I hate the invasive Dropbox client

Very hard to completely disable the Dropbox client, which sneaks its updater into every corner of my new Windows 10 system. Here’s what I had to do to finally get rid of it:

  • On Dropbox client, Settings, uncheck start automatically;
  • Disable “DbxSvc” and two “Dropbox Update Service” in services.msc;
  • Disable startups at Task Manager > Startup tab;
  • Disable services in Control Panel > Task Scheduler > Task Scheduler Library.

I want Dropbox client to update only when I run Dropbox. This invasive behavior is completely unnecessary.

Ibanez JPM weight

I’ve been searching around the weight of an Ibanez JPM, just like the P2 I own, which I have no means to weight right now. I found 4 guitars on Reverb.com, with similar measures:

  • 2000 P2, 7 lbs 5 oz, 7.31 lbs, 3.32 kg
    • nut profile, .740", 18.8 mm
    • 12th profile, .820", 20.8 mm
  • 1998 P4, 7 lbs 6 oz, 7.38 lbs, 3.35 kg
  • 1998 P4, 7 lbs 6 oz, 7.38 lbs, 3.35 kg
  • 1995 P2, 7 lbs 6 oz, 7.38 lbs, 3.35 kg

The JPM seems to be a very consistent guitar, even in the weight.

A div with a post-it 3D look

This just caught my eye while reading this thing. At first I searched for the image, but to my surprise it was all about CSS sorcery:

<html>
  <head>
    <style>
      .postit {
        position: relative;
        display: inline-block;
        width: 250px;
        border-bottom-right-radius: 36px 12px;
        padding: 15px 15px 10px 10px;
        border: 1px solid #e0dcbf;
        background-color: #fff8dc;
        margin-bottom: 12px;
      }
      .postit::after {
        content: "";
        display: block;
        position: absolute;
        width: 80%;
        height: 30px;
        bottom: 18px;
        right: 18px;
        z-index: -1;
        transform: rotate(3deg) skew(8deg);
        box-shadow: 13px 18px 6px rgba(0,0,0,0.3);
      }
    </style>
  </head>
  <body>
    <div class="postit">text</div>
  </body>
</html>

A C++ container which keeps insertion order

C++ is a poorly designed programming language, and I live a love-hate relatioship with it.

On my vacation days, when working on WinLamb for the next version of SRTEd, I needed a container to keep track of the order the elements were inserted. Among the many useless obscure things that C++ has, it doesn’t have such a container. So I had to write one, which after much struggle I named it the insert_order_map.

Usage example, including iterator support for C++11 range-based for loop:

insert_order_map<wstring, wstring> all = {
  { L"initial", L"blab" },
  { L"initial2", L"bleb" }
};

all[L"first"] = L"abcdef";
all[L"second"] = L"123456";

for (insert_order_map<wstring, wstring>::entry& e : all) {
  wstring key = e.key;
  wstring val = e.value;
}

At first I wondered about using a sentinel linear search, line the one used within store. But then I realized that 99% of the time I’ll be using a string as the key with few elements inserted, thus the initial copy of the string at each search would take away the performance gains of the sentinel algorithm. So I decided to stick to an ordinary linear search.

Avast antivirus sucks

Last month, after having had enough of Avira antivirus intrusive ads popping on my screen all day, I removed it and installed Avast. Then I started seeing my whole trusty Windows 7 x64 going slow, mainly when switching between processes, but until then I blamed the almost 8 years old computer.

That was until yesterday, while debugging C++ in Visual Studio, when I noticed an Avast DLL being loaded in the console. What the hell? It seems that Avast was somewhat injecting its DLL everywhere, making everything go slow. I immediately uninstalled Avast, and instantly my computer became fast as before.

So far I’m running no antivirus program, and I’m in doubt if I really need one. It feels a bit insecure, but at the same time so... fresh.

GitHub markdown style on Visual Studio Code

These days I found out the very useful feature on Visual Studio Code for markdown editing, which renders the MD file on VSCode itself, opening a new tab at right.

However, the rendered markdown styles matches VSCode itself. Since I mainly use markdown on GitHub, I’d like to preview the markdown using GitHub style. So I inspected GitHub and made a quick CSS file to VSCode:

Save the file and add this entry to VSCode user settings, which on Linux looks like this:

"markdown.styles": ["/home/your_name/.config/Code/User/eu-markdown.css"]

The markdown preview should be pretty close to GitHub styling now.

React Material-UI: a FAB with an optional tooltip

I’m using Material UI library to have Material Design components on a rather complex React project. Despite being good, this library unfortunately doesn’t provide a tooltip option to the Float Action Button, something I need at the moment.

I found some useful information on this project issue, and after digging into the code of IconButton – which has a tooltip option – and Tooltip itself, I wrote a component that provides a Float Action Button with an optional tooltip:

The icon is ready to be used with Font Awesome project, which is what I’m using. Other minor adjustments I made, like font size, can just be removed too. And my project requirements are web only, so that’s all I tested.
