Real-time outlier detection from a data stream is an increasingly important problem, especially as sensor-generated data streams abound in many applications owing to the prevalence of IoT and emergence of digital twins. Several density-based approaches have been proposed to address this problem, but arguably none of them is fast enough to meet the performance demand of real applications. This paper is founded upon a novel observation that, in many regions of the data space, data distributions hardly change across window slides. We propose a new algorithm, abbr. STARE, which identifies local regions in which data distributions hardly change and then skips updating the densities in those regions-a notion called stationary region skipping. Two techniques, data distribution approximation and cumulative net-change-based skip, are employed to efficiently and effectively implement the notion. Extensive experiments using synthetic and real data streams as well as a case study show that STARE is several orders of magnitude faster than the existing algorithms while achieving comparable or higher accuracy.

            Delete selected row in DataGrid bound to an ObservableCollection
            Asked 2021-Jun-15 at 12:02

            I'm writing an app in WPF, trying to use the MVVM-design pattern (which is new to me). I have a DataGrid bound to an ObservableCollection.

            What I'm trying to achieve:

            Delete the currently selected DataGrid-row using a 'Delete'-button. I've tried a plethora of forum-posts and videos to find a solution. The solution has probably stared me right in the face several times, but at this point I'm more confused than I was when I first started.

            Any assistance would be appreciated.

            Homebrew: how to list the N last installed packages?
            Asked 2021-Jun-06 at 15:28

            Simply put: I want to list the last N packages I've installed with Homebrew.

            What is the best (and possibly fastest) way to accomplish this?

            Note that I'm not fluent in Ruby, so any suggestions to 'hack the Homebrew code to do what you want' would get me nervous...

            What I tried so far
            1. Read man pages, documentation, the Homebrew website, StackOverflow, googled with all sorts of variant questions, etc. No luck so far.
            2. brew info [formula|cask] will actually tell the date when a formula/cask has been poured (which I assume means 'installed' outside the Homebrewosphere). So that value must be written somewhere — a database? a log?
            3. Maybe there is an option to extract the poured date information via the JSON API? But the truth is that with Homebrew 3.1.9-121-g654c78c, I couldn't get any poured-date or similar element on the JSON output... the only dates that I get are related to git (presumably because they're more useful for Homebrew's internal workings). This would, in theory, be able to tell me what are the 'newest' versions of the formulae I have installed, but not the order I have installed them — in other words, I could have installed a year-old version yesterday, and I don't need to know that it's one year old, I only want to know I've installed it yesterday!
            What I learned so far

            Although I couldn't figure out how to retrieve that information, I'm sure it is there, since brew info ... will give the correct day a particular formula was poured. Thus, one possible solution would be to capture all the information from brew info and then do a grep on it; thus, something like brew info | grep Poured should give me what I want. Needless to say, this takes eternities to run (in fact, I never managed to complete it — I gave up after several minutes).

            Of course, I found out that there is a brew info --installed option — but currently, it only works with JSON output. And since JSON output will not tell the poured date, this isn't useful.

            A possibility would be to do it in the following way:

            • Extract all installed package names with brew info --installed --json=v1 | jq "map(.name)" > inst.json
            • Parse the result so that it becomes a single line, e.g. cat inst.json | tr -d '\n\r\[\]\"\,'
            • Now run brew info --formula (treat everything as a formula to avoid warnings) with that single line, pipe the result in another file (e.g. all-installed.txt)
            • Go through that file, extract the line with the formula name and the date, and format it using something like cat all-installed.txt | sed -E 's/([[:alnum:]]+):? stable.*\n(.*\n){3,7}^ Poured from bottle on (.*)$/\1 -- \3\\n/g' | sort | tail -40 — the idea is to have lines just with the date and the formula name, so that it can get easily sorted [note: I'm aware that the regex shown doesn't work, it was just part of a failed attempt before I gave up this approach]

            Messy. It also takes a lot of time to process everything. You can put it all in a single line and avoid the intermediary files, if you're prepared to stare at a blank screen and wait for several minutes.

            The quick and dirty approach

            I was trying to look for a) installation logs; b) some sort of database where brew would store the information I was trying to extract (and that brew info has access to). Most of the 'logs' I found were actually related to patching individual packages (so that if something goes wrong, you can presumably email the maintainer). However, by sheer chance, I also noticed that every package has an INSTALL_RECEIPT.json inside /usr/local/Cellar/, which seems to have the output of brew info --json=v1 package-name. Whatever the purpose of this file, it has a precious bit of information: it has been created on the date that this package was installed!

            That was quite a bit of luck for me, because now I could simply stat this file and get its creation timestamp. Because the formula directories are quite well-formed and easy to parse, I could do something very simple, just using stat and some formatting things which took me an eternity to figure out (mostly because stat under BSD-inspired Unixes has different options than those popular with the SysV-inspired Linux).

            For example, to get the last 40 installed formulae:



            Answered 2021-Jun-06 at 05:31

            The "brew list" command has a -t option:

            Sort formulae and/or casks by time modified, listing most recently modified first.

            Thus to get the most recent 40, you could write:



            Empty/blank form window in C# Empty Project (.Net)
            Asked 2021-Jun-05 at 15:34

            I need some help cause I don't know what's wrong with my new project!

            I stared a new Empty Project (.NET) in VS 2019, added same references to create form and draw different controls on it like buttons, labels and so on... Everything looks good for me and I don't get any warning/error. When I run my project it shows the form how I expected, but it's empty... no buttons or labels on the form, only the whitish coloured blank window [see picture].

            I'm not familiar with the empty projects, so probably I missed something.. I tried to type "InitializeComponent()" to the class constructor but I got an error "Error CS0103 The name 'InitializeComponent' does not exist in the current context".. I don't use the designer as this is an empty project and it's not come with it (and I don't need it!), so I suppose I don't need this method?

            Here's the code and pictures to help localize the issue.. Probably just a noob mistake somewhere but I can't figure it out.. Please help!



            Answered 2021-Jun-05 at 12:45

            I would recommend you to create a Windows Forms Application instead of an Empty project. It will be much easier to learn by sample.

            InitializeComponent is a required method. Please check the auto-generated file with comments:



            PHP Wordpress and Nginx Configuration
            Asked 2021-May-25 at 21:17

            I have something funky going on with my NGINX configuration for Wordpress. Here's what it looks like:



            Answered 2021-May-25 at 21:17

            The question is rather how you ended up with try_files $uri $uri/ /home/index.php?$args /home/index.php?q=$1; as it makes little sense in some ways.

            The $1 is used in regex capture groups, but there you have none. So indeed it will always be empty.

            The $args should be combined with $is_args which resolves to empty string if there are no arguments, and ? otherwise.

            There is only one de-facto standard construct that is applicable for many CMS frameworks including WordPress, and it goes like this:

            Second: there is a single value under /Parcare2/status, but you're trying to show it in a recycler view, which is designed to show a list of items. The FirebaseRecyclerAdapter is made to deal with a list of nodes, not a singl value as you have here.

            msvbvm60.dll deployment on Windows 10 64bit
            Asked 2021-Apr-09 at 17:37

            I created an installer using the VB6 Package and Deployment Wizard and stared testing on both Windows 10 32bit and Windows 10 64bit. The apps seen to behave as expected. Development environment includes SP6. I'm a little concerned about the deployment of msvbvm60.dll on the 64bit version. The setup program version is but it is not getting copied to SysWOW64. The existing version,, does not get updated. When I look at ST6UNST.LOG I see this:

            ACTION: SystemFile: "C:\Windows\System32\msvbvm60.dll" (File was not found or was an older version -- new file copied)

            The other files, e.g., MSCOMM32.OCX, get copied to SysWOW64 and registered.

            This does not happen on Windows 10 32Bit, The updated msvbvm60.dll exists in windows\system32.

            Anyone understand what's going on here?



            Answered 2021-Apr-09 at 17:37

            I don't think your install ought to deploy msvbvm60.dll. It is shipped as part of Windows so I think you should leave it be.

            Here's the list of files you can redistribute, if you need them.

            The Package and Deployment Wizard was probably created before the VB6 runtime was adopted into Windows. I am not sure how you edit the installer to prevent it from installing that file.

            Answered 2021-Apr-06 at 15:33

            Can't give you a C++17 answer, but since you also asked for concepts:

            The requires expression states that the () operator is overloaded and returns a bool. I think a predicate in the classical sense takes two arguments, but the concept can be easily extended to fo fulfill that requirement as well.
