QUESTION
I'm trying to help a developer who is trying to harden a web server against server-side request forgery. In short, I've wrote a script that sends a "forged" HTTP request which we will use to test against the server until it is configured to not respond to such manipulated requests. I'm getting an error on Invoke-WebRequest: "Cannot validate argument on parameter 'Uri'" and while I've tried a ton of different combos of the below code I cannot get it to fly. Any thoughts? (Note: my-ef.example.com below is not the actual host)

QUESTION
Situation: I have two dataframes df1 and df2, where df1 has a datetime index based on days, and df2 has two date columns 'wk start' and 'wk end' that are weekly ranges as well as one data column 'statistic' that stores data corresponding to the week range.
What I would like to do: Add to df1 a column for 'statistic' whereby I lookup each date (on a daily basis, i.e. each row) and try to find the corresponding 'statistic' depending on the week that this date falls into.
I believe the answer would require merging df2 into df1 but I'm lost as to how to proceed after that.
Appreciate any help you might provide! Thanks!

I'm trying to create a few generic recursive types to modify structure of existing types. I can't tell why the sections inferring arrays and nested objects is not getting triggered. Any idea what I'm doing wrong?

Answered 2021-Jun-15 at 00:56Assuming what I mentioned in my comment on your question, the fix is just to simplify your FieldWithConfidence

QUESTION
In the OpenAPI docs about parameter serialization there's a short section about how to serialize query, path, header and cookie parameters with different styles. The schema of these parameters are described as OpenAPI flavoured json schema, which allows infinite nesting of objects and arrays. I haven't found any mention about how to deal with these in the docs:
https://swagger.io/docs/specification/serialization/
Let's assume the JSON schema provided for any of the parameters is like this:
...ANSWER
Answered 2021-Jun-15 at 10:35Short answer: It's undefined behavior.
Most OpenAPI serialization styles are based on RFC 6570, which provides guidance only for:
- primitive values,
- arrays of primitives,
- simple non-nested objects (with primitive properties).
In case of other types of values (nested objects, objects containing arrays, nested arrays, arrays of objects) the behavior is undefined.
Similarly, OpenAPI's own deepObject
style is currently defined only for simple objects but not for arrays or nested objects. Here are some related comments from the OpenAPI Specification authors/maintainers:
By the way, is there a reason we couldn't have
deepObject
work for arrays too? [...]Darrel: Supporting arrays as you describe was my intent. I was supposed to find some canonical implementation to use as a guideline for the behavior, but didn't get around to it.
Ron: If we end up supporting the exploded array notation, it needs to be clear that the first index is 0 (or 1, or -1, or whatever).
(source)
Ron: when we defined
deepObject
in the spec, we explicitly chose to not mention what happens when the object has several levels in it, but in our conversations we went with 'not supported'.
(source)
There's an existing feature request to extend deepObject
to support arrays and nested structures:
Support deep objects for query parameters with deepObject style
QUESTION
I am a beginner trying to teach myself C and I had a problem the other day which I thought would be cool to try and solve with a short program. I found it a bit more difficult to solve than I initially thought. Basically the problem goes like this.
I want to be able to enter a single int value between 0..255 (never outside this range) into a function, and inside the function there is an array of 8 values (1, 2, 4, 8, 16, 32, 64, 128), which can be combined by adding together to get reach the single int value. And then return the different combinations possible. i.e.
Target 192
Returns 64, 128
From what I have read this is a sub set problem and can be solved with recursion, but I am really struggling to put the theory and examples I've found into practice. If someone could help me out or even put me in the right direction to try and solve.

QUESTION
In MS Access I have a table with a Short Text field named txtPMTaskDesc in which some records contains numbers, and if they do, at different positions in the string. I would like to recover these numbers from the text string if possible for sorting purposes. There are over 26000 records in the table, so I would rather handle it in a query over using VBA loops etc.
While the end goal is to recover the whole number, I was going to start with just identifying the position of the first numerical value in the string. I have tried a few things to no avail like:
...ANSWER
Answered 2021-Jun-15 at 07:02If data is truly representative and number always preceded by "- No ", then expression in query can be like:
Val(Mid(txtPMTaskDesc, InStr(txtPMTaskDesc, "- No ") + 5))
If there is no match, a 0 will return, however, if field is null, the expression will error.
If string does not have consistent pattern (numbers always in same position or preceded by some distinct character combination that can be used to locate position), don't think can get what you want without VBA. Either loop through string or explore Regular Expressions aka RegEx. Set reference to Microsoft VBScript Regular Expressions x.x library.
QUESTION
I want to create a Google script to check if a given URL is indexed by Google, so I write the following function:
...ANSWER
Answered 2021-Jun-15 at 06:28Unfortunately doing this directly by attempting to web scrape the search results using UrlFetchApp will not work. You can use third party tools to get the number of search results, however.
More Information:I tested this out using an exponential backoff method which sometimes is able to get past 429
errors when a fetch request is invoked by UrlFetchApp
.
When using UrlFetchApp
to either web scrape or to connect to an API, it can happen that the server denies the request on the grounds of too many requests
- or HTTP Error 429
.
Google Apps Script runs in the cloud, from a set of IP addresses in a pool that Google own. You can actually see all the IP ranges here. Most websites (especially large companies such as Google) have architecture in place to prevent the use of bots scraping their websites and slowing down traffic.
Sometimes it's possible to get past this error, using a mixture of exponential backoff and random time intervals as shown for the Binance API (Full Disclosure: this GitHub repository was written by me.)
I assume that either Google directly blocks the Apps Script IP pool, or there are simply too many people trying the same thing - because with the same techniques I was unable to get any response that didn't involve entering a captcha as we discussed in the comments above and can be seen in the log of the page
string.
There are many third party APIs that you can use to do this, and I suggest searching for one that meets your needs.
I tested out one called Authoritas which returns search engine indexing for different keywords. The API is asynchornous, so can take up to a minute to get a response, so a Web App solution needs to be made.
The flow I used is as follows:
- Obtain API key from Authoritas (free)
- Create a new Apps Script project to make an API call:
