I'm looking to write a program that should be capable of holding around 1000 records, each record will contain a varying number of fields and values. Usually, I'd create a list of dictionaries for something like this but wanted to know if that's the right way to go about it. This data will be routinely sorted and searched. For something of this volume, is it better (from a performance perspective) to use an SQL database or can I build an equally fast solution in Python. What does industry use? Can I get better performance implementing a different type of data …

Hi DW. Well I'm very much interested in the data protection and also giving the best privacy to the public where we protect your passwords. I've seen something that Firefox had introduced to their browsers with also their Apps. This is called LockWise which is a tool to sync your passwords with your other devices. Now as we are in the 4IR I personally think that such information shouldn't be shared purely with other devices because what will happen when you are not in front of those devices? Worst of them all we all know that browsers don't encrypts the …

Businesses all over the world are trying to figure out how to make the most of their digital marketing campaigns. The rise of influencer marketing is quite significant, and many celebrities that charge hundreds of thousands of dollars per Instagram post. However, many companies are already interested in figuring out how to use augmented reality (AR) for their future marketing and advertising campaigns. While augmented reality might not be as prevalent as some have predicted, there are still powerful corporations interested in utilizing it to their advantage. Of course, this doesn’t mean that consumers will start purchasing products and/or services …

I am thinking about making a website on a VPS. I've read on internet that if someone hacks my website and puts a malware into links or if he steals personal information(including passwords), not only hacker but the owner of the website is responsible too and a lawsuit may be opened against him/them and may pay big fines. If this is true then I really don't understand how so many people create websites and taking this risk.There may be no lawyer in this forum but I am asking to other people too, to webdevelopers(or people who want to be a …

Here is a basic question, what is the fastest way to transfer a MySQL database? Here are the variables at play: 1) Database is just shy of 3GB 2) Transfer is between two servers running different versions of MySQL 3) There will not be usage of the database during transfer, I can even shut down MySQL if needs be. 4) The database is mostly MYISAM but with a few InnoDBs and a couple Memory (VBulletin) 5) Both servers are Linux based and I have root access on both. I've done the transfer using a mysql dump, but the import took …

Haven't programmed in a long time. Last project was a GCODE pathway generator I wrote several years back. My compiler is obviously several years out of date. Uses time(), itoa(), rand(). Current standard compliant compilers should have <chrono>, <thread>, <random>, and to_string() in suppliment to those more deprecated functions. This is a very simple, high speed method of generatinga alot of randomized junk data onto your drive. Make sure you have about 300MB of RAM available for the overhead. An older non-SSD might croak. Useful for making old files unrecoverable by overwriting the old space on a drive. Doesn't go …

In the modern world, it’s easy to understand that data is absolutely essential to many corporations and organizations. There is an ever-growing need to understand the needs and desires of your customer base, so that you may tailor your products/services/platform as much as possible to meet these particular needs. However, we also are coming to a point where human beings are beginning to realize that the way that their data is being used can be quite harmful. One of the most obvious examples is the [Facebook-Cambridge Analytica scandal](https://www.nytimes.com/2018/03/19/technology/facebook-cambridge-analytica-explained.html), in which data from Facebook’s user base was used to influence a …

One of the mantras of computing and just about anything data related is "**We only lose what we don't backup**" but some are taking offense that this is still the current state of computing today. Recently some owners call this out as "blaming the user", "you're holding it wrong" or snobby. Everyone I know will try their best to help you get your machine back in working order even if people say such things. They've lost it all and upset that they can't get their stuff back. Last week's example was another smart phone, forgot their password, unlock code and …

").lower() #get name, make all lowercase alph = [" abcdefghijklmnopqrstuvwxyz"] #list of characters total = 0 #apply value for each character in name for ch in name: total = ord(ch) + total - 96 print("The numerical value of the name is \n", total) #print the result main() …

So you've lost access to your data through hardware failure or accidental erasure. What do you do? Like most cyber-warriors you naturally turn to the Internet, be that via a Google search or YouTube video, for help. That's a big mistake says [Kroll Ontrack](https://www.krollontrack.co.uk/blog/), a data recovery specialist, as self-inflicted permanent data loss is apparently on the up. Of course, there's going to be a certain amount of MRDA in this assertion. That's Mandy Rice-Davies Applies, or 'well he would say that, wouldn't he?' in case you wondered. As [Wikipedia says](https://en.wikipedia.org/wiki/MRDA), referencing an article of mine in the further reading …

Hi there, I am stuck with a problem, and don't know where to start. I need to calculate the closest pair of points on the Earth using a divide and conquer method. I know I should calculate the orthodromic distance (or in other words the great-circle distance) but I don't know what to do. This calculation has to last at most nlog(n). I found this: "The problem can be solved in O(n log n) time using the recursive divide and conquer approach, e.g., as follows:[1] Sort points according to their x-coordinates. Split the set of points into two equal-sized subsets …

I have sent raw data from a web site (with the help of jzebra applet) using ESC emulation, but when I try Svelta emulation, printer doesn't react. First question is how raw data should look for svelta emulation? Second, can it be done using jzebra applet? Best regards, Boris

What do you mean I hear you say? Well, we have some data and we have to make it look attractive (this data is a little interactive in that users will be able to interact with it, like drag and drop stuff etc). I have absolutely zero experience with visualization and I'm looking around the net for ideas. So, I was just wondering if any of …

I have Kali live with persistence and quite a few hours worth of tweaks in a bulky 15Gb USB although I'm using less than 5Gb overall. I just got a tiny, 8Gb USB memory, is there a way to migrate it all to the 8Gb one? By that I mean that the 8Gb will be fully operating with all the customizations I did to Kali inside the 15Gb USB stick. Thank you

Hey Guys, So using a webform textarea I am passing some data into PHP. This data is basically 4 columns of an excel sheet and potentially unlimited rows. Now I want to be able to go through this data, select each of the four individual elements from each row, insert these as a new row into a MySQL database and do this for each row pasted into the original textarea. I was told that Excel separates new lines with a '\n' character and each column with a '\t' separator. So my approach was to use `$rows=explode('\n',$data)` and then explode each …

Inside each link is a set of information, where an email address is located after other information. I need to make (or just find in general) something that will *open each link* and *find the email and copy it*. This sounds kinda ludacris to me, but I'm not as well informed on web scraping as you guys. The ultimate goal is to get the emails into the corresponding cell in excel (Mac, 2016).
