setting font in plots
Dear Reader I am trying to change the font in a plot and after several trials finally came up with the following code. plot(var_a, var_b, pch = 16, font.lab = 10, font = 10) points(var_a, var_c, pch = 3, font = 10) legend(0.1, 0.8, legend = c(?var_b?, ?var_c?), pch = c(16,3)) It does change the font in the plot (Courier), but not in the legend that does not accept the "font = ..."

[RFC PATCH 1/2] [clang]: Add AuxAttr support
This patch adds EmitTypeAuxAttribute() function to CGDebugInfo, which allows other parts of clang issue auxiliary information through an enumeration type in Dwarf information. For example, by calling DI->EmitTypeAuxAttribute(type, "ID", 1234); We can get following information in dwarf: <1><3f>: Abbrev Number: 3 (DW_TAG_structure_type) <40> DW_AT_name

descriptive statistics
Hi. In a data set I have a variable that takes values from 1 to 14. For each subgroup of values of this variable, I would like to obtain some descriptive statistics of other variables present in the data set. I've been trying with a "for" loop but I couldn't get nothing. Could you please suggest me some lines? -- View this message in context:

[LLVMdev] C++ exception handling
(Moving this discussion on list as this could be of general interest.) My current work-in-progress implementation is attempting to map out the blocks used by a landing pad before it starts outlining. It creates a table of catch and cleanup handlers with the block at which each one starts. During outlining I intend to have another mechanism to check to see if we’ve already outlined the handler

[bpf-next V1-RFC PATCH 11/14] virtio_net: setup xdp_rxq_info
The virtio_net driver doesn't dynamically change the RX-ring queue layout and backing pages, but instead reject XDP setup if all the conditions for XDP is not meet. Thus, the xdp_rxq_info also remains fairly static. This allow us to simply add the init+reg/unreg to net_device open/close functions. Driver hook points for xdp_rxq_info: * init+reg: virtnet_open * unreg : virtnet_close Cc:

virtio BPF offers incorrect packet length
Hi, I suspect that the virtio network driver calls some skb BPF programs with skb->data_end - skb->data != skb->len, but only for forwarded packets. For instance, the attached sched_cls tc program prints skb->data, skb->data_end and skb->len for each packet: <idle>-0 [000] ..s. 491.561727: 0: data: 3110080576 data_end: 3110080704 len: 262
