Three flags

 

For this project, I created a digital illustration of the Swedish flag using Inkscape. I began by setting up a rectangular canvas with the traditional proportions of the flag. Next, I applied a deep blue background and added the characteristic yellow Nordic cross, ensuring that the vertical section of the cross is positioned slightly off-center toward the hoist side, as in the official design.

I used Inkscape’s vector tools to achieve clean lines and precise alignment, adjusting the shapes and colors to match the authentic appearance of the Swedish flag.

In this project, I created the flag of the European Union using Inkscape. I started by setting the document to the official 2:3 proportion and added a blue rectangle as the background. Then I designed a yellow five-pointed star and adjusted its size. Using this star as a base, I duplicated and arranged twelve stars in a circle with the help of guides and 30° rotations. Finally, I removed the guides, grouped all the elements, and saved the final design as both SVG and PNG.

To create the flag of England in Inkscape, I started by setting up a new document with a white background, which represents the base of the flag. Then I drew a rectangle that covered the entire canvas to ensure a uniform background.

Next, I created the red cross in the center, which is the main symbol of the flag of England (the Cross of Saint George). To do this, I used two rectangles: one vertical and one horizontal, both with the same red color and thickness. I adjusted their size and position so that they crossed exactly in the center of the canvas, keeping balanced proportions. Finally I set up the correct colors and I checked that all was correct.

Digital image problem 2

 Second problem:

Which resolution would the same picture need to have a 300 dpi picture?

Step 1: Convert millimeters to inches

We know that:

$$1 \text{ inch} = 25.4 \text{ mm}$$

Convert each dimension:

• Width:

  $$210 \div 25.4 = 8.267716535 \text{ inches}$$
  

• Height:

  $$297 \div 25.4 = 11.69291339 \text{ inches}$$
  

Step 2: Multiply each dimension in inches by the desired resolution (300 dpi)

• Width in pixels:

  $$8.267716535 \times 300 = 2480.31496 \text{ px}$$
  

• Height in pixels:

  $$\mathrm{-\; 11.69291339}\times 300=3507.874017\text{ pixels}$$

• Final required resolution: 
• 2480 × 3508 pixels

Digital image problem 1

First problem: 

Think you want to print out a photograph with a size of DIN A4: 210 × 297 mm

maintaining a printing quality of 200 dpi. Which resolution would the image need?

To find the required image resolution:

Step 1: Convert A4 dimensions from millimeters to inches.
1 inch = 25.4 mm

• Width: $210 \div 25.4 \approx 8.27$ in

• Height: $297 \div 25.4 \approx 11.69$ in

Step 2: Multiply by desired print DPI (200 dpi).

• Width: $8.27 \times 200 \approx 1654$ pixels

• Height: $11.69 \times 200 \approx 2338$ pixels

  Required resolution at 200 dpi: 

• 1654 × 2339 pixels

Cyber security problem 2

-  I think my telephone has a type of malicious software that makes me believe that my cell has a virus. Sometimes, it will fool me into believing that my security measures are old. In turn, they offer new updates for my security settings. So I do not know what to do… 

- Information about the problem

1 . Run a reliable security scan & remove suspicious apps:

Install a well-known mobile security or antivirus app (from the official store) and run a full scan. Then uninstall any apps you don’t recognise.

- Run a reliable security scan & remove suspicious apps

2. Clear browser data, caches, and restart in safe mode:

Malware sometimes works via browser pop-ups or hidden apps. Clearing browser history & cache helps. On Android you can reboot into Safe Mode (which disables third-party apps) to check behaviour.

- Clear browser data, caches, and restart in safe mode 

3. Check for fake alerts/scareware and avoid clicking on them: 

What you’re describing (pop-ups telling your security is out-of-date, prompting you to install something) often is a malicious trick (scareware). Be very cautious of alerts that push you to take immediate action via unknown apps or links.

 - Check for fake alerts/scareware and avoid clicking on them

4. Keep your operating system & apps up-to-date:

Updates often patch security vulnerabilities that malware can exploit. Ensuring your phone’s OS and apps are updated reduces risk.

- Keep your operating system & apps up-to-date

5. Back up your data and, if necessary, reset your phone: 

If you can’t seem to remove the malicious behaviour, back up your important files (contacts, photos) then perform a factory reset (erasing all data and starting fresh). Make sure any backup is clean (i.e., before the issues started).

 - Back up your data and, if necessary, reset your phone

Cyber security problem 1

 - My brother always uses public conections, like public libraries or cultural centers, to do his online works. He has an important job and manage sensible information about clients and business. I think this is not a good idea to use public wi-fi connections to do so… What do you think and why…

- Information about the problem

• Five good tips to avoid or solve the problem:

1. Use a Reliable VPN (Virtual Private Network):

- Information about VPN

      

·         A VPN encrypts all your traffic, even on public networks.

·         It makes your online activity invisible to others on the same network.

·         Good VPNs: NordVPN, ExpressVPN, ProtonVPN (free limited version available).

2. Avoid Accesing Sensitive Services:

- Avoid Accessing Sensitive Services

·         Never log in to banking, work dashboards, or confidential platforms on public Wi-Fi unless protected by a VPN.

·         Wait until on a secure network — or use mobile data for safer access if necessary.

3. Use Two-Factor Authentication (2FA) Everywhere:

- Information about 2FA

·         Even if someone gets your login credentials, they can’t access accounts without your second authentication method.

·         Enable 2FA on email, work apps, cloud storage, etc.

4. Turn Off Auto-Connect and File Sharing:

- Information about Turn Off Auto-Connect and File Sharing

·         Disable auto-join for open networks and file/printer sharing in your device settings.

·         On Windows/Mac, set public Wi-Fi networks as “Public” (not “Home” or “Trusted”).

5. Create a Personal Hotspot (When Possible):

- Information Create a Personal Hotspot

·         If he has a phone with mobile data, he can create a secure hotspot and work from that.

·         Far safer than public Wi-Fi, especially if he has unlimited or large data plans.

Final article

And I think that this is the best PC quality-price: 

- Graphics Card (GPU): In 2025, the most recommended graphics cards are the RTX 4070 Ti, RTX 4080 Super, and RX 7900 XTX for 1440p and 4K gaming. But if you're on a budget, the RTX 4060 and RX 7600 offer good performance at 1080p.

- Processor (CPU): The Intel Core i5-13600K or Ryzen 7 7800X3D are powerful and balanced options. If you're looking for the best of the best, the Intel Core i9-14900K or Ryzen 9 7950X3D is a premium choice.

- RAM: 16GB DDR5 is the recommended minimum, but if you need to fully optimize it, go for 32GB DDR5 6000MHz.

SSD Storage: An NVMe SSD of at least 1TB is mandatory in 2025 for fast loading. Models like the Samsung 990 Pro or WD Black SN850X are among the best.

- Power Supply: Don't skimp on the PSU. A 750W or higher PSU with 80 Plus Gold certification will ensure stability and efficiency.

- Cooling: Powerful gaming PCs generate heat, so AIO liquid cooling or high-quality fans are recommended.
