Online file management
qdirstat for online storageLike https://github.com/shundhammer/qdirstat but for s3, dropbox etc. https://news.ycombinator.com/item?id=16189929
notepad for Dropbox / Google Drive etc.A series of Notepad For X projects. The same UI but using different backends.Insipiration:
- https://codesandbox.io/u/kjk : for editor UI
s3/dropbox/google drive client/file managerMaybe a windows/mac app. Maybe a web-based app.Main feature would be speed and search.See grokbit for inspiration.Related / inspiration:
- https://github.com/AdrianBZG/SyncMe : Dropbox and Google Drive, QT, C++, 2 pane UI
- http://cloudcmd.io : web-based, 2 pane, written in node, 2 pane UI, only for local files

a different file manager
- e each folder is in its own window, which is as small as possible
- similar to list of files in http://gotools.org/github.com/PuerkitoBio/goquery#expandgo
- can open as many folders as wishes
- each folder could be it's own window or could try to arrange them inside a single window
- handling multiple folders
- each folder is its own top-level window
- try to arrange inside a single top-level window (the problem is of intelligently arranging the pieces inside also leaves empty space vertically)
- each folder is its own top-level window but we mark all but one as participating in the alt-tab etc. and we provide an illusion they're a single group (by moving them as a group when the window is being moved)
- width can't get bigger than the biggest item
- width can be smaller than the biggest itme, in which case there are few possibilities
- use smaller font
- shorten the string by replacing part of text (e.g. middle) with "..."
- truncate right
- height can't be bigger than the total length of items
- height can be smaller, in which case do traditional scrolling
- each folder has a search box to add a filter
- content needs to auto-update
pdf inspector or text extractionshows detailed information about PDF files
PDF DRM / Protector / EncryptorA web service where peopel can upload a PDF and get a reader application for Windows that protects the PDF from being copied.It would cost between $10-$100 to protect a single PDF, unlimited distribution.Build the reader using pdfium, 32-bit only, maybe using WinForms for the viewer app.Sequence of events:
- compile pdfium library
- write the simplest reader that uses external encrypted PDF file
- write website that encrypts uploaded PDF file
faster PDF renderingFor faster PDF rendering, re-compile it. PDF format is rather complicated, mostly text format. A PDF renderer first has to parse it into in-memory representation and then renders it.Imagine a binary format that is designed for fast loading and one-time PDF => binary format compilation step. With the right format, parsing step could essentially be eliminated.We could even improve rendering time with some additional optimizations.For example, there are PDF documents with gigantic images (think 4000 x 4000 pixels) that could be resized to some reasonable value and saved in a format that is fastest to decode.I’m sure there are optimizations possible for complex vector graphics (e.g. removing stuff that we know will be invisible).
website for comparing poppler vs. mupdf vs. pdfium vs. pdf.js renderingA website that allows comparing of poppler vs. mupdf vs. pdfium vs pdf.js rendering. Upload a PDF, render each page in each engine in both native size and down-scaled to a reasonably sized thumbnail for overview. The baisc layout would be:[page 1 mupdf] [page 1 pdfium] [page 1 poppler][page 2 mupdf] [page 2 pdfium] [page 2 poppler] …Then one could click on the thumbnail to see comparison of the native size.Bonus feature: some type of overlay comparison.
html => pdfElectron (Windows/Mac) app for converting html to pdf. Sell for $29, free version can be limited to e.g. 100 free generations.https://github.com/jurgelenas/pdfify-server, https://github.com/fraserxu/electron-pdf, https://github.com/bjrmatos/electron-html-to, https://github.com/arachnys/athenapdfA textbox where users enter url, show html preview and pdf preview. Create PDF using chrome apis and allow downloading. Allow cmd-line usage. Use mupdf or https://github.com/gerhardberger/electron-pdf-window to host preview after it's generated.Advanced features would allow customizing PDF (change background, fonts etc.; works by over-writing css).
website / tool to extract text from PDFWrite a tool to extract text from PDF files.Upload the file and get text in plain text file and json (augmented with position information) and maybe even xml.Limit size of PDF files. Upsell to $19 mac/windows. Write a command-line tool, maybe even open-sources, also upsell GUI version.Good example of upselling to a better version: https://www.spyfu.com
pdf printer exeCmd-line tool for windows, based on Pdfium. Many people use Sumatra for PDF printing but printing is not great there.Pdfium should print well. Ship as a single executable which extract pdfium.dll on demand.Make it free for personal use. Make it $99 for commercial use.

web service to build a sitemapBuild a web service that builds google sitemaps (https://support.google.com/webmasters/answer/183668?hl=en&ref_topic=4581190). It crawls the website and builds .xml or .txt file with links, describes how to submit it to google etc. It should use chrome headless.It should aggressively cache the results to avoid re-crawling websites. Url should be /tools/build-submit-google-sitemap.html. Maybe use a domain like webtools.io/build-submit-google-sitemap.htmlTo make money limit web service to N links (100? 256?) and up-sell a $10-$30 windows/mac desktop app build on electron.Basically, https://www.xml-sitemaps.com but better.

awsless GUIA GUI for aws, maybe can use https://github.com/wallix/awless for the backend (https://medium.com/@awlessCLI/aws-management-simplified-awless-io-0-1-0-2ec2d8810bcb)
GUI version of https://github.com/johnkerl/miller(awk, sed, cut, join, and sort for name-indexed data such as CSV, TSV, and tabular JSON)The weakness of such cmd-line tools is that they require writing of the whole sequence of operations up-front. There are 3 problems with that:
A better approach is to allow humans multi-step refinements of data in a UI that shows the preview of the operations.For example, the operation:
- the syntax is rather arcane
- the user doesn’t see the data he’s operating on
- mistakes are costly i.e. changing the operations has to redo all computation from scratch
$ mlr --icsv --opprint --barred \ put '$tiv_delta = $tiv_2012 - $tiv_2011; unset $tiv_2011, $tiv_2012' \ then sort -nr tiv_delta flins.csvWould be done as sequence of steps
> load flins.csv $1: 215 records show first 10 records + headers > add tiv_delta = $tiv_2012 - $tiv_2011 $2: 215 records ... 10 record preview > remove tiv_2011 tiv_2012 $3: 215 records ... 10 record preview > sort by tiv_delta $4: 215 records ... 10 record preview > save flins_sorted.csv“add”, “remove”, “sort by”, “save” are operations that work on list of records. If argument is not provided, it’s implicitly the last result. The argument can be explicitly provided e.g.:
> $2 save flins_sorted_2.csv
visidata on web or desktophttp://visidata.org/ is for tabular data interaction in the terminal. Make a web version.
- Write GUI version of those tools. The simplest is a browser shell with xterm.js as front-end and just sub-launch the command and redirect output to xterm.js.More sophisticated would be tools that do the functionality but re-imagined for GUI. Implemented with web UI.

Hosted https://visidata.org/ : allow people to drop a file, run a session on the server, show it via xterm.js ui
This UI could be used for apps that present data as a stream of data that can be modified, where each modification creates a new stream, that can be inspected.
For example, a file manager-like utility:
dir "." norecur: returns a stream of files and directories, The schema is: name, type (dir or file), size, path (full path), relpath (path relative to staring dir), permissions, ext etc.
norecuris optional and disables recursive listing
size > 1 mb: creates a new stream with only items that fullfulls this predicate
ext.lower == ".png": creates a new stream where
extproperty is equal to
sort relpath, -size: sorts by name and then reverse size (biggest first)
type == file: removes non-file entries
select relpath, wc.lines: limits display to only relative path and
Properties can be chained:
dir "." norecur; size > 1 mb; ext.lower == ".png"; sort relpath, -size; type == file; wc; select relpath, wc.lines

https://twitter.com/i/moments/1133438284749840384 is a lot of zdog examples.
Improve on https://codepan.net. It's almost perfect but could use a few improvements:
- add a
/dashboardlink which lists pens (local stored in browser and those stored in a gist). This is accessible via
Homelink at the top
- improve how gists are stored (currently it's just a single json file; make it multiple files for each type)
- rewrite in svelte (just for my education)
- could remodel a bit so that github username and save button are lined with top
- could then use that as a basis for anotepad site and code eval

Could also make it into more generic visualization tool for misc system resources like processes. A quick way to make system utilities.
This is an idea for a better code browsing tool.
Have you ever flip flopped between multiple files when trying to understand a large code base?
I did, many types. Even the most advanced code browsing tools, like SourceGraph, are very frustrating when trying to understand code. The issue is this: we're not trying to understand 100 thousand lines of code at once, because that's not humanly possible. We browse the code to understand a tiny portion of a large code base but the tools are not made for that. We can do full text search, maybe with semantic understanding but when the parts of the code needed to understand a given concept spans several files, we must jump between files and loose context.
The idea is rather simple: augment standard search capabilities with a scratch buffer and add ability to quickly add parts of the code that are interesting (either by one-click add of a function / type etc. or select the code and add).
This scratch buffer allows to gather all relevant code in one place.
Write a previewer for testing notion api requests by using cors proxy cors.io and others. Simple front-end where user can pick which API to call, provide arguments and see JSON result. Inspiration:
- https://github.com/htmlpreview/htmlpreview.github.com/blob/master/htmlpreview.js for cors proxy use
- https://htmlpreview.github.io/ for nice, simple UI
- https://cors.io/ : cors proxy
- https://corsproxy.github.io/ : another cors pr
Write a tool for visualizing Go binary size. Could be web based on windows / mac app. Or all of them and use web based version to let people try the app but for heavy use direct them to $29-$39 windows / mac app.
- https://science.raphael.poss.name/go-executable-size-visualization-with-d3.html, the actual visualizer is confusing and slow

From soundcloud, nice design for showing keyboard shortcuts. Useful e.g. for comic book reader.
Better godoc. Use https://github.com/Unknwon/gowalker bettergodoc, bgodoc
Add sorting for tables. Use e.g https://neil.fraser.name/software/tablesort/
mini: write the simplest comic book reader on the web. Use https://github.com/codedread/kthoom and https://github.com/workhorsy/comic_book_reader as a base. combine with pdfvuer for PDF viewing
mini: improve the article comparing comic book readers on my website https://windowsreport.com/comic-viewer-software/
For sumatra online: https://github.com/arkokoley/pdfvuer A good starting point for view UI. It's based on pdf.js.
Ideas for improvements:
- navigation controls should be both at the top and bottom
- navigation controls should stay hidden but show up when the mouse is over them or when scrolling or when the mouse is moving (need to experiment to find out the right balance of when to show / not show)
- maybe a mini-status that shows e.g. current page number, always visible. They key is that it's small.
- full-screen option
- obviously needs more features (go to page, different kinds of layouts etc. Everything that Sumatra has
- more formats
mini: command-line sql query with all the nice ui of numeracy https://www.snowflake.com/blog/numeracy-investing-in-our-query-ui/
Nice design for showing binary structures or in sql essential book. From https://numeracy.co (now dead)
- maybe no need for
select, if we have
barare properties, then it knows it's select
- make quries live i.e. if source changes, the pipeline gets recomputed (e.g. when source is
Other possible tools like
ps: lists processes
windows: list of OS windows
- allow calling functions e.g.
boolIf a function returns
bool, it's a filter. If it returns an object, it's additional, nested properties. E.g.
image pathreturns dict with information of about an image (or empty if no information) and e.g.
image.dxis width of the image etc.
- various sys-admin-like tools like list of open tcp/ip connections, list of files opened by a given process etc.

limote - linux remote, webtermAn easier way to do linux inspection/debugging tasks.Start an agent written in Go on remote machine. It provides web-based UI either by talking to the server or to a local Electron app.
- browse, edit files
- systemd info (status of processes etc.)
- network information
- disk information
- view logs
- view (and explain) configuration
- recognize most commonly used software (nginx, apache, mysql, postgres etc.) and provide infor about them
Could start by making a server for https://github.com/yudai/gotty.Then could write a windows GUI front-end that ssh to the server and runs a command.

gui version of https://www.atoptool.nl/index.phpUse web as a front-end. Mac and Windows native apps. Backend in Go. Mac uses thin Cocoa wrapper around webview. On Windows a C# thin wrapper around cef or C++ thin wrapper around the new project from awesomium. A remote agent is copied to a linux server and the UI talks to it using some simple protocol.
desktop remote log viewerLike saw (https://github.com/TylerBrock/saw) but as a desktop app.Allows to connect to various, local and remote sources of logs and stream them locally. Add a fast search, multiple tabs, combining multiple log sources into one stream.Can stream any logs on remote ssh servers and whatever online services expose logs.Crucial for success:
- fast search in the app
- fast display. Look into xterm.js to see how they optimized text display using canvas
Remote IDELocal application where one can get browse-based shell/ide to a remote serve. Like nitrous.io or c9.io but as a local app which allows running on your own server. Works by deploying a Go agent via ssh to the server, agent talking back to local app or to the server.
BTerm - terminal/ssh client for windows or webSome ideas from DTerm: http://www.decimus.net/dterm.phpAn improved ssh terminal. Improvements:
- miniature windows for switching between terminals (instead of tabs)
- built-in file browser of the remote system
- on-the-side command execution with capture of stdout
- log all commands and their stdout, per machine (ip address)
- intellisense for typed commands i.e. remembers all typed commands and shows a pop-up with matches for the currently typed command
- support for ec2 instances

Coderunner on the webLlike http://itunes.apple.com/us/app/coderunner/id433335799?mt=12 except on the web, Go on the backend, add social features.Make it somewhat like StackOverflow i.e. people can tag a given code snippet with "Question" when it doesn't work or it doesn't behave the way they think it should. We would have a separate section on the website showing questions and basically replicate StackOverflow functionality (adding answers, accepting, uprooting etc.)Add "critique my code" section where people can post working code and ask other people to improve. Other people could submit improvements, they could be upvoted, viewed as diffs, people would earn badges etc.

> se `dir(.).where(globMatch(name, "*.Token.java")).sortBy(size).select(path)`
seis the name for the program (Shell Executor)The breakdown is:
dir(path)is a stream of files with their attributes
where(cond)is a filter that rejects items that don't match condition
globMatch(attribute, match)returns true if attribute of the item matches
matchper glob algorithm (simple file name matching). we can also provide
rxMatch()(or maybe for short just
sortBy(attribute)sorts by an attribute
select(attribute, ...attribute, ... attribute)selects only given attributes from the item
dir(".")Add other sources of data, like netstat-like information about network connectionAlternative names:
Could also make it a GUI app that would allow showing the results in GUI. The same scripts could show the results in a window.

local nfs server for Google Drive, Dropbox etc.Write a windows/mac app that allows accessing all the file storage services (Google Drive, Dropbox, S3, Google Storage, Digital Ocean Spaces, ftp, sftp etc.) as NSF. NSF because it allows user-space implementation and can be mounted on Mac and Windows.Implemented as Go NFS server and a bit of UI to provide credentials and automate mounting on the client.From UI perspective it would be better to write it as a samba server, but probably much harder.Resources:
