I will be downloading this to separate download destinations and will merge them back to speed up the download. The file is really large and my ISP is really slow, so I need to get help from friends to download this in parts (actually in multiple parts)
Just to be clear I do not wish to download from multiple locations, I want to download to multiple locations. I also do not want to download multiple files (it is just a single file). I want to download parts of the same file, and I want to specify the parts that I need to download.
It does not use the zip file's central directory, which is near the end of the file. Instead, it goes from the start and parses individual local headers and skips over the payload, hoping to land at another header. It sends a new request every time it needs to skip to an offset. This of course only works with servers that support the Range HTTP header.
It takes 2 arguments. The first is the URL of the zip file and the second the file to be extracted. The to-be-extracted file's name has to be complete and exactly as it appears in the output of the previous list_remote_zip.py Python script, which it uses to get some information about the file. It then uses wget to download it at the right offset with the right length. It saves this zip "slice" to a temporary file, which is then used to output a gzip-formatted file, which can then be piped to and decompressed with gzip. The "slice" itself is not a valid zip file because it has no central directory at the end. It could be fixed with zip's -FF option but I decided to instead change the headers a little and convert it to a gzip file. Both (PK)zip and gzip use the same deflate compression algorithm and even the CRC-32 checksums seem to be compatible.
Mount the remote ZIP file via an HTTP-backed virtual filesystem and then use the standard unzip command on it. This way the unzip utility's I/O calls are translated to HTTP range GETs, which means only the chunks of the ZIP file that you want get transferred over the network.
Here's an example for Linux using HTTPFS, a very lightweight FUSE-based virtual filesystem. There are similar tools for Windows. Programming languages like Python and Java provide HTTP I/O as well, just combine them with their ZIP-reading logic appropriately.
Assuming the server supports resumed downloads it would in theory be possible to write a client that did this--grab a big enough block near the end to get the directory, then use that to figure out what you need to grab to actually get the data--simply start downloading at that position and stop when you have enough data. It's been so long since I was poking around I don't recall if there's a means of finding the start of the directory other than brute force.
I really need to print a new fan shroud. I don't have the original design for the fan shroud. A while ago, I had upgraded to B7 which was noticeably different. Apparently I deleted that download from my computer, so I tried to download the original MK3 parts, I discovered that it is truly the original version. Is there an archive of parts revisions somehwhere? I'm not ready to tackle upgrading to MK3S since that requires rebuilding the entire extruder body. I just want the fan shroud parts.
That standard page doesn't give me a link to the different versions or at least I couldn't find it. You can either choose the original Mk3 which is not what I want (it has the original fan shroud design, not what I have now), or you can do the MK3S upgrade for MK3 which also is not what I want, because it is incompatible. The GitHub link may be what I'm looking for. I previously couldn't find the Mk3 parts there.
If the specific ones you want haven't been uploaded there then you should open an issue on that project and ask for them to update with all the missing stuff. If its open source then they should update the archive.
I'm looking into working with revit duct fabrication parts. Specifically converting from design parts to fabrication parts. I've tried using the out of the box configurations/parts that come with the out of the box software with very low success, especially when it comes to fittings. My question is is there any companies out there that just sell a fully set up duct revit fabrication parts and configuration? I know the idea is to build your own but that seems like a massive amount of work.
The list Darren showed are good suppliers of content. One thing to keep in the back of your mind is if you are going to be manufacturing the duct. The database could be setup for 5' joints when you have a 6' coil line. Just an example.
I'm looking to download the score linked below with separate parts (violin 1, violin 2 etc.), but also after transposing. The website does not allow me to transpose, only the app does. When I head on to the app, I can transpose, but not download separate parts. When I use the desktop app, I have to first import the PDF, then transpose. However, the import changes the notes, key signature, time signature, and even staves in some parts. Obviously this is a pretty flawed approach.
Does anybody know how I can get the following score in separate parts, and transposed up two semitones (it was in D major, and I'd like it in E major)? It would be incredibly helpful. I have also attached a downloaded version of the full score in E major if this is helpful, but was unable to download separate parts.
You are not explaining this correctly at all. I downloaded the score into MuseScore (the desktop program), accepted the reset of positions since it was made in version 2, then used Tools->Transpose (without selecting anything) and chose the key of E. Now everything is what I expect.
Click on the download button on the website. A window will show up and give you several format options. Choose MuseScore unless you want one of the other formats for some reason. My computer is set up to automatically open these files in MuseScore, but you may need to open it yourself when the download is complete.
Plastic parts used on our 3D printers are printed by the same machines, holding on to the original idea of the RepRap project. If you want to print replacement parts or upgrades, have your printer in a different color, or modify parts, they are all available online.
To know the origin of our printable parts, the names of the parts always start with an alphabetical letter followed by a number. The identification can be found in larger parts. In smaller printed parts where the identification does not fit, dots and squares are used. It starts with a single dot, the number of dots corresponds to the serial number of the version. Squares are used for custom plastics. It starts with one square, the number of squares corresponds to the serial number of the version.
We have published STL files for every printable part of our printers, as well as printing instructions, to Printable's print depository. Here you can easily browse and view parts by their area of installation using the Printables folders feature.
We do not provide the actual project files for our printed parts. Too many different programs are being used for that. However, if you are interested in modifying the parts we have made STEP files (in addition to STL files) available on our Github, for all parts.
Some parts were designed using OpenSCAD, where SCAD files are the project files you can edit. For that reason, for all parts designed with OpenSCAD, there are only SCAD files and no STEP files available. This also includes metal parts.
If you have a question about something that isn't covered here, check out our additional resources.
And if that doesn't do the trick, you can send an inquiry to [email protected] or through the button below.
I don't have enough space on my hard drive to download the entire torrent so I wanted to download a part of it, move those files to an external hard drive, repeat until I was done. However, once I delete the files I get the "files missing" error and cannot restart the torrent to download the next batch of files. Is there a way around it?
Missing parts within a file is never a problem with modern download tools (wget, web browsers, etc). They all use multiple levels of checksums and hashes to ensure that files are downloaded correctly.
In your case, it actually looks like there we no messages published on those topics for a short period of time. rqt_bag draws a vertical blue line on each topic for each message that is published. For most bag files these lines blend together, but in some cases you can see gaps where the publisher did not send any messages (or where messages were dropped because the bag recorder was overloaded).
ok , that's interesting, I like the recorder overloading theory, because the camera always send images (why stop in the middle?), I will contact the the people that set these rosbag to make sure, .. if the error from rosbag downlaod , I will leave the question unanswered
