I have created a neural network that is able to recognize images with the numbers 1-5. The issue is that I have a database of 16×5 images which ,unfortunately, is not proving enough as the neural network fails in the test set. Are there ways to improve a neural network’s performance without using more data? […]

VBSCRIPT REPLACE not removing spaces from Decrypted fields

Got quite a head-scratcher…. I’m using the VBScript function REPLACE to replace spaces in a decrypted field from a MSSQL DB with “/”. But the REPLACE function isn’t “seeing” the spaces. For example, if I run any one of the following, where the decrypted value of the field “ITF_U_ClientName_Denc” is “Johnny Carson”: REPLACE(ITF_U_Ledger.Fields(“ITF_U_ClientName_Denc”),” “,”/”) REPLACE(ITF_U_Ledger.Fields(“ITF_U_ClientName_Denc”),” ”,”/”) […]

BIND failing to query external DNS records

Unfortunately, I’m an amateur sys admin and can’t figure out what is going on with BIND (9.8). We have two old Samba servers that we use as our active directory domain controllers and therefore they are also our DNS servers. Today all of a sudden, all our external DNS requests started failing, while the internal […]

I have a drive of files recovered from a mac (hfs+) that I’m trying to copy over to an ntfs volume so that they can be accessed from a Windows machine. There are, unfortunately, quite a few files with characters that won’t copy. This is a very similar question to this one, but I’ve tried […]

Pairwise merging of files in parallel until only 1 file left over

I’d like to combine a bunch of language model (LM) count files using SRILM’s ngram-merge program. With that program, I could combine a whole directory of count files, e.g. ngram-merge -write combined_file — folder/*. However, with my amount of data it would run for days, so I’d love to merge the files in parallel! The […]

Why many Linux distros use setuid instead of capabilities?

capabilities(7) are a great way for not giving all root privileges to a process and AFAIK can be used instead of setuid(2). According to this and many others, “Unfortunately, still many binaries have the setuid bit set, while they should be replaced with capabilities instead.” As a simple example, on Ubuntu, $ ls -l `which […]
