El Secreto del Cafe Perfecto

Son solo cinco los pasos que marcaran la diferencia y no robará más de seis minutos. Eso sí, hay que seguir los pasos de forma escrupulosa. Comenzamos:

1. ¿Mezcla? Olvídate: es como echar casera a un buen vino

“Para obtener un resultado óptimo hay que usar café 100 % arábica”, afirma Siffe Rabani, barista del café La Bicicleta. El arábica es un tipo de café bajo en cafeína que tiene cierta acidez y deja un postgusto dulce.

Al contrario de lo que ocurre con el café robusta, que es muy fuerte y amargo, el arábica es ideal para tomarlo solo, sin leche ni azúcar. Si aún le queda en casa medio paquete de café mezcla (fusión de arábica con robusta) y pretende poner en práctica estos pasos con él, olvídelo: “Usar mezcla es como echar casera a un buen vino”, afirma tajante Diego López.

2. Calienta el agua, pero que no llegue a hervir

El error más común al preparar café es querer hacerlo todo de una vez. Hay que cumplir los pasos. “Primero hay que llenar el depósito de agua hasta la válvula y ponerlo al fuego sin el filtro y sin la mitad de arriba de la cafetera. O sea, poniendo solo la parte del depósito del agua”, explica Diego López. Pero, cuidado, debemos apartarla del fuego antes de que el agua hierva. En este punto es normal que uno se pregunte: “¿Pero cómo sé yo que el agua ya está lista para quitarla del fuego?”. Calma, Diego López nos da la clave: “Cuando el agua empieza con un leve burbujeo es el momento de apartarla del calor”.

3. El café debe ser en grano y hay que molerlo al momento

Sí, el café hay que comprarlo en grano, porque conserva mucho mejor el sabor y el aroma. Y sí, debes comprarte un molinillo. Olvídate de moler todo el paquete de café de una vez para guardarlo en el armario hasta la próxima ocasión. O todavía peor: ni se te ocurra barajar la idea de comprar café ya molido. “El café hay que molerlo en el momento, mientras se calienta el agua, para conservar todo el aroma y el sabor”.

4. Hacer un agujero en medio cuando esté el café en el filtro

Para evitar daños físicos, lo mejor es colocar el filtro con el café y cerrar la cafetera usando un trapo que evite que nos abrasemos las manos. Porque recuerden: el agua se ha calentado antes. “Hay que llenar el filtro de café hasta el borde, pero sin prensarlo o aplastarlo, y hacer una agujero en el medio que coincida con el tubo de la cafetera italiana. De esta forma, el café sale antes y ayuda a que tenga más crema”, apunta Siffe.

Una vez que el filtro y el café están en su sitio, se enrosca la parte de arriba, se deja la tapa abierta y se vuelve a poner la cafetera en el fuego. En efecto, la tapa abierta. Si está cerrada limita el sabor del café: “Si está la tapa abierta, el agua se calienta más lentamente y está en contacto más tiempo con el café mientras va subiendo.

5. Y por último, no seas ansioso y déjalo reposar

Antes de lanzarse a servir el café, párate durante un minuto y disfruta del aroma intenso del brebaje que estás a punto de paladear. “Una vez hemos apartado la cafetera del fuego hay que dejarla reposar con la tapa bajada durante 60 segundos para que se asiente el café”, matiza Diego López.

Pasado este tiempo, ha llegado el momento de disfrutar de esa taza de buen café que has preparado tú mismo (y en menos de seis minutos). Empezar bien el día puede ser muy sencillo.

MWC 2019: Nubia Alpha unveils ‘wearable phone’


A “wearable smartphone” with a flexible display that wraps around the wearer’s wrist has become the latest flexible device to appear at the Mobile World Congress technology show.

The Nubia Alpha has a four-inch flexible OLED display built into a watch strap as well as a five-megapixel camera and can be used to make calls and send messages.

The device comes as the technology industry has welcomed its first folding smartphones – both Huawei and Samsung have revealed flexible screen devices in the last week that will go on sale this year, while Chinese firm TCL has also announced a concept for foldable screens on mobile devices.

Chinese firm Nubia – part of telecoms firm ZTE – say that while their device is naturally considered a wearable, the big screen akin to a smartphone that it houses puts it in a new category – one which combines aspects of a smartwatch with those of a phone.

The company says the device can also be used as a health and fitness tracker, like many other wearables, and contains a battery that can last up to two days.

It runs a custom version of Google’s Android operating system, and also includes mobile payment capabilities, with the first version of the Alpha due to go on sale in Europe and North America in April.

The Nubia will also support hands-free gesture control, Nubia said, meaning users will be able to navigate between different menu screens of the device.

Flexible screens of all sizes are expected to become increasingly popular in the coming years. LG announced its first rollable television at the beginning of 2019, and in the wake of Huawei and Samsung’s foldable phone announcements, reports have already surfaced claiming Apple is developing its own version of such a device.

How to fix a petulant Google Home


I had an interesting experience with one of my original Google Home units where I would ask it what the news was, it would say “here’s the latest news….” and lock up for about a minute.

The second time I would ask it it would relent and work. This became a regular thing for the past month with the only weird issue being that first request for news in the morning.

It also wasn’t just the first request, it was the first request for news. I could stream other things, change house temperature, etc…

I dropped it from the network, joined again, same thing the next day. Solution finally ended up being to forget it from my home, reset it by holding the mute button down for something like 15 seconds (it’ll warn you you’re coming up on a reset,) and then setting it up again.

Sadly turning it off and on again wasn’t the answer.

My guess is during one of the software updates something failed, resetting it cleared the evil bit/data cache, rejoining brought it back into the fold.

You can now audio Duo call another Google Home speaker, some hoops required.


It’s not quite walkie-talkie level awesome, and it requires that the person initiating the audio be recognized, know the name of the Google Home speaker the other person is at, and the person at the other end answer, but it’s a start for a decent home intercom.

It doesn’t appear the option is there by default. You’ll need to delete the speaker (or entire Home as some suggest,) and re-set it up again and then you should have Duo calling ability between any audio Google Home speaker. I tried Duo on my mini and once I unlinked and relinked the speaker, Duo appeared.

There doesn’t seem to be any way to do this without first unlinking a speaker and relinking it. Fortunately it doesn’t appear you have to unlink the entire home, just each speaker you want to enable destination Google audio on.

Alternately wait a few days and the feature will probably just show up on all your devices.

The command is “Hey Google Duo Audio call Speaker so and so”. They’ll need to answer, so it’s not exactly intercom functionality, but it’s a start.

Still no “hey google, open an intercom to Maggie’s speaker” but it’s getting there.

Momo was a hoax, and other stuff you already know


Momo’s Suicide Challenge started as a hoax in another country and spread like wildfire here when a Twitter account published a video showing someone playing a video of Momo encouraging their kids to kill themselves.

Since then it’s been seen by some guy your kid knows who can’t provide a link because it’s in YouTube kids (tap library, tap history, find link, share it)

Since then it’s been seen by some guy your kid knows who can’t provide a link because the YouTube Kids app was deleted by the parents – ah, good one kid. Your parents can’t install YouTube Kids on another device, log into your profile, swipe right into the Watch It Again territory, and see your watch history… oh wait.

Since then it’s been seen by some guy your kid know who can’t provide a link because his parents were disgusted with Google and deleted their accounts so… oh wait, you can recover and download history?

But wait, there’s a Momo on there I’ve seen it… yup, people started making Momo videos and uploading them after parents spread the hoax like wildfire. There exist momo videos in other languages in which people are warning of the hey where’s the link?

NY Mag had a great headline: How Are Kids Supposed to Learn to Be Smart Online If Adults Are Such Big Dummies?

So far the only YouTube link that shows Momo before last week (in English,) and the invention of the “suicide challenge” is this one. (not embedding, preview’s creeperific). The hoax has been in other countries before.

Police, schools, and family groups are falling for the hoax pretty much guaranteeing a crappy movie based on the suicide challenge / Momo is already in the works.

That said, there are extremely valid reasons to talk to your kids about YouTube Kids, YouTube, and anything that exposes them to predators. Just because Momo’s fake doesn’t mean they’re not going to run into something idiotic like this in the future.

Pedophiles and YouTube are a big problem these days. YouTube is a big problem these days pushing pirated content pretty much 24/7 somewhere on their YT Kids platform (why yes, I’m completely sure Trolls is free on YouTube Kids… oh wait, that is trolls… it’s just chopped up flipped reversed and out of sequence wtf)

But parents are the problem here, parents, well meaning schools, well meaning police departments who got calls from well meaning people who cried wolf, while meaning well and not demanding proof. Like the Tide Pod challenge that was a joke and people freaked and it became a real thing.

Or not, it’s real, post a link to the video and not a link to someone playing a video that looks like it’s on YouTube.

PCRADIO Internet Radio app that works with low speed Internet


Mobile users have several options when it comes to listening to Internet Radio on their devices. Some like to stream directly from the Radio station’s website, others prefer music apps with radio support to do so.

Most radio apps work well when you have a fast-enough Internet connection but most fail when you don’t. Failing does not necessarily mean that you cannot play the stream at all, but that you may experience buffering issues and other interruptions.

The default stream quality, 128 Kbit/s, uses quiet a bit of data already; a single hour of playback requires about 50 to 60 Megabytes of data. If you play music for two hours per day, you end up with up to 3600 Megabytes of data just for the streaming.

That’s exactly the situation where Radio Online – PCRADIO comes into play as it was designed specifically for low speed Internet situations (think car, subway or train ride, workplace with bad Internet connectivity..).

The service converts the radio stream to the data efficient AAC+ audio format using custom servers. Doing so reduces the required transfer rate to play the Internet Radio stream without buffering interruptions and reduces the data that playback uses significantly.

A quick test using the Android version of PCRADIO resulted in savings of about 60% when compared to the default stream of tested radio stations. The data requirement per hour of playback drops to less than 20 Megabytes per hour when you use the application.

You may also benefit from uninterrupted playback as the less demanding stream tends to work better because of the lower requirement.

PCRADIO Internet Radio

pcradio low speed internet stream

The free (with ads) or paid application has been designed to work well even in low speed environments thanks to the use of AAC+. The free version provides access to most features but it comes with advertisement in the main interface. The premium version costs €6,49 per year on Android; it removes ads and adds two additional stream quality, high quality, and low quality, to the mix.

Free users are set to medium quality, about 32 Kbit/s, automatically with no option to change the quality in the free version.

The radio app displays a list of radio stations on start. The list displays recommended stations from around the world by default. A tap on a station starts playback immediately.PCRADIO displays the artist and song name in the interface when playback starts. Options to copy the information to the clipboard and to run searches on Google or YouTube are provided as well.

You can add a station to the favorites for quick access, and tap on the information icon next to a station to display a description (if available).

A search is available to find radio stations, e.g. by name, a tap on the globe icon opens the country filter to display only stations from the selected country. The app features an equalizer that you need to activate before you may use it.

PCRADIO offers a good selection of stations but you may miss some of your favorites. The app offers no option to add custom streams to the list of radio stations, and it would not make a whole lot of sense either considering that you would not benefit from the reduced bandwidth requirements if you’d be able to do that.

You can contact the developers of the app to request support for new stations. The support email address is listed on the application’s Google Play store page.

Closing Words

If you like to listen to Internet Radio while on the go on your Android or iOS devices but run into streaming issues regularly or even only occasionally, you may want to try Radio Online – PCRADIO to find out if it resolves the issue for you.

The audio quality is acceptable; users who cannot stream Internet Radio using regular streams may prefer it regardless of the quality.

Now You: do you listen to Internet Radio regularly?

LastPass increases price of Premium plan again


LastPass increased the price of the Premium plan of its password management service in February 2019; this time to $3 per month for a Premium plan, an increase by $1 per month.

LastPass is the maker of a popular password management service. Free and paid versions of LastPass are available, and Home users may upgrade accounts to a Premium or Family plans.

The Premium version adds features such as encrypted file storage, emergency access, advanced multi-factor authentication options, and priority tech support to the feature set. LastPass enabled mobile access for free accounts in 2015, and  removed the free account limitation that restricted sync operations to device classes (e.g. PC to PC, but not PC to mobile).

lastpass price increase

Families support up to six users as opposed to the single user that a Premium license supports. It furthermore includes access to a family manager dashboard and unlimited shared folders.

LastPass Premium’s price is $3 per month if paid annually as of February 2019. LastPass increased the price from $2 per month to $3 per month in February for existing and new users; this is the second premium price increase after the increase from $1 per month to $2 per month in 2017. Both increases came after LogMeIn’s acquisition of LastPass in late 2015.

The new price took effect for new customers on February 7, 2019. Existing customers have to pay the new price when they renew the plan. LastPass sends out reminders 30-days before the expiration of a plan to notify users about the upcoming renewal.

Price comparison

An increase from $1 to $3 per month in two years is certainly something that does not look too good on paper. Compared to other premium password manager offerings, it is not too expensive, however.

Dashlane charges $5 per month for Dashlane Premium, 1Password $2.99 per month (and $4.99 for Families), Enpass asks for one-time payments for individual platforms ($11.99 per platform), and BitWarden charges $1 per month for its Family plan (there is no Premium plan).

KeePass, which I use, is available for free.

LastPass’ price matches that of the competition for the most part. Enpass’ decision to charge users a one-time fee deserves commendation in a world in which most companies move to subscription-based services.

Closing Words

The LastPass Families price remained as it was; it costs just $1 more per month and gives customers access to five additional Premium accounts.

The price increase moves LastPass’ premium offering in line with its competition.

Now You: Do you use LastPass Premium or another password manager / service? How much would you pay for such a service? (via Caschy)
