Razer Opus headset froze, cannot hear anything, but the blue light is turning on, it didn’t react to any buttons, I could not turn it off, the noise cancelling was still on.
I had to wait for a day until the battery ran out, then recharged it. Since then, every time I put it in pairing mode, I hear the bleeps two times, and then it shuts off.
Solution
plug the included 3.5mm cable into the Opus, then Press and Hold Volume Up + Volume Down + Power Button at the same time.

Memory object caching systems like Memcached can optimize backend database performance by temporarily storing information in memory, retaining frequently or recently requested records. In this way, they reduce the number of direct requests to your databases.
In this guide, you will learn how to install and configure a Memcached server. You’ll also learn how to add authentication to secure Memcached using Simple Authentication and Security Layer (SASL). Finally, you’ll learn how to bind Memcached to a local or private network interface to ensure that it is only accessible on trusted networks, by authenticated users.
1. Install in Ubuntu
sudo apt-get -y install php8.0-memcached memcached //depend on PHP version
2. Configure the Memcached Memory
vi /etc/memcached.conf
# Start with a cap of 64 megs of memory. It's reasonable, and the daemon default
# Note that the daemon will grow to this size, but does not start out holding this much
# memory

I was angry with my friend; I told my wrath, my wrath did end. I was angry with my foe: I told it not, my wrath did grow.
And I waterd it in fears, Night & morning with my tears: And I sunned it with smiles, And with soft deceitful wiles.
And it grew both day and night. Till it bore an apple bright. And my foe beheld it shine, And he knew that it was mine.
And into my garden stole, When the night had veild the pole; In the morning glad I see; My foe outstretched beneath the tree.
A Poison Tree By William Blake
“A Poison Tree” is a poem written by William Blake, published in 1794 as part of his Songs of Experience collection. It describes the narrator’s repressed feelings of anger towards an individual, emotions which eventually lead to murder. The poem explores themes of indignation, revenge, and more generally the fallen state of mankind.
Poem The poem relies on a trochaic beat. It consists of four stanzas and begins with an emphasis on the first person. The first person perspective changes with the use of the word “And” after the first stanza, while the emphasis on “I” is replaced
The original draft has a line drawn beneath the first stanza, which could denote that Blake originally intended the poem as concluding at the 4th line. There are also many differences between the manuscript and published versions of the poem, with the original line 3 and 4 reading “At a Friends Errors Anger Shew / Mirth at the Errors of a Foe.”
