Why testing is important even for UI design
I was gonna post this on my Linkedin by decided against it, trying to keep it professional, ya know.
“Invalid Location” error when trying to add SynoCommunity Repo
I presume you’re here from Google, trying to find a solution on why Synology DSM is not accepting SynoCommunity‘s repo, returning a cryptic “Invalid Location” error. You’re probably running DSM 6.2.4 or older, and currently unable to upgrade to DSM due to uh, various considerations (*cough*xpenology*cough*).
Turns out it’s a SSL error, not sure if it’s related to Let’s Encrypt’s root certificate expiring a few weeks ago knocking out a sizable chunk of the web, but thanks to @publicarray over on SynoCommunity’s Discord, we have a solution
Here’s the SSH command for your convenience:

A few weeks ago I made the mistake of joining another UK Project. Today I finished my voluntary withdrawal from the project, and not on a good term.
Read MoreChoosing a cloud hosting provider: Digital Ocean vs Linode
I’m gonna make this short: avoid Digital Ocean like the plague.
As you know, my whole website used to be hosted on a VM Instance on Google Cloud Platform. However, the cost of GCP was a little much for my usage so I was looking to migrate to another provider. The most obvious names that comes to mind that wasn’t ‘Big Tech’ (AWS, Azure, Alibaba, Google) are the holy trinity: Digital Ocean, Linode and Vultr (which I didn’t test).
Among those, Digital Ocean is probably the most well known name.
They’re everywhere.
They seem to have the best UI among the cloud provider (and I’m a sucker for good UIs).
They have a pretty extensive knowledgebase that covers pretty everything in tech.
They have a huge marketplace, pretty much every self hosted project you see has a ‘Deploy on Digital Ocean droplet’ option.
DO sounds like a no-brainer. So I set out to create my account. Being a skeptical, naturally I sign up using a ‘trial’ account that offer a $100 credit for 60-day, there’s plenty of those on Google if you search for it, but don’t make the same mistake as I did, the 60-day $100 is a goddamn lie. When I added my credit card, I was told there might be a $1 charge for verification that will be refunded in no more than a week. When I added my first droplet, I was immediately charged $6.15, and I’m pretty sure it’s never going to be refunded as a few weeks have passed.
This shady practice alone should be enough of a reason for most of you to avoid DO. And if that wasn’t enough, there’s also the performance issue.
I created a nano droplet (the $5/m variant). You may ask why I decided to go for the bottom of the barrel choice even though I have $100 in trial credit. In my opinion, a service is only as good as its bottom line, and testing it should give a pretty good overview of the quality of the service being offered. And boy was that the correct decision.
Performance was good on the first day, but it only goes downhill from there. I have a total of 6 WordPress websites with virtually no traffic (only one of them has like 100 visits per DAY). And yet the droplet was slowed to near unresponsive level when I finished migrating my 4th website. SFTP would constantly timeout. If I try to visit 2 of my sites at the same time, the server would return a 504 error. It was unacceptable.
I was ready to give DO the benefit of doubt and blame the disruption of AAE-1 international internet cable line as a factor (even though the droplet I created was provisioned on the Singapore data center, which shouldn’t have been affected by that incident.
It was then that I decided to make an account on Linode and give it a shot. The sign up process was exactly the same but they didn’t even charge me a cent for verification. I fired up a $5 linode, going through the same migration process, and lo’ and behold, everything just worked! All 6 websites up and running without a hitch. The hardest part of the migration was, ironically enough, caused by Digital Ocean. As the websites keep timing out when I try to create Duplicator packages.
Normally to save space on the droplet I’d make Duplicator send the packages to my Google Drive and my OneDrive Business storage, however on the DO droplet, they couldn’t even communicate with either Google or Microsoft server at all, forcing me to SFTP in and painfully try to download the package manually, bit by bit (thank god WinSCP can do that without poping up a dialog ever 5 minutes). The failure to communicate with Google and Microsoft’s server is a testament that the connection problem was with Digital Ocean and not with my ISP.
Anyway just wanted to share my experience. Obviously I’m not endorsing either Linode or Vultr yet since I’m only on a trial run with them, but one thing is definite: avoid Digital Ocean.
That’s all for today, folks.
Enhancing OpenMediaVault’s sidebar
Replaced Rockstor with OMG on my little ChocolateBox NAS. At first glance it appears to be better than Rockstor in pretty much every way except the front end. As a designer I’m always greatly bothered by subpar UIs, even those belonging to FOSS. Just spent an hour or two reimagining this part of OMV if it was created with a more modern design language:
Install Photoshop CC on Linux
No, this is not GIMPShop or any other dirty hacks that attempt to make GIMP/Krita look or feel like Photoshop. This is the real Photoshop. And no, Adobe hasn’t changed their mind about making a native Linux version available either. As you may have guessed, despite the fancy new splash screen, this is just Photoshop CC running on Wine, but it has been repacked so the installer does everything for you. If you already have a PS + Wine in place there’s no need to read this.
Bits of warning though, I’m not entirely sure this is legal since the authentication part appears to be bypassed also. While I do have an active subscription to Adobe CC, I haven’t been able to find a way to sign in with this. If this repo gets popular Adobe might kill it, so just keep that in mind.
Anyway, you can find the instruction here in this Github, I’m not going to mirror the instruction in this blog post (unless the repo goes down for some reason, in which case, let me know in a comment below)
Apt-get update chậm như rùa? Hãy chuyển sang dùng mirror trong nước
The following post content will be written in Vietnamese since it addresses a specific problem that only affect Ubuntu users currently residing in Vietnam
Mấy ngày hôm nay mấy anh em dùng Ubuntu như tôi chắc khốn khổ vì chạy cái apt update cũng phải mất cả nửa ngày. Lí do thì vẫn như thường lệ, cá mập cắn cáp AAG, chuyện năm nào cũng xảy ra đều như vắt chanh mỗi năm khi đất nước có ngày hội lớn. Chúng ta bất lực với cá mập nhưng không có nghĩa chúng ta không có cách khác để giải quyết. Nếu các bạn check danh sách mirrors của Ubuntu sẽ thấy VN là 1 trong những nước có tương đối nhiều mirrors với 9 cái:
Điều này có nghĩa chúng ta hoàn toàn có thể sử dụng mirrors trong nước để gia tăng tốc độ cho apt. Trong những phiên bản gần đây của Ubuntu chức năng tìm mirror đã được build luôn vào trong apt get nhưng ko được enable mặc định. Vì vậy để enable features này chúng ta cần thêm những dòng sau vào file /etc/apt/sources.list
deb mirror://mirrors.ubuntu.com/mirrors.txt focal main restricted universe multiverse
deb mirror://mirrors.ubuntu.com/mirrors.txt focal-updates main restricted universe multiverse
deb mirror://mirrors.ubuntu.com/mirrors.txt focal-backports main restricted universe multiverse
deb mirror://mirrors.ubuntu.com/mirrors.txt focal-security main restricted universe multiverse
(Lưu ý VD trên là dành cho Ubuntu 20.04, nếu các bạn dùng Ubuntu bản khác thì nhớ thay thế code name focal bằng code name của version tương ứng Lucid, Precise etc.)
Chạy lại apt update và chứng kiến sự thay đổi kinh hoàng trong tốc độ:
Setup a family printer with a Raspberry Pi 1, CUPS and Canon LBP 2900
Ok so after using it as an Media Server (OSMC, Kodi), Audio Server (Volumio, Moode), and most recently a CloudFlare DDNS updater on top of Raspbian Lite, I’m running out of things to do with my old RPi. I figure there’s one thing I haven’t tried turning it into: a print server. So that’s what we’re gonna do today.
Now this is actually one of the most common usage of the Pi so there’s already plenty of guides out there, and there’s really no information in this post that can’t be found elsewhere on the Internet, but I’m gonna do a write up anyway, purely for the sake of documenting my process.
For the software we’ll be using CUPS running on top of Linux, naturally, since we don’t have a lot of options on that front. For the hardware, we’ll be using a first gen Raspberry Pi for the print server part, and Canon LBP 2900 for the actual printing.
Now this printer is interesting really, because despite being one of the most popular printers here in Vietnam, it’s not in the list of printer supported by CUPS. I reckon its popularity is fueled by its economical nature, it’s one of the very few laser printers that fall into the ‘cheap to buy, cheap to maintain’ segment (it costs like $150 brand new, and cartridge replacement is like $3.85, which is insane!). So getting it to work with CUPS is going to require a bit more works, but thankfully there’s an open source driver out there that somebody reverse engineered to our benefits, so we’ll be using that.
Read MoreWhy isn’t anybody talking about Webmin’s awesome facelift?
So I’ve been fiddling around with remote management tools for my home server recently, after accidentally discovering Cockpit after installing Fedora (it comes preinstalled with Fedora Server 34), I started looking around for alternatives. Don’t get me wrong Cockpit is great but being a DIY I always wanted to see what kind of options are out there.
During my search I came across a vaguely familiar name: Webmin. I had limited experience with Webmin before when I was searching for a decent web panel for my VPS since it is the basis on which Virtualmin is based on. I quickly dropped it due to the horribly outdated UI (it’s a designer’s quirk, don’t ask).
Revisiting it a few years later, I just couldn’t believe my eyes when I first fire up the program, the difference is like Night and Day! Even literally more so since the current version even includes a proper dark mode that can be toggled in real time! How awesome is that?

Conducting User Interviews
As a UX designer, you’ll always focus on the user and the experience they’ll have with the product you’re designing. In this course, you’ll learn about the first phase of the design process, empathizing with users, which is critical when it comes to creating a great user experience. In order to empathize with users and understand their pain points, you’ll need to conduct interviews with real people who might use the product you’re designing.
Whether you’re conducting interviews in person or online, it’s important to be prepared before you speak with real users. You want to make the most of your limited time together and learn as much as you can about their unique perspectives. Here are a few things you can do to prepare for interviews:
