, against JPEG’s 73.8%. GIF stands at a distant third with 36%, followed by SVG at 3.8%.
Keep in mind, this isn’t the same as saying more PNG images are on the Web than JPEG images. If pages which hold JPEGs contain more of them, there may be more JPEG images even if they aren’t on more sites. Since galleries of JPEG photographs are common, this is a plausible situation.
You can see the trend by looking at the RSS feed. Unfortunately, all links point to the same URL, but if you can view the RSS preview, you can get the old numbers on a monthly basis. The web page is updated daily, which is why the numbers quoted above don’t match the June numbers in the RSS feed.
