Tag: argh don’t put your coffee that close to your laptop

Easily determine whether you can get a seat at a trendy coffee shop, even when it’s completely packed with people using laptops! All thanks to the “this seat is free” sign.

Background:

Do you own a crowded coffee shop? No? Well, you should remedy that, and then read on!

The issue:

In large cities, coffee shops are often entirely occupied by people doing work on their laptops.

Coffee shops have come up with various strategies for dealing with the pros and cons of being a low-cost “co-working space,” but it’s often a problem for people who just want to sit down: a laptop-using individual with an external mouse and some notes can easily occupy an entire four-seat table, while only using one chair and ~50–75% of the actual table area.

There’s enough remaining room for two additional people to have coffee at that table without impacting the laptop user!

Proposal:

The easy solution is to have a set of “this seat / this part of the table is open, please feel free to use it!” signs at the front of the cafe (Figure 1).

A patron who only anticipates using 50% of a table could take one of these signs and put it on the unused section of their table (even if there isn’t room for a second laptop).

Fig. 1: If you are using only part of a table (and don’t mind if someone uses the rest of the table), you can put a “THIS SEAT IS OPEN” sign on the other side of the table.

Conclusion:

This would be really cheap to implement and doesn’t really have any downsides.

One objection is: “couldn’t patrons also accomplish this by asking if the laptop-user minds if they sit down?” Answer: yes, but that is irrelevant from the cafe owner’s perspective, since people tend to assume a no-tables-remaining cafe is FULL. Even if they “should” have just asked around, it still results in lost business for the cafe owner.

PROS: Could increase the effective number of seats in a cafe without requiring more space or furniture.

CONS: Maybe weirdos would use these signs as a way to try to lure other coffeeshop patrons into sharing a table with them, so they could then subject them to annoying and unwanted conversation.

The horrifying secret that APPLE, GOOGLE, and MICROSOFT don’t want you to know about laptop longevity! Stop being part of the “laptop rat race” with this new insane beverage-related tip. Tip number 5 will shock you!

Background:

Millions of laptops are destroyed every year by spilled drinks (Figure 1). Unfortunately, this is a difficult problem to address, because laptops and beverages are frequently in close proximity.

Fig. 1a (top) and 1b (bottom): You have probably either experienced this situation first-hand or observed it happen to someone else. If only there had been some warning ahead of time about the peril the laptop was in!

Proposal:

If the glass-full-of-liquid danger were more immediately obvious, many laptops could be saved from a thirst-quenching death—the laptop user would simply need to place the drink slightly farther away from the laptop than they normally would.

By adding a ring of laser emitters to the beverage container, the spill danger can be made obvious: the lasers will project a circular “spill danger zone” on the table, informing you of any imperiled electronics (Figure 2).

Fig. 2: The laser emitters on the top of the glass (shown as red triangles) project a “spill danger zone” region around the glass. You should move any sensitive electronics outside of this area.

An advanced model of this idea could also have an integrated camera: this would allow it to only project the “danger zone” markings if it actually detected an object in the spill area, instead of all the time (which might get annoying).

PROS: Saves your laptop from destruction!

CONS: The lasers might melt people’s eyeballs when you raise the glass to drink from it.
