There are many brands to choose from (Thermaltake, Xion, Targus) and are available at computer stores like Best Buy or online from Newegg. You can even buy risers, or computer stands, that have ventilation. If you can't afford/find cooling mat, always prefer something hard under the laptop rather than something soft. For example, use a plastic casing, a lap desk, tray table or even a wooden cutting board to provide a solid, flat surface to allow proper airflow. Don't use your laptop on soft surfaces such as a sofa, carpeting, folded quilt or pillow. Any vents located on the bottom of your laptop will be blocked and airflow will be reduced, causing it to overheat. It may even overheat enough to catch on fire. Use a steel flat bar as an external heat sink. It works because your computer has to heat up more mass before it overheats. This also means, that the larger the bar, the longer it will take for it to overheat. It will only work if your laptop has a metal case, and it feels hot.

Make sure you have all objects you want to include in your animation imported into your scene. Place them where you want them to be at the start of your animation. Make sure you have the camera aiming at your scene. The timeline is the panel at the bottom of the Blender 3D. By default, it starts at Frame 1 and ends at Frame 250, which produces about 8 seconds of animation at 30 frames per second. If you want more frames, click End 250 in the upper-right corner of the timeline panel and enter how a different number. The playhead is the blue line in the timeline panel. This represents which frame you are currently on. Place the playhead at Frame 1 at the start. It's the icon with the circle above the timeline panel at the bottom of Blender. Select the object you want to animate, press G to grab it, and then click immediately to place it exactly where it is. This records a starting keyframe at frame 1. In animation, keyframes record changes in the motion of an object. You'll need to switch to Pose Mode to animate parts of a rig. Most video is done at about 30 frames per second. This gives you an idea of how much time has passed between frames. This records a second keyframe in the timeline. Blender will automatically calculate the position of the object for each frame in between keyframes. Continue adding as many keyframes as you need for the entire animation. You can also right-click the keyframe in the timeline and click Copy. Move the playhead to where you want the keyframe to repeat, right-click the playhead and click Paste. This is useful for repeating animations, such as a walk cycle. You can animate multiple objects in a scene at the same time in a scene. Each object has its own independent timeline with unique keyframes.

Click the record icon to turn on auto keyframing. Grab and place an object you want to animate. Move the playhead to where you want the object motion to stop or change. Move the object to where you want the object to be at the second keyframe.

If you're familiar with common phishing attempts, you'll be less likely to fall for them. University and government cybercrime or information security websites are good sources of information. For example, the Berkeley Department of Information Security and Policy has an archive of phishing messages available at https://security.berkeley.edu/resources/phishing/phishing-examples-archive. You can also find news and information at https://www.antiphishing.org/, the official website of the Anti-Phishing Working Group. A legitimate email typically will have a specific subject line that gives you a basic understanding of what the email will say. Phishing emails, on the other hand, use vague phrases such as "Urgent Reminder" or "Your Account at Risk" to alarm you. Phishing email subject lines may also start with the abbreviation "Re:" to make you think the email is a response to an email you've sent. However, if you look at the email thread you can clearly see that there are no other emails. The subject line also may use special characters, emojis, or extra spaces. These don't serve any real purpose other than to draw your attention to the email by making the subject line look different from others in your inbox. Particularly if an email comes from a business, government agency, or other organization, the sender typically proofreads carefully before sending it. Obvious spelling and grammatical errors are a red flag that the email may not be legitimate. Also pay attention to the way language is used. Phishing emails frequently use words incorrectly or include awkward turns of phrase that no one would actually say. Scammers typically try to make the email address a phishing email is sent from look official or legitimate if you just glance at it. However, upon closer inspection, you'll note that something is amiss. Instead of ending in ".com," as it should, the email address may end differently. They may include "com" in the domain to fool you. For example, you might get a phishing email from "airbnbcom.work" instead of "airbnb.com." It can take a second look to notice that odd extension. The company name may be spelled incorrectly, such as by having transposed letters or a single letter where there should be doubled letters. For example, you might get an email from "welsfargo.com" (attempting to impersonate the bank Well's Fargo). Phishing emails are desperate and insistent that the matter is urgent and you have a limited time to help or to correct a problem. Scammers want to raise a panic in you so that you give them your personal information without thinking. By the time you figure out that you've been scammed, it will be too late. Variations of this include "last reminder" emails. If you get an email claiming to be your "last reminder" of something and you never received any previous reminders, it's likely a phishing attempt. If the scammer is impersonating a friend or family member rather than a business or government agency, contact that person directly and ask if them about the email. Scammers often use copyright and trademark symbols to make their emails appear more official. However, business communications, such as emails, aren't entitled to copyright protection. A phishing email may include legitimate logos or other branding from the company or organization the scammer is trying to impersonate. They want to make their email look as believable as possible so you'll fall for the scam. Don't expect a scammer to respect intellectual property rights.
