When Twitter loads new tweets, how do I know where my last viewed ones were?

I’ve it always opened in a pinned tab in Firefox. When coming back, I see a message like “You’ve XX new tweets”. Now, if that number exceeds e.g. 10 it’s hard to remember exactly when it started filling in new tweets.

I.e. I see no visual indication that “from here on I just loaded new tweets for you”.

I’m having trouble “keeping up” to not miss any tweets because it’s just tough to remember every time where I exactly was.

Is there any help for that?

Is there a way to connect to a broker via JavaScript Paho MQTT when a page first loads and publish/receive messages despite page navigation?

I have an application with an HTML/JavaScript web UI that requires two-way communication with an MQTT broker. Using Paho MQTT I’m able to connect to a broker, publish messages, and receive any incoming messages to the console.

The problem is if I refresh the page or navigate to another screen (a different .html file), communication is lost.

Is there a best-practice way to connect to an MQTT broker when the page first loads, then listen for any incoming messages and be able to publish to the broker for the remainder of the session, regardless of any page navigation that occurs?

How to call ability of software to scale down and handle small loads with low resources

Scalability is the property of a system to handle a growing amount of work by adding resources to the system1.

But how to call the reverse quality -ability to work with limited resources provided the load is sufficiently small.

I’m asking for a good, commonly understood term that can be used to look for software with that quality. The world to type in google “X Software alternative ???”.

I believe that embedded could be indirectly related, as software running in embedded environments often need such quality, and software that can be embedded in application (like database) also usually manifests it.

One of the reasons to ask id that I’m running single personal server – and after attempting to setup ELK stack I found out I’m running out of resources on server and the log monitoring will be taking most of them. I’m not asking for recommended alternative but for help in handling similar situations down the road.

Nothing connected to the computer works after USB loads Ubuntu

Gigabyte 970A-DS3P mobo. AMD FX-8350 16g (2x8g) Windows 10 on 120g SSD I’ve tried using Rufus and linuxpen multi boot loader. With both I have tried Ubuntu, kde-neon, mint, manjaro, and puppy. All with the same result. The os opens and I know it isn’t frozen because the clock is correct. However, nothing works. No mouse. No keyboard. They’re both wired and for whatever reason they’re not recognized. If I reboot into windows everything works just fine.


Is there a way to view historical flight loads for American Airlines or other airlines?

I work for an airline and I’m able to view flight loads through a company travel portal.

What I’m looking for is historical data for American Airlines on a specific flights that flew last year. Even more public information like if the flight was sold out would be helpful.

Does anyone know of a database that keeps track of past flight information in anyway?

How best to design SSIS packages for multiple table loads

This is a question about SSIS package design.

We have an SSIS package built in VS 2008 that loads ~ 22 tables from as many fixed width files into a data warehouse. Each file has its own data flow task. All of the data flow tasks are inside a single control flow.

Would it be better to create a separate package for each table? Does the current design sound acceptable?

The package control flow appears cluttered to me, and it can take a minute or two for data validation to complete after opening the package. Correcting a problem with a single data flow means working in a package that also has all the other data flows. I’m wondering if separating it out into individual packages would make for better maintainability and readability. But, I don’t know if doing that would cause any other issues. I guess I could use guidance.

Dropped laptop – linux loads but no grub

I dropped my HP Pavillion laptop and I’m now having problems accessing windows and grub. I have ubuntu 18.04 and windows 10 installed. I was using the grub bootloader that came when I installed ubuntu. After dropping my laptop, grub will not show but (thankfully) ubuntu boots eventually. My screen stays completely black (not even lit up black where you can see it’s turned on) until I can see the ubuntu loading screen.

I tried to reinstall grub using the boot-repair recommended settings which didn’t work. I ran fdisk -l and these are the partitions detected

Device          Start        End    Sectors   Size Type /dev/sda1        2048     534527     532480   260M EFI System /dev/sda2      534528     796671     262144   128M Microsoft reserved /dev/sda3      796672 1807442666 1806645995 861.5G Microsoft basic data /dev/sda4  1910734848 1953517567   42782720  20.4G Windows recovery environment /dev/sda5  1807443968 1889363889   81919922  39.1G Linux filesystem 

I’m not sure how to proceed. I want to be able to use windows again, even if that means losing my data since I can’t afford to buy another copy and I’m using the one that came pre installed on my laptop so I don’t have any CDs or such for it. I don’t have an external hard drive to be able to back up my data. Any help would be deeply appreciated.

Site loads very slow

When you go to my site https://www.uitverkoop.tips, it will take 10 seconds before you are on the site. How can this be?

When you are on the site, and you go to different page, it loads normal.

So where is the fault? How can I fix this? It is made in magento 2.

Ubuntu 18.04 loads to wrong TTY

I installed Ubuntu 18.04, it was working fine and then an application stopped working. So I reinstalled it and upon booting the background with no mouse or icons appeared. Shortcuts worked. I reinstalled Ubuntu 18.04 again and the problem persisted. Luckily, I figured out that I can just Ctrl+Alt+F2 into the desktop environment and everything works from there.

I’m just curious about what’s going on.
