Use PowerShell to find and replace hex values in binary files [duplicate]

阅读更多关于 Use PowerShell to find and replace hex values in binary files [duplicate]

问题 This question already has answers here : delete some sequence of bytes in Powershell [duplicate] (1 answer) Methods to hex edit binary files via Powershell (4 answers) Closed 4 months ago . UPDATE: I got a working script to accomplish the task. I needed to batch process a bunch of files so it accepts a csv file formatted as FileName,OriginalHEX,CorrectedHEX.

Manipulating a JSON file with jq

阅读更多关于 Manipulating a JSON file with jq

I need to run a single command that searches an array, finds an object that has a key that equals “someData”, and then delete a key that is in the object, for example, delete a “maxHeight” key from the object where key equals “someData”. Here is an example JSON file, I would like to search the ‘tracks’ array and find the object where label =“cucumber_ChineseLong_v2.gff3” and then remove the ‘maxHeight: “200px” ‘ from that object. Is this even possible

阅读更多关于 Javascript: How to change a nodes name?

问题 For example I have this HTML: <body> <div>Text</div> </body> And I would like to change the div to something else like p . This is what I have tried but doesn't works: var div = document.getElementsByTagName("div")[0]; // Get Element div.nodeName = "p"; // Change It's Node Name to P Please no libraries, and I don't really want to replace the actual div with a new p :) 回答1: You cannot just change an element.

阅读更多关于 How do I replace the bootstrap step in the package randomForest r

问题 First some background info, which is probably more interesting on stats.stackexchange: In my data analysis I try to compare the performance of different machine learning methods on time series data (regression, not classification). So for example I have trained a Boosting trained model and compare this with a Random Forest trained model (R package randomForest).

The account shows up under Accounts & Sync along with other such accounts (Google, FB, ...). After logged in it syncs web contacts to your device. The contacts are linked to that account. They are added using batch operations using the example from the android developer webpage.
